TDK Corporation announces that 600W models have been added to its TDK-Lambda Z+ Series of programmable DC power supplies. Complementing the Z+200, Z+400 and Z+800 ranges, these 600W programmable power supplies offer the same superior features and carry a 5-year warranty. Addressing the need for high quality bench-top power supplies for the R&D environment, the new range shares the same dimensions as the other Z+ ranges and thus offers high power density. The range 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 this series are available with output voltages up to 100Vdc and output currents up to 60A. The Z+600 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 6 identical units in parallel with active current sharing. To increase the output voltage or to provide a bipolar output, up to 2 units may be connected in series.
