Programmable DC power supplies
14 November 2018, Power Electronics / Power Management

TDK announced the addition of high-power GSP models to the TDK Lambda GENESYS+ series of programmable DC power supplies. This expansion now provides 2U high, 10 kW and 3U high, 15 kW versions with output voltages and currents of up to 0-10 V/1500 A to 0-600 V/25,5 A. The GENESYS+ series addresses a very broad market, including component, aerospace and automotive testing, semiconductor fabrication, water treatment, plating and solar array simulation.

Utilising DSP (digital signal processing) technology, these next-generation units provide improved efficiency, performance and functionality over existing products, with efficiencies of up to 92%. The 20 new high-power models can be programmed to operate in constant voltage, constant current or constant power modes, and also offer the ability to simulate an internal resistance for battery charging and long output cable voltage drop applications. The units are available for use with three-phase 170 to 265 V a.c., 342 to 460 V a.c. or 342 to 528 V a.c. inputs.

All GENESYS+ models feature an easy to read LCD display with user controllable brightness and dimming functions for extended life. Additionally, they include faster up and down programming response times with user adjustable voltage and current slew rate control. The provision of two user programmable output open drain control pins can be used to activate external devices like load disconnect relays.

Arbitrary waveform profiles, such as car battery simulation at vehicle startup, 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 programs.

All functions can be programmed via the front panel or remotely using the LAN (LXI 1.5), USB 2.0 or RS-232/485 communications interfaces, which are provided as standard (SCPI compliant). An isolated analog control and monitoring interface (0-5 V or 0-10 V scale) is also included.

The product design includes options for GPIB (IEEE488.2) and the Anybus CompactCom interface platform for DeviceNet, EtherCat, Modbus, Profibus and other interface options as they are released. A full package of software drivers, a waveform creator and a virtual front panel GUI are provided in the software package.

Safety features include safe/auto restart, last setting memory and built-in protective functions. With safe-start configured, the power supply will return to its last operational settings after a power interruption but with the output disabled. With auto restart, the power supply returns to the last used operation settings after a power interruption where no user intervention is preferred.

Last setting memory retains settings such as the output voltage/current, output on/off, OVP/UVL level, fold-back and startup mode at each AC input turn-off sequence, even after extended periods of storage or non-use. Built-in protective functions include over-voltage protection (OVP), under-voltage limit (UVL), fold-back protection (FOLD) and over-temperature protection (OTP).

The five-year warranty series is safety certified to IEC/EN/UL 60950-1, CE marked to the Low Voltage, EMC and RoHS2 directives, and conforms to the industrial IEC/EN 61326 1 standard for conducted EMI, radiated EMI and EMC immunity.
