The ELPA-32611 series simulate real loads used in medium to high power AC applications. The standard range is comprised of 6 units that sink up to 300V at 12.6kVA.
Each Load has a high peak current capability of up to 50% above its continuous rating. The crest factor can be adjusted between 1.5 and 3.5.
- Adjustable Power Factor and Crest Factor Modes
- GPIB and RS-232 with LabVIEW Drivers
- Front Panel Memory Function
- DC to 400Hz Operation
- Bank of 55 Waveforms
- Isolated Scope Output
Operating Ranges and Features
The power factor can also be adjusted in order to recreate capacitive and inductive loads. An isolated analogue current monitor output is provided to allow the waveform to be viewed on an external scope.
Another benefit of these AC Loads is that they can also be used to sink DC Sources. This can often save laboratory space and the expense of purchasing a dedicated DC Load.
The units are built with switchable automatic sense adjustment to counter the voltage drop in the load lines. Two sink levels can be preset and switched between. To aid production testing higher and upper limits can be set. Units are then automatically flagged GO or NG.
Interfaces and Control
Along with front panel control and display both IEEE 488.2 and RS-232 interfaces are provided as standard.
Safety and Protection
A host of protection features guard the unit against over power, voltage, current and temperature.
These Loads are used in a variety of applications including power transformer, DC/AC Inverter, general R&D and laboratory work along with UPS output testing and ATE systems.

Frequently asked questions
When using the watt and VA meter, are the W and VA values visible at the same time with voltage and current?
The front panel of the unit has 2 × 4½ digit displays. This ordinarily shows voltage and current simultaneously. With one button press the displays can be switched to display W and VA simultaneously. Should you use the computer interfaces then commands for measuring V, A, VA and W are also available.
