DESCRIPTION:

The IMARK 5020RM Regulated Power Supply operates from a 240 Volt AC power source and provides a 13.8 Volt DC output to operate 12 Volt (nominal) equipment. The 5020RM Power Supply includes over voltage protection, fold-back current protection, and short circuit protection, while large filter capacitors provide a low noise output. The 5020RM is housed in a 3RU 19" rack mounting cabinet. The front panel includes meters for Load Voltage, Load Current, Battery Voltage, Battery Current, as well as LED indicators for other status notification.

The IMARK 5020RM Power Supply features a linear design and operates at greater than 50% efficiency. It provides 20 Amps continuous output power. The design is compact and includes a rugged all metal housing with a large aluminium extrusion on the rear panel to provide excellent heat dissipation. Connectors are provided on the rear panel for easy connection to the AC Input, and Load, Battery, and low current output, as well as a DB25 connector for remote monitoring purposes.

The IMARK 5020RM includes a Battery Back-Up feature that automatically changes from power supply to battery depending on the state of the AC Input. It also includes a low voltage battery release to protect the battery and equipment in the event of a prolonged mains power failure.

The IMARK 5020RM is supplied with a comprehensive operator's manual, a 1.8 metre AC Cable that plugs into the IEC socket on the rear panel during installation, Cable and Connectors for Load and Battery, and spare fuses.
