DCenergy recoveryhigh-power

Overview

The EA-ELR 12000-20 3U is a high-voltage programmable DC electronic load with energy-recovery capability, engineered for demanding testing of power sources, inverters and high-power components. It supports dynamic and static load simulations while reducing operating costs by returning recovered energy to the local grid. Rack-mountable (3U, 19" form factor) for integration into test systems.

Key features

• Energy recovery: Recovers energy from the load and feeds it back into the local grid to reduce operating costs and heat dissipation.
• Flexible operating modes: Supports constant voltage (CV), constant current (CC), constant power (CP) and constant resistance (CR) modes and U/I/P autoranging for dynamic and static load simulations.
• Comprehensive protections: Built-in safeguards (OVP, OCP, OPP) to protect the unit and the device under test.
• User interface & control: Color TFT touchscreen with rotary knobs for local operation; remote control and data logging via analogue 0–5 V / 0–10 V, USB, LAN (Ethernet), Profibus, DeviceNet, RS232, CAN and Modbus.
• Scalable operation: Master-slave parallel operation for building larger test systems (up to 64 units in parallel).

Applications

• Photovoltaic inverter testing
• Electric vehicle (EV) power system validation
• High-power component ageing and reliability testing
