The Valere power system is a flexible system that may be equipped with a variety of plug-ins, such as rectifiers and
ring generators. The field cabinet uses one Valere shelf configured for a –48 V DC primary output. This shelf is
equipped with a Distribution Module, which includes ten fused circuits and four circuit breakers.
The alarms and displays are described in
for a complete description of the Valere Power System Product.
Valere Plug-Ins - System Controller
The System Controller monitors power plant functions and provides visual and electronic alarm information. For
lead-acid batteries, the controller can regulate the rectifier bus voltage in response to battery temperature, to
prevent battery thermal runaway.
Distribution Module
The Valere Distribution Module provides 10 plug-in (GMT) alarm-indicating fuses for the fused distribution of –48 V
DC power and connectors for battery temperature probes.
The Distribution Module includes four battery breakers that are used to manually disconnect the batteries from the
bus for installation and service of the batteries.
Placing the battery switch in the OFF position does not isolate the batteries. A short from a
WARNING
battery terminal or bus bar to a grounded cabinet part will create a high-current short circuit. Use
caution when working on batteries and follow standard procedures.
Rectifiers
The rectifiers generate –48 V DC from 120/208/240 V AC input. The –48 V DC outputs of all rectifiers are tied
together on a backplane bus. A minimum number of rectifiers are required to power the equipment and charge the
batteries.
