DC Electronic Load with Energy Recovery to AC Mains

Intepro Systems, a market leader in power component and power system automated test equipment (ATE), introduces the ELR9000 Series of electronic DC loads.  A unique feature of the ELR9000 Series is an integral, grid-synchronized inverter designed to return up to 94% of the load test energy back to the grid. The rack-mounted unit is available, off-the shelf, with output ratings of 3.5 kW, 7 kW and 10.5 kW — scalable to 105 kW.

The ELR9000 Series offers four common regulation modes: constant voltage, constant current, constant resistance and constant power. The FPGA-based operational controls include a function generator and a table-based regulation circuit for the simulation of non-linear internal resistances. Intepro’s PowerStar 6 software package enables the creation of test routines using a drag-and-drop menu where coding can be performed without programming.

“Our new ELR9000 Series of electronic DC loads offers all the necessary features of today’s electronic loads — plus the added benefit of energy recovery to mains,” said Gerard Sheehan, Intepro’s Chief Technical Officer. “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.”

Intepro Systems offers electronic loads as stand-alone units or as complete test systems. Maintenance contracts and onsite calibrations are also available for its test systems. For more information about this product, download the ELR9000 Series data sheet.
