The IMARK 5020BM 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 5020BM Power Supply includes over voltage protection, fold-back current protection, and short circuit protection, while large filter capacitors provide a low noise output. The 5020BM is housed in a 3RU size Bench-top cabinet. The front panel includes Meters for Output Voltage and Output Current, and LED indicators for critical status notification.

The IMARK 5020BM 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, Load, and Remote Voltage Sense output, as well as a DB25 connector for remote monitoring purposes.
