TDK Corporation has introduced new high voltage units within the TDK-Lambda Z+ Series of 200W and 400W programmable DC power supplies. The Z+ high voltage series is offered with output voltages of up to 160, 320 or 650Vdc extending the line-up from 100Vac maximum. These higher voltages address the requirements for applications such as deposition processes, ROVs, ATE systems as well as general laboratory and industrial use.
With a 5-year warranty the series shares the same features and compact dimensions as the other Z+ ranges and achieves efficiencies of up to 86%. The units can operate in either constant current or constant voltage modes and accept a universal (85-265Vac) input. Higher power systems can be achieved by connecting up to 6 units in parallel in master-slave configuration. To increase the output voltage or to provide a bipolar output, up to 2 identical units may be connected in series with external diodes.
All models can be programmed via the front panel or remotely by using the built-in USB, RS232 / RS485 or analogue control interfaces. Optional LAN, GPIB (IEEE488) and isolated analogue programming interfaces are also available.
CE marked for EMC and in accordance with the LV (low voltage) and RoHS Directives, the Z+ high voltage series conforms to EN55022/EN55024, as well as IEC/EN61326-1 for conducted (FCC part-15-B and VCCI-B) and radiated (FCC part-15-A and VCCI-A) EMI. Safety approvals include UL/EN/IEC61010-1, and the Z+ high voltage series is designed to meet UL/EN60950-1.
