Programmable power supplies in 90kW rated GSPS 20U 19" racking cabinets

TDK Corporation has introduced its 90kW-rated GSPS 20U 19" racking cabinets to the TDK-Lambda GENESYS+ series of programmable DC power supplies. The GSPS systems seamlessly transition across constant voltage, constant current and constant power limit operating modes. The cabinets are mounted on lockable castors to allow them to be easily repositioned around research or production facilities.

The series satisfies the demands of testing and measurement of automotive components, batteries for EVs, aerospace, high-power magnets, medical imaging, semiconductor processing, and industrial automation and process control applications.

Internally, 12 of the GENESYS+ 7.5kW power supplies are configured together to provide 12 output voltage ranges from 0-20V to 0-1500V with output currents of up to 4500A. The company's patented advanced parallel system delivers dynamic load response and ripple and noise characteristics comparable with that of a single power supply.

The input voltage range is three-phase 342VAC to 528VAC 47-63Hz, covering nominal 380, 400, 415, 440, 460 and 480VAC. The input circuit breakers are accessible on the cabinet's front panel, and the paralleled output bus bar connections are at the rear. Safety features are standard in all GENESYS+ power supplies, providing Safe/Auto Re-Start, Last Setting Memory and built-in protection functions for voltage, current and temperature.

The series uses common programming across the entire GENESYS+ series, either by the front panel controls, remotely via LAN (LXI 1.5), USB 2.0 and RS232/485 communications or an isolated analogue control and monitoring interface (0-5V, 0-10V), which are provided as standard. Optional interfaces include a selection of GPIB (IEEE488.2), EtherCAT, Modbus-TCP and IS420 (4mA to 20mA isolated current programming loop). The software package provides drivers, a waveform creator, and a virtual front panel GUI.

The racking cabinet measures 553mm x 902mm x 1028mm (WxDxH) and weighs less than 200kg. The castors can be removed if not required.

The five-year warranty series is safety certified to IEC/EN/UL 61010-1 and has CE and UKCA markings for the Low Voltage, EMC, and RoHS Directives. The series also complies with IEC/EN 61204-3 for conducted and radiated EMI and EMC immunity.
