The EAC-3S is based on a linear platform ensuring a very clean output waveform. This three phase AC Source can be used in DC, single or three phase mode.
With sine, square, triangular and arbitrary functions the test engineer can simulate a wide range of real world conditions. Voltage and current limits can be set individually for each phase. Further imbalances can be programmed by altering the phase relationships.
- Fixed, 50Hz, 60Hz, 400Hz and Variable Frequency
- LAN, GPIB, RS-232, RS-485 and USB Options
- Separate V and I Setting for Each Phase
- Single, DC or Three Phase Operation
- Adjustable Phase Relationships
Operating Ranges and Features
Each phase can be set from 0-360° when compared with the internal sinewave reference. A quick setting function enables the output frequency to be set to 50, 60 or 400Hz. In adjustable mode a range of 1-500Hz is standard. This can be optionally extended up to 2kHz if required.
Systems are loaded with a waveform for pre-compliance testing to the volts and interrupts standard EN 61000-4-11. Users can also create their own waveforms and load them into the unit via an SD card.
The high resolution front panel displays a host of measurement functions. These include actual, average and peak values of current, along with true and apparent power, crest factor and cos phi.
Should you only require a single phase output, please see the separate EAC-S product family.
Interfaces and Control
For remote control and automated test systems isolated analogue and computer interfaces are available. Another useful method of control is the external oscillator input. This enables complex waves to be set up on a signal generator and essentially amplified through the EAC-S.
The EAC-3S can also be built with a memory card slot. This enables waveforms to be easily set up on a PC using WAV files. Once transferred using an SD card the waveforms can be stored and recalled from within the AC Source. An optional
±10V input allows a signal from an external waveform generator to be amplified.
Test applications include powering equipment which requires a revolving magnetic field and AC motors.
