Bidirectional power supply simplifies EV powertrain testing

Compliant with both LV123 and LV148 standards for EV component testing, the 62000D has a fast cross-quadrant bandwidth that produces a rapid transient response time (as short as 1.5ms or less). A wide range of voltage and current combinations are available in constant power mode, and constant current and constant voltage modes are also available. Across the range, the maximum power that can be catered for is from 6kW to 18kW, with what MDL claims is an industry-leading power density of 18kW within a 3U rack height. Output current ratings are up to +/-540A, with voltage ratings up to 1800V DC. When greater power is required, master/slave capability enables up to ten of the units to operate in parallel to deliver up to 180kW.

Icons on the intuitive touch screen make it easy to carry out voltage/current settings and measurements, as well as programme the auto sequence control settings, and preview output waveforms. One hundred programmable user settings are available in the units' list mode and control interface options include USB, LAN, CANbus and GPIB as well as analogue APG.

In addition to the EV and HEV sector, the units could also have applications in renewable energy systems such as home energy storage, as well as in the development of motors, drives, inverters, batteries, fuel cells, etc.
