Average value

× 100%

Operating time

Operating time repeat error:

±50 ms

Overvoltage:

Measured when input suddenly changes from 70% to 120% of setting.

Undervoltage:

Measured when input suddenly changes from 120% to 70% of setting.

The input voltage, however, must be between 70% and 125% of rating.

Startup lock time

Startup lock time repeat error:

±0.5 s

(The operating time when the operating time is set to the minimum value and the power supply suddenly

changes from 0% to 100%.)
