  • AC Power Sources

    An AC source can simulate all mains/line voltages during R&D and production testing. We offer both electronic and motor driven power supplies. Units are available with either single or three phase outputs. Common waveforms are pre-installed, with the ability to edit voltage and current parameters.

    Popular features include variable frequency, adjustable phase angle, programmable ripple and constant current. A wide choice of analogue and computer interfaces can be fitted for system integrations. Fixed output values are possible if the unit is required to act as a simple converter.

  • DC Sources

    ETPS provide one of the most comprehensive selections of programmable DC sources on the market. Virtually any power, voltage or current requirement can be met. Adjustable power and resistance limits are offered in addition to standard CC and CV operation.

    Both switch mode and linear power supplies are present within the range. Bipolar and bidirectional sink/source systems with optional mains recycling are also available. Besides bench or laboratory units, our DC sources can be rackmounted or built as an ATE system controlled via a remote control interface.

  • DC Sources over 40kW

    Our high power DC power supplies include programmable units for laboratory and heavy industrial applications. High currents of up to 50kA and nominal powers up to 3MW are possible.

    The high power range has been designed with precision and efficiency in mind. Compact systems are our speciality. For example, 90kW is possible in just 18U of rack space. Modular designs are available providing flexible and future proofed systems, as they can be easily reconfigured or expanded.

  • AC Electronic Loads

    Each AC load is installed with a bank of 55 common waveforms, containing crest factor variations which replicate high current peaks. Adjustable power factor enables leading and lagging current down to 0.3.

    Power sinks are available from 300W to over 10kW. A dedicated DC mode is provided as standard, allowing for the loading of DC devices, thus saving lab space. By using the dynamic function, constant voltage and constant power sinking can be achieved. Power recycling AC loads are available on request.

  • Custom Units

    ETPS have a long history of providing modified and bespoke power systems. We can often design an exact system, using one of our standard AC or DC products as a basis. Output values, ramp profiles, voltage polarity, input range and response times can all be tailored to suit specific test and development needs.

    Besides altering electrical characteristics, mechanical modifications can be made to protect against shock, vibration and humidity. Units can also be treated to full flight case and lab rack integrations on request.

  • Bidirectional DC

    Bidirectional power systems can operate as either a DC source or load. This integrated approach features high dynamics enabling users to switch quickly between quadrants. Both modular systems and high power cabinets are available.

    When operating as a load each unit has power recycling technology. The inbuilt monitoring system synchronises with the grid and regenerates any excess DC energy back to the three phase mains supply.
