TDK-Lambda: six new output configurations for the 7.5kW GENESYS+ series 

TDK Corporation announces the introduction of six new models to the 7.5kW TDK-Lambda GENESYS+ series of high power density programmable DC power supplies. This expansion now provides incremental and seamless choices in output voltage and current ranging from 0-20V/375A to 0-1500V/5A. Target applications for the 7.5kW power supplies are automotive testing – including electric and hybrid cars, general test or research, measurement, semiconductor fabrication, battery manufacturing, and renewable energy.

The six new voltage models offer 0-30V/250A, 0-60V/125A, 0-80V/94A, 0-200V/37.5A, 0-300V/25A and 0-1000V/7.5A. 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 7.5kW output power 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.

For additional power, the 7.5kW programmable 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. The command and auxiliary units auto-configure by detecting the parallel data connection and setting their parameters accordingly.
