Programmable power supplies now rated to 800W

May 21, 2013 // By Graham Prophet
TDK has added to its Z+ Series of PSUs with higher power units for standalone or system applications, that can be 2U rack mounted

TDK-Lambda's Z+ Series of programmable DC power supplies is extended with the higher power Z+800 range. These 800W programmable power supplies offer the same features as the lower power Z+400 and Z+200 ranges and address the need for high quality bench-top power supplies for the R&D environment. The TDK-Lambda Z+800 range shares the same package size as the Z+200 and Z+400 and thus offers extremely high power density. It is also suited for ATE and OEM 2U rack mounted or integrated applications such as test & measurement, semiconductor burn-in, component test, laser diode, heater supplies, RF amplifiers and electromagnets.

Models in the 800W Z+ Series are available with output voltages up to 100 Vdc and output currents up to 72A. The Z+800 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 six identical units in parallel with active current sharing. To increase the output voltage or to provide a bipolar output, two units may be connected in series.

All models can be programmed via the front panel or remotely using USB, RS232/485 and analogue interfaces which are built in as standard. Optional LAN, GPIB (IEEE488) and isolated analogue programming interfaces are available. CE marked in accordance with the Low Voltage Directive, the Z+800 conforms to EN55022-B, FCC part-15-B and VCCI-B for conducted and radiated EMI. Safety approvals include UL/EN/IEC61010-1, and the Z+800 is designed to meet UL/EN60950-1.
