June 23, 2014. TDK Corp. has announced the introduction of high-voltage models in the TDK-Lambda 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, and 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- to 265-VAC input. Up to six units can be connected in parallel (master-slave configuration), or two identical units can be connected 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 (IEEE 488), 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.
