New generation 1U programmable DC power supply series addresses a very broad market

01-06-2017 | Global | Power

TDK Corporation has introduced the TDK-Lambda Genesys+ series of high power density programmable DC power supplies - the 5kW, 1U model is the first in the series. Utilising DSP technology, these next-generation units provide improved efficiency, performance and functionality over existing products available on the market at a competitive cost. The series addresses a very broad market, including component, aerospace and automotive testing, semiconductor fabrication, water treatment, plating and solar array simulation.

Housed in a 1U high, 19” (483mm) wide rack package, the 5kW model offers the highest power density and, at less than 7kg, lightest weight in the industry (less than half the weight of comparable products). Five voltage models are available initially: 0-10V/500A, 0-20V/250A, 0-30V/170A, 0-300V/17A and 0-600V/8.5A. The units can operate in constant current, constant voltage or constant power modes and offer internal resistance simulation. They can accept three-phase 170 to 265VAC, 342 to 460VAC or wide range 342VAC to 528VAC inputs, with active Power Factor Correction. Operating efficiencies are up to 93%.

In addition to doubling the power density over the existing Genesys 5kW 2U series, the device offers many other significant advancements. These include a high contrast, wide viewing angle LCD display with user controllable brightness and dimming functions for improved readability and display life. Faster up and down programming response times speed up operation with user adjustable voltage and current slew rate control. Two user programmable output control pins (open drain) are available to activate external devices, such as load disconnect relays. Arbitrary waveform profiles, such as car battery simulation at vehicle start up, of up to 100 steps can be generated. These are stored in four memory cells and activated by commands from the communication ports or the front panel controls.

Safety certifications include IEC/EN/UL 60950-1 with CE marking for the EMC, LV (low voltage) and RoHS Directives. The series conforms to the industrial environment IEC/EN61326-1 standard for conducted EMI, radiated EMI and EMC immunity.
