Low Voltage Disconnect and Monitor – Rack Mount

Low Voltage Disconnect and Digital Battery Monitor / Alarm Integrates Rack Mount Rectifiers into a Fully Functional DC Power System.

This 1RU assembly contains numerous DC control and monitoring features that integrate power and distribution components into a highly functional system. Built in features include: low voltage disconnect, digital monitor of voltage and amperage, battery disconnect breaker, and alarm contacts. The digital display monitors bus voltage, battery voltage, system output current, and low voltage connect / disconnect set points. Alarm contacts actuate on low voltage and battery disconnect conditions. Rear panel bus bars provide ample terminal landings for easy integration with rack mount rectifiers, distribution panels and batteries.

Features:

Digital monitor displays system bus voltage, battery voltage, total rectifier amperage, and connect / disconnect voltage set points, and system ambient temperature
For use with 12V, 24V, and -48V systems
Solid state (FET) low battery voltage disconnect with adjustable set points and manual over ride switch for system maintenance / testing, with adjustable low battery alarm contact alerting to impending system shutdown
100 Amp battery disconnect breaker for system protection and easy testing and maintenance
Form C alarm contacts
All these functions in a compact 1 RU unit, minimizing system rack space
