The ELR 9000 HP Series of regenerative, programmable electronic DC loads is the latest version of the popular ELR Series.

Designed to accommodate three-phase mains between 360V and 528V AC, the increased power density of HP Series units provides load ratings of up to 15 kW 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 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.  

Intepro Systems offers electronic loads as stand-alone units or as complete test systems. Maintenance contracts and on-site calibrations are also available for its test systems.
