EA Elektro-Automatik EA-EL 9000 B Series Electronic Load, 0 → 1200 W, 0 → 750 V, 0 → 20 A

EA-EL 9000B Series 19" 3U conventional electronic loads are adjustable and programmable. They come equipped with a high-performance FPGA (Field Programmable Gate Array) controller with 16-bit resolution.

EA-EL 9000B features include a flexible DC input range for use at high voltage or high current as required, within the nominal power rating. The TFT touch panel has an easy-to-operate intuitive menu structure. This integrates multiple functions such as a function generator with default wave forms (e.g., sinus, square, trapezoidal, ramp, arbitrary), memory, alarm manager and user profiles. It displays U/I/R/P values with 4-digit resolution.

The DC input is highly stable and filtered with 0...100% adjustable parameters, very dynamic (30μs) and generates no ripple (FET linear technology). For external automated control, 9000B models have an on-board isolated 0-5V/0-10V analog and USB interface. An intelligent plug’n play slot allows retrofitting optionally available interface modules such as CANopen, Ethernet, Profibus and Modbus.

EA-EL 9000B is an excellent choice for demanding load testing, to provide for reproducible test data, and is suitable for automated system integration to form heavy-duty load banks.
