EA Elektro-Automatik EA-EL 9750-40 B Programmable Electronic Load 0 to 2400 W, 0/750 V, 0 to 40 A, 3U Rack Unit

EA Elektro-Automatik EA-EL 9750-40 B is a state-of-the-art programmable electronic load from the EA-EL 9000 B Series designed for precise and dynamic testing of DC power sources. It operates over a power range of 0 to 2400 W, voltage range from 0 to 750 V, and current range from 0 to 40 A, housed in a 3U 19" rack unit.

This electronic load is controlled by a high-performance FPGA with 16-bit resolution ensuring accurate load application and measurement suitable for laboratory R&D, industrial test benches, and automated load testing systems. The unit provides constant power, voltage, current, and resistance modes plus battery discharge mode for versatile testing capabilities.

The device features a user-friendly TFT touch panel with a comprehensive menu including function generator waveforms (sinus, square, trapezoidal, ramp, arbitrary), memory storage, alarm management, and user profiles. It visually displays voltage, current, resistance, and power with 4-digit precision.

Connectivity includes Ethernet, USB, and RS232 interfaces with an onboard isolated analog interface (0-5V/0-10V) and plug’n play slots for optional communication protocols like CANopen, Profibus, and Modbus, supporting flexible integration into automated environments.

The DC input stage is highly stable with fully adjustable filters (0 to 100%) providing ripple-free operation and fast dynamic response of 30 microseconds using FET linear technology. This makes it ideal for rigorous testing of power supplies, batteries, and DC sources requiring reproducible and reliable load conditions.

With dimensions of 485 mm width, 133 mm height (3U), and 510 mm depth including terminals, this 19" rack mountable device fits standard test laboratory setups and industrial racks. Its true master-slave parallel operation capability allows stacking multiple units for high power load banks.

Applications include research and development laboratories, industrial manufacturing testing lines, burn-in rooms, telecom power testing, battery charger evaluation, and automated quality control systems.

Provides precise programmable load testing suitable for lab and industrial applications. Features FPGA-controlled 16-bit resolution for high-performance measurement and control. Supports multiple operation modes including constant power, voltage, current, and resistance.

Equipped with Ethernet, USB, and RS232 interfaces for flexible connectivity and automation. Includes a TFT touch panel with intuitive menu and graphical display of electrical values. Incorporates plug’n play slots for optional interface modules such as CANopen and Modbus.

Designed for dynamic and ripple-free DC input with adjustable filtering and fast response (30 μs). Ideal for automated system integration and heavy-duty load bank configurations. Constructed with a 19" 3U rack housing measuring 485 x 133 x 510 mm including terminals.
