Programmable DC power supply

13 June 2018 Power Electronics / Power Management

The Genesys+ series of high-power-density programmable DC power supplies from TDK-Lambda includes a 5 kW model with 1U rack height.

Utilising digital signal processing technology, these units address a very broad market, including component, aerospace and automotive testing, semiconductor fabrication, water treatment, plating and solar array simulation.

Housed in a 19” (483 mm) wide rack package, the 5 kW model offers high power density and weighs less than 7 kg. Five voltage models are available: 0-10 V/ 500 A, 0-20 V/ 250 A, 0-30 V/ 170 A, 0-300 V/ 17 A and 0-600 V/ 8,5 A. 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 265 V a.c., 342 to 460 V a.c. or wide range 342 to 528 V a.c. inputs, with active power factor correction. Operating efficiencies are up to 93%.

In addition to doubling the power density over the Genesys 5 kW 2U series, Genesys+ offers advancements such as 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 startup, 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.

A parallel master/slave system allows a multi-PSU system to achieve dynamic response and ripple and noise performance comparable to that of a single power supply. Up to four Genesys+ units can be connected in parallel very simply by connecting a single data link cable between units and connecting the DC outputs in parallel. The master and slave units auto-configure by detecting the parallel data connection and set their parameters accordingly. The master unit becomes the single point for programming, measurement and status of the total current of the paralleled system.

The product range is compatible with both the TDK-Lambda Genesys and Z+ models, using the same communication protocols and signals. 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 provided, and an optional GPIB (IEEE488) is available.

The Genesys+ design incorporates the Anybus CompactCom interface platform to enable various interface options as they are introduced, e.g. Devicenet, Ethercat, Modbus and Profibus. A full package of software drivers, waveform creator and virtual front panel GUI is provided.

Safety features include safe/auto restart and last setting memory, and built-in protective functions such as over-voltage protection, under-voltage, fold-back protection and over-temperature protection. The series conforms to the industrial environment IEC/EN61326-1 standard for conducted EMI, radiated EMI and EMC immunity.
