Jumper in position “Vin –2V”
Ripple and noise voltage max.
max. 400mVpp 10A, 20 Hz to 20 MHz, 50Ohm
max. 600mVpp 20A, 20Hz to 20MHz, 50Ohm
may increase below -10°C
250mVpp 5A, 20Hz to 20MHz, 50Ohm
Hold-up time min. 0.1s 45V, 20A
typ. 0.15s 45V, 20A
min. 13.4s 45V, 0.1A
typ. 21s 45V, 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. 45V Jumper in position “45V xed”
Buering starts if terminal voltage falls below 22.5V.
typ. Vin –2V Jumper in position “Vin –2V”
Buering starts if the terminal voltage decreases by
more than 2V. Buering ends when terminal voltage
increases by more than 2V.
Voltage changes slower than 1.1V/s will be ignored
unless the voltage is above 45V. Below 45V
buering starts immediately.
