High Power Regenerative DC Load Operates from 360-528 Vac
Intepro Systems introduces 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 360V - 528V AC. The increased power density of HP Series units provides load ratings of up to 15kW in a single 3U 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 240kW. 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. Inteproâ€™s PowerStar 6 software package enables the creation of test routines using a drag-and-drop menu where coding can be performed without programming.
â€œThe 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,â€ said Gerard Sheehan, Intepro's Chief Technical Officer. â€œIn 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.â€
