• EMI (radiated emissions) conform to Class B when this Power Supply is installed in a control panel.
• EN/IEC 61558-2-16
  The S8VK-X was designed based on EN/IEC 61558-2-16.
  Currently, IEC 61558-2-17 has been replaced by IEC 61558-2-16.
  When certification was received for EN/IEC 60204-1 (Machinery Safety), it was necessary to go through a control transformer to the control circuits. However, a control transformer is not always necessary for product that have been certified for the safety standard for OVCIII or for product that use a transformer that conforms to EN/IEC 61558-2-16.
• Safety Standards for a DC Input
  When DC is used, UL 62368-1, cUR (CSA C22.2 No. 62368-1), EN/IEC 62368-1, EN 50178 and EN/IEC 61558-2-16 are applicable to safety standards.
  Safety standard compliance is achievable by connecting a UL-certified fuse as specified below.
  Select an external fuse that satisfies the following conditions:
  S8VK-X03005-EIP, S8VK-X06012-EIP, S8VK-X06024-EIP (350 VDC or more, 6 A)
  S8VK-X09024[]-EIP, S8VK-X12024[]-EIP, S8VK-X24024[]-EIP (350 VDC or more, 8 A)
  S8VK-X48024[]-EIP (350 VDC or more, 12 A)
• To comply with PELV output requirements for EN/IEC 60204-1, ground the negative side of the output (-V) to a protective earth (PE).

Definitions of the Terms Under Ratings, Characteristics, and Functions

Input conditions	Efficiency	The value is when both rated output voltage and rated output current are satisfied.
	Voltage range	Do not use an inverter output for the product. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal temperature of the product may result in smoking or burning. If the input is connected to a UPS, do not connect a UPS with a square-wave output. Doing so will cause the internal temperature of the product to increase, possibly causing smoking or burning.
	Frequency
	Input current	The value is when both rated output voltage and rated output current are satisfied.
	Leakage current	The value is determined according to the Electrical Appliances and Material Safety Act.
	Inrush current	Values for a cold start at 25°C. Refer to Inrush Current, Startup Time, and Output Hold Time on catalog for details.
Output characteristics	Voltage adjustment range	If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than of the voltage adjustment range. When adjusting the output voltage, confirm the actual output voltage from the product and be sure that the load is not damaged.
	Ripple noise voltage	The value is when both rated output voltage and rated output current are satisfied. A characteristic when the ambient operating temperature is 25°C.
	Static input variation influence	This is the maximum variation in the output voltage when the input voltage is gradually changed within the allowable input voltage range at the rated output voltage and rated output current.
	Load variation influence	100 to 240 VAC input, in the range of 0 A to the rated output current.
	Startup time	The value is when both rated output voltage and rated output current are satisfied and at room temperature (25°C). Refer to Inrush Current, Startup Time, and Output Hold Time on catalog for details.
	Hold time	The value is when both rated output voltage and rated output current are satisfied and at room temperature (25°C). Refer to Inrush Current, Startup Time, and Output Hold Time on catalog for details.
Environment	Ambient operating temperature	At -40 to -25°C, time will be required before the rated output voltage is output after the input voltage is input. Also, the ripple noise value may exceed the value shown in the above table.
Reliability	MTBF	MTBF is calculated according to JEITA RCR-9102. MTBF stands for Mean Time Between Failures, which is calculated according to the probability of accidental device failures, and indicates reliability of devices. Therefore, it does not necessarily represent a life of the product.

* Communication cycle can be set from 100 to 10,000 ms. The indication update cycle is 50 ms.

Inrush Current, Startup Time, and Output Hold Time

Note: Twice the normal inrush current will flow during parallel operation or for backup operation. Also, if crossover wiring is used for N number of Power Supplies, an inrush current of N times the inrush current for a standalone Power Supply will flow. Therefore, check the fusing characteristics of fuses and operating characteristics of breakers making sure that the external fuses will not burn out and the circuit breakers will not be activated by the inrush current.

Overload Protection

When the load current reaches 121% to 160% of the rated current for S8VK-X03005-EIP, S8VK-X06012-EIP, S8VK-X06024-EIP, and S8VK-X12024[]-EIP, 101% to 110% for S8VK-X09024[]-EIP, or 151% to 165% for S8VK-X24024[]-EIP and S8VK-X48024[]-EIP, output voltage is automatically lowered to protect the Power Supply from short-circuit currents and overcurrents.
When the output current falls within the rated range, the overload protection function is automatically cleared.

Note: 1. Internal parts may possibly deteriorate or be damaged if a short-circuited or overcurrent state continues during operation.
2. Internal parts may possibly deteriorate or be damaged if the Power Supply is used for applications with frequent inrush current or overloading at the load end. Do not use the Power Supply for such applications.

Overvoltage Protection

Overvoltage will be detected to prevent the load from being subjected to excessive voltage when the feedback circuit in the Power Supply fails, etc. If an excessive voltage that is approximately 130% of the rated output voltage (but approximately 110% of the rated output voltage for only the S8VK-X09024[]-EIP) or more is output, the output voltage is shut OFF.
Reset the input power by turning it OFF for at least three minutes and then turning it back ON again. Note: Do not turn ON the power again until the cause of the overvoltage has been removed.

