Flexible power concept for laboratory & system applications. The high level of flexibility of the current, voltage & power output parameters extends the application area of this new generation of power supplies the EA-PS 9000 series to an unparalleled extent. Where previously a specific device type with a square voltage/current envelope had to be obtained for each application, now a flexible power concept is employed. An RPM-regulated fan ensures a low-noise operation. The ZH-equipped device to a two-quadrant module for quick & defined discharge of the output voltage (source-sink principle) according to DIN 40839, to be able to use the device in automotive electronics testing stations. Thus, vehicle-to electronics testing can be carried out by simulating the motor characteristic or car hi-fi test.
