TDK has added new high-voltage units to the TDK-Lambda Z+ Series of 200 W and 400 W programmable DC power supplies.
The new series is offered with output voltages of up to 160, 320 or 650 V d.c. extending the lineup from 100 V a.c. maximum. These higher voltages address the requirements for applications such as deposition processes, ROVs, ATE systems as well as general laboratory and industrial use.
Carrying a 5-year warranty, the Z+ high-voltage 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 - 265 V a.c.) input.
Higher-power systems can be achieved by connecting up to six units 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 using the built-in USB, RS-232/RS-485 or analog control interfaces. Optional LAN, GPIB (IEEE488) and isolated analog programming interfaces are also available. CE marked for EMC and in accordance with the LV (low voltage) and RoHS directives, the power suppllies conform 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.
