Enclosure Power System

Power Transmitters and Maintain Back Up Batteries in Outdoor Enclosures.

12/24 VDC Power, 150 watts

Designed specifically for back plane or din rail mount in NEMA enclosures

Simultaneously powers load and maintains back up battery

Rated for extreme temperature operation -20° to 60° C (-40° F to 140° F)

Temperature compensated output, prolongs battery life

Alarm contacts and low voltage disconnect built in

EPS

Power Supply, Battery Charger, Alarms, and Low Voltage Disconnect all in One Unit.

As the need for broadband transmitters, cameras, and monitoring in local and remote outdoor applications increases, so does the need for a power system designed for the particular application. Common power supplies are deficient in outdoor enclosure and SCADA applications: they suffer short life due to the temperature extremes, their fixed output voltage overcharges back-up batteries in high temperatures and under chargers in low ambient, and absent are essential remote alarms and low voltage disconnect.

The Enclosure Power System is designed specifically for outdoor cabinet applications which typically include back up batteries. The environmentally hardened power circuitry provides 12 or 24 volts to the load and maintains the back-up batteries. A sense circuit adjusts charge voltage based on temperature ensuring batteries are properly maintained no matter the climate.

An important additional feature is a low voltage disconnect circuit that removes the load from the batteries after an extended power outage, thus preventing total discharge and allowing rapid replenishment when AC is restored. There are also alarm contacts that can be user configured to monitor several vital functions of the system and relay information to base station that service is needed.

The low profile rugged anodized aluminum case is designed for enclosure mount, either on back plane or din rail. The front panel terminal for AC input, battery and load make wiring easy. Status lights give quick visual indication of what’s going on with the system.
