Intepro's New DC Electronic Load with Energy Recovery to AC Mains

New ELR9000 Series is designed for power supply, battery and other dc load testing; offers full suite of load test options; includes synchronized ac output that can return over 90% of load energy to the utility grid

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 95% 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.
