30-Second Fit Check

Need to sink 30 kW of DC power while recovering energy? Models span 0‑80 V up to 0‑2000 V and up to 1000 A, feeding up to 96.5% of absorbed power back to the grid.
Four regulation modes: Constant Voltage (CV), Constant Current (CC), Constant Power (CP), Constant Resistance (CR) – with selectable dynamic response (Slow/Normal/Fast).
Comprehensive protection: Overvoltage (OVP), Overcurrent (OCP), Overpower (OPP), Overtemperature (OT), Share Bus Fail (SF).
A built‑in function generator (sine, triangle, square, trapezoid, DIN 40839, arbitrary 99‑point, ramp, XY table) enables dynamic load profiling without extra equipment.
Optional water cooling reduces audible noise and heat dissipation into the environment; remote control via galvanically isolated analog (0‑5/10 V), USB, Ethernet, and optional fieldbus modules.

What It Is + Why It Matters

Regenerative, energy‑recovering DC electronic loads for industrial test systems, battery pack discharge, solar inverter MPPT validation, and heavy‑duty DC source burn‑in.
Integrated battery test function with static/dynamic modes, configurable stop conditions (voltage, Ah, time) and dedicated logging – ideal for capacity and endurance testing.
MPP tracking (modes 1‑4) for solar inverter testing, including user‑definable curve tracking (100 points) and automatic result data export.
True master‑slave parallel operation supports up to 64 units, totaling 1920 kW, with automatic current sharing via the Share bus.

Note: The recuperation feature requires a stable grid connection; consult local regulations and install a grid protection device if feeding into the public grid. Always confirm the minimum input voltage for maximum current (varies by model).

Key Specs

AC input: 380‑480 V, 3ph (208 V with derating to 18 kW), 45‑65 Hz, power factor ~0.99.
Load regulation: ≤0.05% FS (CV), ≤0.1% FS (CC); stability: ≤0.02% FS over 8 h.
Rise time (10‑90% CC): ≤2 ms; display accuracy: 0.05% (V), 0.1% (I).
Interfaces: 1x USB‑B, 1x Ethernet (100 Mbit), 1x USB‑A (host), 1x 15‑pin D‑Sub analog; slot for optional fieldbus modules.
Remote sensing compensation: up to 5% of nominal voltage; digital master‑slave bus via dual RJ45.
Dimensions: 4U 19‑inch rack chassis; weight varies by model. Water‑cooled versions available.

Integration & Installation

DC input via copper blade terminals with M10 (up to 200 V) or M6 (≥360 V) bolts; use ring lugs or copper bars for low inductance.
AC input via a 5‑pole plug (3x L + PE, N optional); included strain relief and separate grounding point for additional PE connection.
USB stick slot (front) for data logging, arbitrary waveform save/load, and profile export/import (FAT32, up to 32 GB).
Voltage controller speed selectable (Slow/Normal/Fast) to match source characteristics and prevent oscillation; external capacitance may be added for stability (see manual).

Best for / Not for

Best for: High‑power battery pack discharge testing, solar inverter MPPT efficiency profiling, industrial DC power supply burn‑in, fuel cell testing, and applications where recovered energy can be reused within the local grid.
Not for: Series connection of loads (not permissible); operation without proper grid protection when feeding back into public mains; use with extreme inductive sources without additional stabilization capacitance.

Selection Checklist + RFQ

Choose voltage/current model matching your test requirements (80V, 200V, 360V, 500V, 750V, 920V, 1000V, 1500V, or 2000V; and 40A, 60A, 80A, 120A, 125A, 180A, 240A, 420A, or 1000A).
Confirm AC supply: 400 V or 208 V (derated power 18 kW).
Select cooling: standard air cooling or optional water cooling (lower noise, no waste heat into room).
Specify needed interfaces (analog, Ethernet, USB) and optional fieldbus module (CAN, Profibus, EtherCAT, etc.).
Plan for rack depth and clearance (≥30 cm rear for air cooling) and DC cable cross‑section per rated current; consider external grid protection if feeding back to public mains.
