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 buffer current or extend hold-up time, any given number of buffer
units can be installed in parallel.
Activation threshold typ. 45V Ju mper in position “45V fixed”
Buffering starts if terminal voltage falls below 22.5V.
typ. Vin –2V Jumper in position “Vin –2V”
Buffering starts if the terminal voltage decreases by
more than 2V. Buffering 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
buffering starts immediately.
