S8FS-C

Conditions

Inrush Current, Startup Time, and Output Hold Time

Note: Twice the normal input current will flow for a redundant system.

Sufficiently check the fusing characteristics of fuses and the

operating characteristics of breakers and select fuses and

breakers so that external fuses will not burn out or breakers will

not operate due to inrush current.

Ripple Noise Voltage

The specified standard for the ripple voltage noise was measured with

the following measurement circuit.

Efficiency

The value is given for the rated output voltage and rated output current.

Input

Voltage range

Although some inverters give 50/60 Hz as the output frequency, do not use an inverter output as the power

source for the Power Supply. Doing so may result in smoking or burning due to internal temperature

increases in the Power Supply. If you connect a UPS to the input, do not connect one with a square wave

output.

Frequency

Current

The value is given for the rated output voltage and rated output current.

Inrush current (for a cold start at 25

°C) The value is given for a cold start at 25°C. Refer to following for details.

Output

Voltage adjustment range

If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by 10% or more over the

voltage adjustment range.

When adjusting the output voltage, confirm the actual output voltage from the Power Supply and be sure

that load is not damaged.

Ripple & Noise voltage

The value is given for the rated output voltage and rated output current.

The value is for an ambient operating temperature of 25

°C.

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

This is the value when the output current is changed from 0 A to the rated output current while the input

voltage is within the allowable input voltage.

Startup time

The value is given for the rated output voltage and rated output current.

The value is given for a cold start at 25

°C. Refer to following for details.

Hold time

The value is given for the rated output voltage and rated output current.

Refer to following for details.
