The bridging time of the Powerpac depends on the connected load



Example - Table for common unit combinations

Device configuration	Load current at 24 V	Bridging time
RZ8 + 1x Holding magnet	0,115 A	approx. 9 minutes 48 seconds
RZ8 + AM-S	0,350 A	approx. 3 minutes 28 seconds
RZ8 + 2x AM-S	0,600 A	approx. 2 minutes 5 seconds
RZ8 + AM-U	0,400 A	approx. 3 minutes 3 seconds
RZ8 + 2 x AM-U	0,750 A	approx. 1 minutes 42 seconds

The Powerpack keeps the output voltage of the power supply constant at 22 VDC over the bridging period. When the stored energy is used up, the PP3 switches off the output voltage to 0 VDC.

CAUTION: A short circuit of the charged Powerpac can damage the electronics. Please check the Powerpac after a short circuit and replace it if necessary. The defective Powerpac can be repaired in many cases. Please send it to Protronic, stating a QS number.

Note:
When using the PP3 in a hold-open system type RZ8 with the aBZ Z-6.500-2436 aBG RZ8 RZ24-FA, it is no longer necessary to change the loop resistance from 4k7 to 5k9.

Notice:
The Powerpac type 3 (PP3) replaces the Powerpac type 2 (PP2). The PP3 is downward compatible and can therefore be used as a replacement for a PP2.
