EA-PSBE 10060-340 3U Programmable Bidirectional DC Power Supply

The EA-PSBE 10060-340 3U is a 10 kW bidirectional DC power supply from the PSBE 10000 series, designed for two‑quadrant operation as both a power supply and a regenerative load. It delivers a voltage from 0 to 60 V and a current from 0 to 340 A, with autoranging output that maintains full power across a wide operating range. With an efficiency of up to 94.5% (at full power and nominal voltage), the unit recovers energy normally dissipated as heat and feeds it back into the grid, reducing energy costs and cooling requirements. The device features a 5" colour TFT touch display, digital control with 16‑bit ADCs/DACs, and high regulation accuracy (CV ≤0.05% FS, CC ≤0.1% FS). Built‑in interfaces include USB, Ethernet, a galvanically isolated analog interface (0‑5 V/0‑10 V switchable), USB host, Master‑Slave‑Bus, and Share‑Bus. It accepts a wide three‑phase AC input of 208‑480 V ±10% with active PFC (typical 0.99). Up to 64 units of the same voltage class can be paralleled via the Master‑Slave‑Bus to form systems up to 640 kW and 64,000 A. Typical applications include battery testing, battery simulation, fuel cell testing, on‑board charger testing, and battery recycling discharge.

Key Features

• Bidirectional Operation (Two‑Quadrant): Seamlessly switches between sourcing and sinking current; in load mode energy is regenerated to the grid with efficiency up to 94.5% for this model.
• Autoranging Output: Provides 0‑60 V, 0‑340 A, and 10 kW full power across a wide voltage‑current range, eliminating the need for multiple supplies.
• High Precision & Dynamics: 16‑bit resolution for voltage, current, power, and resistance control; fast crossover between CV, CC, CP, and CR modes; low ripple (≤10 mV rms, ≤100 mV p‑p).
• Wide AC Input & Grid Support: Three‑phase input 208‑480 V ±10% with active PFC (＞0.99) and regenerative operation with low harmonic distortion.
• Comprehensive Connectivity: Built‑in USB, Ethernet, analog interface (15‑pole D‑Sub), and USB host for data logging; optional fieldbus modules (CAN, CANopen, RS232, Profibus, EtherCAT, Profinet, Modbus).
• Scalable Parallel Systems: Master‑Slave‑Bus and Share‑Bus allow up to 64 units to operate as a single unit with equal load sharing, achieving system currents up to 64,000 A.
• Intuitive Operation: 5" TFT touch display, two rotary knobs with push‑buttons, and clear status indication; sequence and logging functions via EA Power Control or EA Battery Simulator software.
