TDK Corp. has added high voltage models to TDK-Lambda's Z+ series of 200 W and 400 W programmable DC power supplies. The series is now available with output voltages of up to 160, 320, or 650 Vdc, extending the line-up from 100VDC maximum. These higher voltages address the requirements for applications such as deposition processes, remotely operated underwater vehicles, ATE systems as well as general laboratory and industrial use.
Carrying a 5-year warranty, the TDK-Lambda Z+ high voltage models have the same features and compact dimensions (2U high and 2.76" wide) as the existing models and achieve efficiencies of up to 86%. The units can operate in either constant current or constant voltage modes and accept a universal 85-265 Vac input. Up to 6 units can be connected in parallel (master-slave configuration), or 2 identical units in series with external diodes.
All models can be programmed via the front panel controls or remotely using the USB, RS232/485 or analog control interfaces. Optional LAN, GPIB (IEEE488) and isolated analog programming interfaces are also available.
CE marked for the EMC, Low Voltage, and RoHS Directives, the Z+ series conforms to EN55022/EN55024 as well as IEC/EN61326-1 for conducted (FCC part-15-B) and radiated (FCC part-15-A) EMI. Safety certifications include UL/EN/IEC61010-1 and the series is designed to meet UL/EN60950-1.
