Bidirectional laboratory power supply

28 August 2019 Power Electronics / Power Management

EA Elektro-Automatik’s new 30 kW EA-PSB 10000 is a bidirectional power supply with a working efficiency of up to 96%, both as a source and as a drain with energy feedback. The device can be switched from source to drain with no delay.

For example, charging and discharging an energy storage in various power ranges may be carried out with just one device. Energy in the motor testing recuperation phase can be collected directly by the EA-PSB 10000 and fed back to the mains.

The efficiency of the devices leads to a reduction in heat generation, but EA also offers water cooling as an option, with up to 95% of the power loss dissipated through the fluid. The fully digital controls allow remote setting of, for example, customer-specific PID parameters which differ from the factory settings.

In order to fully utilise the performance of the EA-PSB 10000, intuitive control software is provided. With EA Power Control the user can operate up to 20 devices remotely, control additional functions such as sequencing, and use a practical data collection. A further new feature is the battery simulation software. Thus the customer can use the EA-PSB 10000 to test their hardware under practically real conditions.
