AC and DC Electronic Loads

NH Research DC Electronic Loads are available in Modular, High-Current and High-Voltage models. Each has their own specific set of features suited for specific applications.  The 120 volt 4760 series high current loads and 600 volt 4700 series high voltage loads are available with  power levels from 1 to 36 kW. The new 4350 series modular loads, which offer 150, 300 and 600 Watt plug-in modules, are mounted in a controller mainframe up to 2400 Watt per chassis.

NH Research AC Electronic Loads were designed for test applications that require linear and non-linear AC loading in several emulation modes with Power and Crest Factor control. This programmable versatility allows testing with a wide variety of potential field operating conditions to assure unit-under-test (UUT) reliability.


Internal measurements eliminate need auxiliary test equipment

All NH Research AC and DC Electronic loads have built in built in fast waveform digitizers that enable precise measurements and transient recording. This eliminates the needs for auxiliary measurement equipment such as DSO’s and DMM’s and associated cables.
