What It Is + Why It Matters

High-current regenerative electronic load – sinks DC power and feeds back up to 94.5% of absorbed energy to the grid, reducing cooling and electricity costs.
Wide current range 0-210A perfect for high-capacity battery discharge, fuel cell loading, and power supply burn-in.
Built-in function generator with sine, triangle, rectangular, trapezoid, arbitrary (99 points), ramp, DIN 40839, plus battery test (static/dynamic discharge) and MPPT tracking (4 modes).
Internal resistance simulation (CR mode) for realistic battery and fuel cell loading.
Master-Slave parallel – up to 64 units for 960kW total system power; true current sharing via Share bus and digital MS bus.
High dynamics: Current rise time ≤2ms (10-90%).

Note: Remote sensing compensates up to 5% of U_Nom. Always use DC terminal covers. Check local regulations for grid feed-in (grid protection device may be required).

Best for / Not for

Best for: High-current battery discharge testing (EV modules, lead-acid banks), fuel cell stack loading, DC power supply burn-in, solar panel MPPT characterization, and industrial ATE requiring up to 200V/210A.
Not for: Series connection of multiple loads (not permitted); source operation (power supply only); applications requiring output above 200V (use higher voltage ELR models).

Selection Checklist + Integration

Confirm source voltage ≤200V DC and current ≤210A (peak 15000W). Note derating on 208V AC input to 9000W.
DC cable cross-section: For 210A, use at least 95mm² (AWG4/0) per pole; use ring lugs (M8 bolt for Type 1 terminal).
Mounting: 19" rack, 3U height, allow >30cm rear clearance for airflow.
For master-slave parallel: Connect Share bus (BNC) and MS bus (RJ45 CAT5); terminate ends via internal settings (BIAS/TERM). Up to 64 units.
For energy recovery: Ensure grid connection can accept regenerated power; may require external grid protection device per local regulations (e.g., VDE-AR-N 4105).
For battery test: Use built-in static or dynamic discharge mode with adjustable discharge voltage, time, and capacity thresholds.
For MPPT tracking: Select mode MPP1 (find MPP), MPP2 (track), MPP3 (fast track), or MPP4 (user-defined curve via USB).
For remote sensing: Use supplied sense connector to compensate voltage drop; do not connect NC pins (200V model has no NC restriction).
Firmware updates via USB-B and EA Power Control software (included).