Communication Reset Function

This function temporarily resets the communication settings to their factory default values. Use this function when the IP address previously set is no longer known and communication is not possible.

Setting Method

(1) With the reset key pressed, turn on the power supply.
(2) Continue to hold the reset key for 10 seconds.
While pressed, an alarm indicator will flash in 0.5-second intervals.
(For models with an indication monitor, the main display and operation indicator will also repeatedly turn all indicators on and off in 0.5-second intervals.)
(3) After 10 seconds have elapsed, the system shifts into the communication reset state, and the communication setting values temporarily reset to their factory default values.
In the communication reset state, the alarm indicator will flash in 1-second intervals. (For models with an indication monitor, the main display and operation indicator will return to normal operation.)
(4) In the communication reset state, reset the communication settings from the host device.
(5) After setting, turn on the power supply once again, and confirm that the set values have been changed.
Note: 1. After confirming that the product output indicator has turned off, turn on the power supply once again.
2. The only way to exit the communication reset state is to restart the power supply.
3. If you do not change the communication settings during step (4), settings will return to their prior values once the communication reset is ended.

Switching Indications

All indicators of the indication monitor will be lit for 1 second when power is turned on. After that, each status can be displayed using the Indication switching key.

Peak Hold Current

The output current maximum value is stored as the peak hold current. (5 ms average value)
Measurement is not performed for approximately 3 seconds immediately after the input power is turned ON.

Peak Hold Curmrent Reset

When the peak hold current is displayed, it can be reset by pressing the Reset key for 3 seconds or more.

Note: For types without an indication monitor, it is not possible to reset the peak hold current via reset key operation.

Replacement Time Calculation Function

This Power Supply is equipped with electrolytic capacitors. The electrolyte inside the electrolytic capacitors penetrates the sealing rubber and evaporates as time passes after it is manufactured. This causes deterioration of characteristics, such as decreasing the capacitance. Due to this deterioration of the characteristics of the electrolytic capacitor, this Power Supply decreases its performance as time passes. The replacement time calculation function calculates an approximate period left for maintenance of this Power Supply due to deterioration of electrolytic capacitors. Use this function to know the approximate replacement time of the Power Supply.

Note: The replacement time calculation function indicates an approximate period left for maintenance, based on deterioration of the electrolytic capacitors. It does not predict failures resulting from other causes.

Principle of Operation

The deterioration speed of the electrolytic capacitors varies considerably with the ambient temperature. (Generally the speed follows the Arrhenius Law, i.e., for every 10°C increase in the temperature, the rate of degradation doubles.) The S8VK-X monitors the temperature inside the Power Supply, and calculates the amount of deterioration according to the running hours and internal temperature.

Note: 1. Due to degradation of internal electronic parts, replace the Power Supply approximately 15 years after purchase even if the replacement time calculation for years and percentage do not appear.
2. The replacement time is accelerated or decelerated according to operating conditions. Periodically check indication.
3. The accuracy of the replacement time calculation function will be reduced in applications where the input power turns ON and OFF frequently.

FUL is indicated at the time of purchase (when initially powered on), and continues to be indicated for approximately one month.
Afterward, the state of deterioration for the electrolytic capacitor is calculated based on the usage environment, and HLF
indicated when deterioration progresses. When the years until replacement reaches 5 years or less, it is indicated in 0.1 step increments within the range of 4.9 to 0.0. (Depending on the usage environment, the number of years may be indicated after FUL without HLF being indicated.) (Communication)
Communication is calculated in 0.1 step increments within a range of 15.0 to 0.0.

Note: The number of years until replacement may vary if there are frequent load variations or in locations where the ambient temperature fluctuates drastically.

Percentage until replacement

With the number of years until replacement at the time of manufacture set as 100%, as deterioration of the electrolytic capacitor progresses through use, it decreases in 0.1% step increments.

Difference between Expected Life and Replacement Time

OMRON calculates the expected life based on the following conditions.
1. Rated input voltage
2. Load rate: 50%
3. Ambient temperature: +40°C
4. Standard mounting

Note: As the values were calculated using an aluminum electrolytic condenser temperature rise test, they are not guaranteed. Use this data as a reference for maintenance and replacement time calculation.

The expected life span of the S8VK-X is 10 years minimum. Also, a replacement time calculation function is included among the functions of the S8VK-X. The replacement time is the service life (the Power Supply’s internal temperature is monitored at all times) of the internal electrolytic capacitor in actual operating conditions, and varies according to the customers operating conditions. 15 years is taken as the maximum period of the maintenance forecast.

Total Run Time

The accumulated value of the product’s time powered on is measured as the total run time. (With indication monitor)
Total run time increases in 1 (kh) steps with use.
(Communication)
Total run time increases in 1 (h) steps with use.

Time Chart

Continuous Run Time (Communication Only)

The product’s time powered on is measured as continuous run time, and the continuous run time increases in 1 (min) steps with use. Continuous run time will be reset when power is turned off.

Time Chart

Note: 1. The continuous run time does not include the time that the Power Supply is OFF.
2. The continuous run time measures the total time that power is being supplied and is not related in any way to
deterioration in the electrolytic capacitor built into the Power Supply or to the effects of the ambient temperature.
