High voltage power supplies are programmable
The 200 and 400W programmable DC power supplies offer output voltages of up to 160, 320 or 650V DC extending the line-up from 100V AC maximum. They are targeted at applications requiring higher voltages such as deposition processes, ROVs, ATE systems as well as general laboratory and industrial use. Carrying a five-year warranty, they share the same features and compact dimensions as the other Z ranges and achieves efficiencies of up to 86%. The units can operate in either constant current or constant voltage modes and accept a universal (85 to -265V AC) input. Higher power systems can be achieved by connecting up to six units in parallel in master-slave configuration. To increase the output voltage or to provide a bipolar output, up to two identical units may be connected in series with external diodes. All models can be programmed via the front panel or remotely by using the built-in USB, RS232 / RS485 or analogue control interfaces. Optional LAN, GPIB (IEEE488) and isolated analogue programming interfaces are also available. They are CE marked for EMC and in accordance with the LV (low voltage) and RoHS Directives and conform to EN55022/EN55024, as well as IEC/EN61326-1 for conducted (FCC part-15-B and VCCI-B) and radiated (FCC part-15-A and VCCI-A) EMI. Safety approvals include UL/EN/IEC61010-1, and the Z high voltage series is designed to meet UL/EN60950-1.
