Rated output current nom. 20A
Current limitation min. 20A Electronically limited
Output voltage typ. 22.5V Jumper in position “22.5V fixed”

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 buffer current or extend hold-up time, any given number of buffer
units can be installed in parallel.
Activation threshold typ. 22.5V Ju mper in position “22.5V fixed”
Buffering starts if terminal voltage falls below 22.5V.
typ. Vin –1V Jumper in position “Vin –1V”
Buffering starts if the terminal voltage decreases by
more than 1V. Buffering 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
buffering starts immediately.
Status lamp flashes 10Hz
