PCR-WE/WE2 series

Ultra-Compact AC/DC Programmable Power Supply

Application of Regenerative AC, DC, AC+DC Power Supply

● Testing AC Bus connected equipment 115V / 230V (one-Phase) 200V / 400V (three-Phase) 400Hz, 360Hz to 800Hz, up to 5kHz

The PCR-WE2 series is adaptable with both buses and can be used as a power source for development and evaluation tests. The three outputs can be set independently so that di�erent voltage combinations (including AC and DC combinations) are possible.

● Testing DC Bus connected equipment HVDC 270V / ±270V (540V) DC 28V

Test System Solutions for Bi-Directional ConvertersAs development of More Electric Aircraft(MEA) has increased, it has become essentialto convert both buses to converters.This article presents the best power supply for testing bi-directional AC/DC connected between AC bus and HVDC bus as an example.

Conventional AC power supplies unable tosink, requiring a resistive load and anelectronic load device to be connected inparallel. In addition, since these load devicesconvert the absorbed energy into heat, itcreates problems treating the heat exhaust.In the Regenerative AC Power Supply solution, the source and sink can be covered by a single power source. In addition to reducing equipment installation space, energy is not processed as heat, but regenerated to the grid, creating an environmentally friendly test system.
