TDK Lambda unveils Genesys+ 1U programmable DC power supply series

The first model in the TDK-Lambda Genesys+ series of high power density programmable DC power supplies is the 5kW, 1U model. It uses digital signal processing (DSP) to improve performance and can be used in a range of markets, including component, aerospace and automotive testing, semiconductor fabrication, water treatment, plating and solar array simulation.

Housed in a 1U high, 19-inch (483mm) wide rack package, the 5kW model weighs less than 7kg, making it the lightest in the industry, boast TDK-Lambda/

There are five voltage models of the Genesys+ 5kW available initially. They are 0 to 10V/500A, 0 to 20V/250A, 0 to 30V/170A, 0 to 300V/17A and 0 to 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 265V AC, 342 to 460V AC or wide range 342 to 528V AC inputs, with active power factor correction (PFC). Operating efficiencies are up to 93 per cent.

The Genesys+ doubles the power density of the existing Genesys 5kW 2U series, and also includes a high contrast, wide viewing angle liquid crystal display (LCD) with user controllable brightness and dimming functions. There is faster up and down programming response times, 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.

Another enhancement is the advanced parallel master/slave system. It allows a multi power supply 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 Genesys+ is compatible with both the TDK-Lambda Genesys and Z+ models, and use 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 RS232/485 communications interfaces, which are provided as standard (SCPI compliant). An isolated analogue control and monitoring interface (0 to 5V or 0 to 10V scale) is also provided. An optional GPIB (IEEE488) is available.

The Anybus CompactCom interface platform future proofs the supply to enable various interface options (for example, Devicenet, Ethercat, Modbus and Profibus) as they are introduced. A package of software drivers, waveform creator and virtual front panel GUI is provided.
