New generation of programmable power supplies with high power density

Within about a year, TDK Corporation rolled out the new generation of its programmable power supply series TDK-Lambda GENESYS+™ and once again set new standards. In particular, the introduction of state-of-the-art DSP technologies (Digital Signal Processing) offers many new possibilities that the new GENESYS+™ power supplies translate into practical user benefits, such as doubling power density through higher efficiency (up to 92 percent), new functions such as arbitrary generator, internal resistance simulation, an improved, adjustable display, improved control behavior and an unparalleled price/performance ratio.
Housed in a 1U high, 19” (483 mm) wide rack housing, the 5 kW model offers the highest power density and weighs just 7.5 kg, the lightest in the industry. Ten voltage models are available rated at 0-10 V / 500 A, 0-20 V / 250 A, 0-30 V / 170 A, 0-40 V / 125 A, 0-60 V / 85 A, 0-80 V / 65 A, 0-100 / 50 A, 0-150 V / 34 A, 0-300 V / 17 A and 0-600 V / 8.5 A. They are offered with three-phase 170 to 265 Vac, 342 to 460 Vac or wide range 342 to 528 Vac inputs, and all feature active Power Factor Correction.

The 1.7 kW 1U model, weighing only 5 kg, has been specifically developed with lower power applications in mind, such as use in research laboratories, and operates from a single-phase wide range AC input of 85 to 265 Vac. Output voltage ratings are similar to the 5 kW model, with versions ranging from 0-10 V to 0-600 V and supporting output currents from 0 - 2.8 A to 0 – 170 A. The GENESYS+™ GSP models address higher power levels, providing 10 kW in 2U and 15 kW in 3U form factors with output voltages and currents from 0-10 V/1,500 A to 0-600 V/25.5 A.

Powerful Digital Signal Processing

Utilising DSP technology, these next-generation GENESYS+™ units provide improved efficiency, performance and functionality over existing Genesys™ products, with efficiencies of up to 92 per cent. All models can operate in constant voltage and constant current modes with automatic crossover and have an independently variable constant power limit.
A variable internal resistance function is provided to simulate battery behavior or voltage drop on long output cable runs. Arbitrary waveform profiles, for example car battery output voltage profile simulation at vehicle start up, of up to 100 steps can be generated and stored in four memory cells. These can be activated by commands from the communication ports or the front panel controls, allowing the user to quickly switch between programmes.
