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.

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. Besides bench or laboratory units, our DC sources can be rackmounted or built as an ATE system controlled via a remote control interface. Modular designs are available which are easily expandable.

DC Electronic Loads

DC electronic loads mimic the real world operating conditions for a variety of applications. Each unit can be built with analogue and computer interfaces to allow remote operation. LabVIEW drivers are also available for most product families to simplify integration into wider test systems. A comprehensive mix of voltage and current sink ranges are possible. Common operating features include OVP/OCP tests, front panel memory as well as CC, CV, CR and CP modes. In dynamic mode rise, fall and plateau times are adjustable. Grid-tied power recycling loads are available.
