The EOL and HBC series AC/DC power supply is an Industrial Grade product, specially designed for 3U and 4U x 19in Rack Power Systems, with a number of power supply modules connected in parallel.

The rack power systems are fully assembled and configured to customer specifications for voltage and power requirements. Each module is a Plug-in unit, able to be inserted or removed from the rack without interruption to the power.

The 3U x 19in Rack can take up to 6 x 200W modules and the 4U x 19in Rack can take up to 5 x 300W or 500W modules in parallel.Best suited to powering critical loads where continuous power is required, in addition, systems can be designed with battery back- up and various alarms.Furthermore, a number of racks can be connected in parallel for high power systems.
