High-power regenerative DC load operates from 360-528 Vac grid

Intepro Systems introduced the ELR 9000 HP Series of regenerative, programmable electronic DC loads. This latest version of the popular ELR Series is designed to accommodate three-phase mains between 360 V – 528 V AC. The increased power density of HP Series units provides load ratings of up to 15 kW in a single 3 U rack-mounted instrument. A master-slave bus can be used to connect as many as 16 units in parallel to test loads of up to 240 kW. A unique feature of the ELR 9000 HP Series is an integral, grid-synchronized inverter designed to return up to 94.5% of the load test energy back to the grid.

The ELR 9000 HP 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.

“The wide input voltage of the new ELR 9000 HP Series of electronic DC loads is especially important to our customers who have manufacturing facilities in multiple global locations,” said Gerard Sheehan, Intepro’s Chief Technical Officer. “In addition, the regenerative output is even more valuable in these higher power density units, eliminating the need for 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.
