Description

30-Second Fit Check

Need a single unit that sources and sinks medium‑voltage DC power? Output is 0–500 V, current ±10 A (source +10 A, sink -10 A).
Rated power: 1500 W (1200 W at 110–127 VAC) with autoranging (U/I/P).
In sink mode, up to 95% of consumed energy is recovered and fed back into the local grid.
Built‑in discharge circuit reduces output to <60 V within ≤10 s after DC off – essential for 500 V safety.
AC supply: 110–240 VAC, 45–65 Hz, single‑phase (derates to 1200 W at 110–127 VAC).
Protection: OVP, OCP, OPP, OT, PF, MSP, SF (separately configurable for source and sink).
Resistance range: 2–3000 Ω; ripple typical 40 mVrms (BW 300 kHz).
Weight approx. 9.5 kg; dimensions 19″ × 2U × 462 mm enclosure, total depth min. 559 mm.

What It Is + Why It Matters

Medium‑voltage bidirectional DC power supply – functions seamlessly as a laboratory power supply (source) and electronic load (sink) in one 2U chassis, eliminating separate instruments for 500 V testing.
Autoranging output stage delivers up to 10 A in either direction; voltage, current, and power limits are independently adjustable for source and sink modes.
In sink mode, the built‑in energy recovery feeds up to 95% of consumed DC energy back into the local grid, dramatically reducing cooling costs for high‑voltage test environments.
Built‑in discharge circuit rapidly reduces output voltage after shutdown – critical for operator safety at 500 V working levels.
Integrated function generator (sine, triangle, rectangle, trapezoid, DIN 40839, ramp, arbitrary up to 99 points, XY table) plus dedicated PV, fuel cell, and battery simulation functions replace costly external test equipment.
Master-slave parallel operation supports up to 64 units (96 kW total) with true totaling of actual values; mixed power classes and PSBE series slaves are supported.
Optional industrial interface modules (Profibus, ProfiNet, CAN, CANopen, RS232, ModBus TCP, EtherCAT) plug into the rear slot for direct PLC integration.

Note: The device automatically derates to 1200 W when running on 110–127 VAC supplies. For sink mode energy recovery, a suitable grid connection and possibly an external NS protection device (per local regulations) are required. The discharge circuit provides essential safety at 500 V – always verify voltage decay before handling connections.

Best for / Not for

Best for: medium‑voltage battery charge/discharge cycling, photovoltaic inverter testing up to 500 V, fuel cell simulation, DC‑DC converter validation, and automated ATE where a single instrument must source and sink power with energy recovery and built‑in safety discharge at 500 V.
Not for: applications needing output voltage above 500 V, current beyond ±10 A, or sustained power above 1500 W (1200 W at low line). Not suitable for off‑grid or generator supplies in sink mode.

Selection Checklist + RFQ

Confirm required DC voltage ≤ 500 V, current ≤ ±10 A, sustained power ≤ 1500 W (1200 W at 110–127 VAC).
Verify AC mains: 110–240 VAC single‑phase; for sink mode, check local grid‑feedback regulations.
Choose remote control method: built‑in analog/USB/Ethernet, or add an optional industrial bus module (Profibus, CAN, etc.).
For 500 V wiring, ensure DC cables have adequate voltage rating; use appropriate ring lugs and terminal covers.
If master-slave operation is planned, ensure all units have matching 500 V ratings and prepare BNC and CAT5 cables.
For 500 V safety, always verify the discharge circuit is operational and wait ≥10 s before handling DC connections.
Plan rack depth (≥559 mm total) and cooling; the 95% energy‑recovery efficiency minimises HVAC requirements in high‑duty‑cycle testing.
