30-Second Fit Check

Need a single unit that can source and sink high power? Models span 10V to 2000V, with currents up to 1000A.
DC power: 10kW or 30kW with fully autoranging output; regenerative energy recovery up to 96.5%.
Seamless two-quadrant operation between source and sink modes with automatic crossover.
Built‑in 5" TFT touch panel with function generator, battery test, and MPPT tracking.
Protection suite: OVP, OCP, OPP, OT, PF, MSP, SF; master-slave parallel for up to 64 units (1920kW).

What It Is + Why It Matters

Compact 4U 19" rack bidirectional DC power supply integrating both a programmable source and a regenerative electronic load in one device.
The autoranging output stage delivers maximum voltage at lower current or maximum current at lower voltage; sink mode recovers up to 96.5% of absorbed energy back to the grid.
Advanced simulation capabilities: simple and extended PV (EN 50530), fuel cell, battery test, and MPPT tracking enable comprehensive component testing without extra hardware.
Multiple galvanically isolated interfaces: analog (0-5/10V), USB, Ethernet plus optional industrial buses (CAN, Profibus, ProfiNet, EtherCAT, ModBus TCP, RS232).
True master-slave parallel operation for up to 64 units with Share bus for dynamic current balancing; optional water cooling for reduced noise and better thermal management.

Note: In sink mode, the device recovers energy to the grid; consult local utility regulations and consider a grid protection device. 30kW models derate to 18kW at 208V AC input. Must be installed in a closed 19" rack with adequate ventilation or optional water cooling.

Key Specs

AC input: 208-480V AC, 3-phase, active PFC, 45-65Hz; 30kW models derate to 18kW at 208V.

Integration & Installation

DC output via copper busbars (M10 or M6 bolts) on the rear panel; plastic covers and strain relief accessories included.
AC mains via 5-pole connector (3x L, N, PE) or 4-wire (3x L, PE); fixed connection required with external circuit breaker.
Master-slave connection via standard CAT5 patch cables; Share bus via BNC coaxial cables (50Ω).
Optional water cooling available; must be installed in a closed 19" rack/cabinet with lockable doors and adequate ventilation or water supply.

Best for / Not for

Best for: Battery charge/discharge cycling, solar inverter testing with PV simulation (EN 50530), fuel cell simulation, automotive 48V/400V/800V system validation, bidirectional DC-DC converter testing, and any application requiring a seamless source-sink transition with high-power energy recovery.
Not for: Applications requiring only a dedicated electronic load without source capability, environments without adequate rack cooling, direct series connection in sink mode (not permitted), or locations without proper three-phase AC supply and grid compliance for energy feedback.

Selection Checklist + RFQ

Choose voltage/current model matching your test requirements (10V, 60V, 80V, 200V, 360V, 500V, 750V, 920V, 1000V, 1500V, or 2000V).
Verify total power demand ≤ 10kW or 30kW, noting autoranging characteristics and derating to 18kW at 208V AC input for 30kW models.
Confirm three-phase AC supply availability (208-480V AC) and plan for fixed connection with proper circuit protection.
Select required interfaces: built-in analog/USB/Ethernet plus any optional industrial bus modules (e.g., CAN, ProfiNet).
For master-slave operation, specify total system power and number of units; ensure all units have the same voltage rating.
Plan for energy recovery grid compliance and possible grid protection device installation; consider optional water cooling for high-density cabinets.
