Programmable power supplies

18 March 2015 Power Electronics / Power Management

An 800 W model has been added to the TDK-Lambda Z+ series of high-voltage programmable DC power supplies. As with the 200 W and 400 W models, it is offered with output voltages of up to 160, 320 or 650 V d.c. (as well as an additional model offering up to 375 V d.c.), addressing the requirements for applications such as deposition processes, ROVs, ATE systems as well as general laboratory and industrial use.

Sharing the same features and compact dimensions as the other Z+ ranges, the new model achieves efficiencies up to 89% and carries a five-year warranty. All units in the range can operate in either constant current or constant voltage modes and accept a universal (85–265 V a.c.) input.

For higher-power systems, such as those used in test or simulation applications, up to six units can be connected in parallel in a master-slave configuration. To increase the output voltage or to provide a bipolar output, up to two identical units may be connected in series with external diodes. All models can be programmed via the front panel or remotely via USB, RS-232/RS-485 or analog control interfaces. Optional LAN, GPIB (IEEE488) and isolated analog programming interfaces are also available.
