DC Power Supplies – Integrated with Internal Batteries

Integrated Power System (IPS) Series

A unique multi-function power supply which incorporates built-in battery back-up and numerous power accessories within a single 2RU (3.5″) chassis, thus eliminating time – consuming system integration, component sourcing and installation, while saving precious rack space – ideal for any low – to – medium power application requiring AC fault tolerant operation.

A precision regulated power supply / charger, back-up battery, low voltage battery disconnect, output metering, LED status and Form C alarm contacts are all pre – wired and calibrated within the unit for plug – and – play operation. Plug-in terminals are provided for easy wiring of an additional parallel rectifier input, or external batteries for increased back-up capacity.

The batteries are always in-line with the load, thus there is no interruption from relays or transfer switches in the event of AC loss. Batteries are recharged when AC is restored. A manual battery disconnect switch allows internal or external battery service or replacement while the system is running. Models available for -48, +24 and +12 VDC applications.
