This unit achieves efficiencies up to 89% and carries a 5-year warranty. All units in the Z+ range can operate in either constant current or constant voltage modes and accept a universal (85-265 Vac) input. For higher power systems, such as those used in test or simulation applications, up to six units can be connected in parallel in a master-slave configuration. To increase the output voltage or to provide a bipolar output, 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. CE marked for EMC and in accordance with the LV (low voltage) and RoHS Directives, the Z+ high voltage series conforms 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.
