OverviewThe EA-ELR 12000-40 4U is a programmable regenerative DC electronic load for comprehensive testing of DC power sources. It combines advanced arbitrary waveform generation, multiple operating modes and high-efficiency energy recovery for laboratory, R&D and production environments.
Key features- Built-in arbitrary waveform generator: sine, triangle, rectangle, trapezoid, DIN 40839, arbitrary, ramp, and IU table functions.
- Dedicated battery charge/discharge and solar PV MPP test modes.
- Scalable master–slave operation with parallelization for larger systems and automatic current sharing.
- Operating modes: constant voltage (CV), constant current (CC), constant power (CP), constant resistance (CR) and autoranging U/I/P.
- Comprehensive protections: overvoltage, overcurrent, overpower, overtemperature, and power-fail.
- Flexible cooling: standard forced-air with optional water-cooling variant for demanding environments.
