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 100 Vdc 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 in. 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.
