Description

30-Second Fit Check

Output: 3 independent bidirectional channels, each 0-360V, 0-40A with autoranging (U/I/P).
Total power: 15000W (5000W per channel).
AC input: 208V / 380-480V ±10%, 3-phase, 45-66Hz. No derating on 208V version.
Energy recovery efficiency: up to 95.5% in sink mode.
Ripple: ≤55mV rms / ≤320mV pp (CV mode).
Protections: Adjustable OVP, OCP, OPP, plus OT.
Built-in function generator, battery test, MPPT tracking, and internal resistance simulation.
Cooling: Forced air flow front to rear, temperature-controlled fans.

What It Is + Why It Matters

True 3-channel bidirectional operation – each channel independently sources or sinks power; regenerative energy recovery up to 95.5% reduces heat and electricity costs.
Space-saving design – replaces three single-output units, reducing rack space by >50%.
Parallel testing capability – test inverters, motors, and on-board chargers simultaneously in one setup, accelerating development cycles.
Built-in function generator with sine, triangle, rectangular, arbitrary (99 points), ramp, DIN 40839, plus PV/fuel cell simulation and MPPT tracking.
Master-Slave parallel – up to 8 units for 120kW total system power.
High dynamics: Rise/fall time (CV) ≤10ms, (CC) ≤2ms.

Note: Channels are fully isolated; remote sensing compensates up to 5% of U_Nom. Always use DC terminal covers – hazardous voltage possible (360V).

Best for / Not for

Best for: Multi-channel mid-voltage battery pack/module testing (EV, ESS), electric motor and inverter validation, on-board charger (OBC) testing, DC-DC converter evaluation, fuel cell simulation, solar inverter MPPT tracking, and automotive R&D requiring three independent bidirectional channels up to 360V/40A.
Not for: Applications needing more than 360V or 40A per channel (use master-slave parallel or higher power models); single-channel only applications (overkill).

Selection Checklist + Integration

Confirm AC supply: 3-phase 380-480V or 208V (no derating for 208V version).
DC connection per channel: Copper blades on rear; for 40A, use at least 16mm² (AWG6) per pole with ring lugs (M6 bolt).
Mounting: 19" rack, 3U height, allow >30cm rear clearance for airflow.
For master-slave parallel (up to 8 units): Connect Share bus (BNC) per channel and digital master-slave bus (RJ45).
For energy recovery: Ensure grid connection can accept regenerated power; may require external grid protection per local regulations.
For battery test: Use built-in battery test profiles (static/dynamic discharge) per channel independently.
For communication: Utilize EtherCAT for high-speed synchronized control (1 ms cycle).
Software: EA Power Control (free) and EA Battery Simulator (optional license) included on USB stick.
