AC Electronic Loads

Our rental AC electronic loads are installed with 55 common waveforms. Crest factor and power factor are user programmable, as are voltage and current ranges.

When compared to a traditional resistive load bank, a programmable AC load offers much greater functionally. Sink values can be adjusted in small increments into the milliamp range, under various waveforms and power factors. Whereas, a traditional resistive load bank typically operates at power factor unity and does not have the programmability necessary to create complex load steps.

Due to the unpredictability of real world user behaviour, the operating waveform of an AC device can often have many unusual qualities. Our AC loads allow the complex loading of an electrical circuit to be precisely simulated. This is advantageous during research and testing, as any performance issues can be identified and rectified before production commences.

A front panel memory with an auto sequencing function is provided with every AC load from ETPS. Stored within the units non-volatile memory is a waveform bank. When in constant current operation the user can select between sine, square and DC waveforms.

Peak currents can be simulated with the crest factor mode. A leading or lagging power factor can be set with adjustments from unity, to between 0.85 and 0.3. The desired wave can be recalled from the front panel or selected via a computer interface.
