Description

30-Second Fit Check

Need a single unit that sources and sinks DC power? Output is 0–80 V, current ±60 A (source +60 A, sink -60 A).
Rated power: 1500 W (1200 W at 110–127 VAC) with autoranging (U/I/P).
In sink mode, up to 94% of consumed energy is recovered and fed back into the local grid.
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 (plus Safety OVP on 60 V models only).
Resistance range: 0.04–80 Ω; ripple typical 10 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

True bidirectional DC power supply – functions seamlessly as a laboratory power supply (source) and electronic load (sink) in one 2U chassis, eliminating the need for separate instruments.
Autoranging output stage delivers up to 60 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 94% of consumed DC energy back into the local grid, dramatically reducing cooling costs and enabling greener test labs.
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.

Integration & Installation

Standard 19″ rack‑mount, 2U height; DC terminal on rear panel (copper blades with protective covers).

Rear panel: DC terminal, remote sense, Share bus (BNC ×2), master-slave bus (RJ45 ×2), analog interface (D‑Sub), USB‑B, Ethernet, interface module slot, grounding point (PE).
Cooling: temperature‑controlled fans; ensure ≥30 cm clearance behind the unit and adequate rack airflow.
Grid connection for sink mode: consult local regulations regarding energy feedback; external NS protection device may be required (VDE‑AR‑N 4105/4110, G99, etc.).

Best for / Not for

Best for: battery charge/discharge cycling, fuel cell and solar panel simulation (including EN 50530), DC motor drive testing with regeneration, bidirectional DC‑DC converter validation, and automated ATE where a single instrument must source and sink power with energy recovery.
Not for: applications needing output voltage above 80 V, current beyond ±60 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 ≤ 80 V, current ≤ ±60 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 high‑current wiring, use ≥16 mm² (AWG6) DC cables with ring lugs for the copper blade terminals.
If master-slave operation is planned, ensure all units have matching voltage ratings and prepare BNC and CAT5 cables.
For battery test, PV, or fuel cell simulation, verify that built‑in function parameters match your test profiles.
Plan rack depth (≥559 mm total) and cooling; the bidirectional energy‑recovery design minimises HVAC requirements in high‑duty‑cycle testing.
