Rated output current nom. 20A

Current limitation min. 20A Electronically limited

Output voltage typ. 22.5V Jumper in position “22.5V xed”

typ.

1V below input

voltage

Jumper in position “Vin –1V”

Ripple and noise voltage max. 200mVpp 20Hz to 20MHz, 50Ohm

Hold-up time min. 0.2s 22.5V, 20A

typ. 0.31s 22.5V, 20A

min. 28s 22.5V, 0.1A

typ. 43s 22.5V, 0.1A

To increase buer current or extend hold-up time, any given number of buer

units can be installed in parallel.

Activation threshold typ. 22.5V

mper in position “22.5V xed”

Buering starts if terminal voltage falls below 22.5V.

typ. Vin –1V Jumper in position “Vin –1V”

Buering starts if the terminal voltage decreases by

more than 1V. Buering ends when terminal voltage

increases by more than 1V

Voltage changes slower than 0.54V/s will be ignored

unless the voltage is above 22.5V. Below 22.5V

buering starts immediately.
