New 1U high 7,500W programmable power supply series

Initially, six models will be available capable of providing outputs from 0 to 20V at 375A through to 0 to 1,500V at 5A. The output power of the product enables system configurators to avoid the need to parallel lower wattage power supplies, reducing the rack or cabinet size. The series benefits from DSP (Digital Signal Processing) technology and the latest generation components, including ferrite materials, to obtain efficiencies of 91 to 92%. Less internal waste heat ensures a higher power rating without compromising reliability.

Target applications for the 7,500W power supplies are automotive testing - including electric and hybrid cars, general test or research, measurement, semiconductor fabrication, battery manufacturing, and renewable energy.

The first six voltage models to be available are 0-20V/375A, 0-40V/188A, 0-100V/75A, 0-150V/50A, 0-600V/12.5A and 0-1500V/5A. The units can operate in constant current, constant voltage, or constant power limit modes and in addition offer internal resistance simulation. The units can be specified to accept three-phase 170 to 265Vac or wide range 342 to 528Vac inputs, with active Power Factor Correction. Operating efficiencies are up to 92%.

The GENESYS+ 7.5kW is suitable for zero stack rack mounting, measuring 423mm width, 486.5mm deep and 43.6mm (1U) high. Cooling is provided by variable speed fans that monitor the ambient temperature and the output load. The weight of the unit is less than 8.5kg for easy handling.

All models in the GENESYS+ series have a high contrast, wide viewing angle LCD display with user controllable brightness and dimming functions, and faster up and down programming response times, with user adjustable voltage and current slew rate control. Arbitrary waveform test profiles of up to 100 steps can be generated and stored in four memory cells and activated by commands from the communication ports or the front panel controls.

For additional power, the 7,500W power supplies use TDK-Lambda’s advanced parallel system (patent pending) allowing a multiple unit system to achieve a dynamic response and ripple and noise performance comparable to that of a single power supply. Up to 12 GENESYS+ units can be connected in parallel very simply by connecting a single data link cable between units and connecting the dc outputs in parallel. The command and auxiliary units auto-configure by detecting the parallel data connection and set their parameters accordingly.

Programming is consistent across the entire 1kW to 60kW GENESYS+ series by either front panel controls, remotely via LAN (LXI 1.5), USB 2.0, and RS232/485 communications, or by using the isolated analogue control and monitoring (0-5V, 0-10V), which are provided as standard. Optional interfaces include a choice of EtherCAT or Modbus-TCP or GPIB (IEEE488.2). Software drivers, a waveform creator and a virtual front panel GUI are provided in the software package. Safety features are standard in all GENESYS+ power supplies, providing Safe/Auto Re-Start, Last Setting Memory, and built-in protection functions.

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