11.1 General - Product description PBDU 4U/23”
Figure 11-1 PBDU 4U/23”
The Power-One PBDU 4U/23” includes a complete system controller plus battery and load distribution in a
4U unit. The Compact Distribution is compatible with various types of Power-One subracks/rectifier
shelves, and may be configured for a variety of battery and load breaker selections.
The distribution unit is designed for switching the battery and load on and off. All DC distribution breakers
are supervised by measuring voltage drop across each breaker. MCB's (breakers), which are not
connected to any load, will not cause breaker alarm even if they are left open.
Due to small leakage current (2,5 - 3 mA) through the alarm circuit the voltage measured with a DVM
(Digital Volt Meter) on an open breaker output, will be nearly equal to output rectifier voltage. If a battery
breaker fault occurs or is simulated it might take from 2 - 10 minutes before the fault is indicated, depending
on the battery condition.
