Programmable power supplies output up to 500A

December 15, 2015 // By Graham Prophet
TDK Corporation has three additional in its TDK-Lambda’s Genesys series of programmable DC power supplies, providing outputs of 30V at 500A, 40V at 375A and 50V at 300A and output powers of 15 kW.

These higher current units address the requirements for applications in the OEM, Industrial, Aerospace and ATE markets including semiconductor and automotive test, component test/burn-in and magnet supplies.

The high current models have the same features and compact dimensions (3U high and 19 in. (483mm) wide) as the existing 60V to 600V 15 kW models. The units can operate in either constant current or constant voltage mode and accept three-phase 400 VAC or 480 VAC inputs, with passive power factor correction.

Higher power systems can be configured using the Master/Slave “Advanced” Parallel operating mode. This mode configures the Master unit to be the single point for programming, measurement and status of the total current of the paralleled system. Four units can operate as a single 60 kW power supply.

Common to the entire Genesys family is the embedded 16-bit RS-232/RS-485 Multi-Drop digital interface. Using this digital interface, up to 31 power supplies may be controlled in a daisy-chain over the RS-485 communication line.

Other optional digital and analogue interfaces include the LXI Class C compliant LAN and the IEEE (IEEE488.2 and SCPI-compliant) Multi-Drop digital interfaces, which include a selection of instrument drivers such as NI LabVIEW and NI LabWindows. Isolated analogue programming/monitor interface options included use either 0-5V/0-10V or 4-20 mA control. Safety features included are Safe/Auto Re-Start, Last Setting Memory and built-in protective functions.

CE marked in accordance with the Low Voltage Directive, the GenesysTM 3U 15kW power supply series conforms to conducted and radiated EMI in accordance with EN55011A and FCC Part 15J-A. Safety agency certifications include UL60950-1 and EN60950-1.
