Plug-in programmable modules for energy-recovering DC load system

30 March 2016

Intepro Systems announced the ELR 5000 modular, programmable DC load, housed in a 6U, 19” rack enclosure.

The ELR 5000 is able accommodate up to 10 completely self-contained, fully-programmable DC load modules with 320W nominal power, each. 

The modules can be used separately or in parallel, providing up to 3200 Watts. Up to 93% of the load power is returned to the source, offering exceptional energy savings in production test of DC power sources.    

The ELR 5000 Series offers three common regulation modes: constant voltage, constant current and constant power. Modules are offered in two input voltage/current ranges: 0-80V/0-25A and 
0-200V/0-10A. Each module is equipped with touch-panel controls and a built-in sequence generator. A USB port provides flash-drive access to upload and save test sequences. An Ethernet/LAN port enables remote control of all functions via SCPI language or Modbus protocol. 

Gerard Sheehan, Intepro's Chief Technical Officer, said the ELR5000 provides a combination of fully-programmable, modular loads in a compact rack-mount system with the added benefit of energy recovery. Recovering the load energy reduces energy costs. It also offers a cost-effective alternative to the expensive cooling systems used by conventional air- and water-cooled loads to dissipate energy as heat.
