In summary, the **EA-PSB 10080-510 3U US208V** is a programmable, bidirectional, two-quadrant DC power supply from EA Elektro-Automatik in the PSB 10000 3U series, rated at 0 – 80 V, 0 – 510 A, and 0 – 15,000 W in a 3U 19-inch rack-mount enclosure. It operates simultaneously as a precision constant-voltage / constant-current / constant-power / constant-resistance source (with fast crossover between modes) and as a regenerative electronic load that returns absorbed energy to the AC mains at efficiencies up to 94.5%. The unit ships in the US208V variant — engineered for North American 208 V three-phase service, with EA factory product code 30238701.

## What is the EA-PSB 10080-510 3U US208V used for?

The EA-PSB 10080-510 3U US208V is used for high-power battery cycling, EV powertrain and on-board charger characterization, fuel-cell and electrolyzer test, photovoltaic-inverter simulation, and any application that requires a DC source and a regenerative DC sink in the same enclosure. Its primary commercial advantage is energy recovery: in load operation it returns up to 94.5% of absorbed energy to the AC grid, eliminating the resistive-bank heat load and the HVAC overhead that accompanies conventional electronic loads in continuous-cycle test bays.

## What does autoranging mean on the PSB 10000 series?

Autoranging means the 15,000 W output stage delivers full rated power across a wide combination of voltage and current values, not just at one fixed V/I corner. Within the 80 V envelope the unit can supply higher current at lower voltages and reduced current at higher voltages, all while holding the 15,000 W constant-power characteristic. The practical effect is that a single EA-PSB 10080-510 3U US208V can replace several traditional supplies that each cover narrow V/I rectangles, simplifying test-bay configuration and reducing capital outlay.

Hard performance grounding: CV load regulation ≤0.05% FS, CC load regulation ≤0.1% FS, CV stability ≤0.02% FS across 8 hours after warm-up, CV/CC line regulation ≤0.01% FS across the 208 – 480 V ±10% input range. CV ripple is ≤10 mV rms (300 kHz BWL) and ≤100 mV peak-to-peak (20 MHz BWL). Voltage display accuracy is ≤0.05% FS and current display accuracy is ≤0.1% FS, both supported by 16-bit ADCs and DACs. CV rise/fall (10–90%) ≤10 ms in source mode and CC rise/fall ≤2 ms in sink mode. Output capacitance is 23,970 μF and resistance range is 0.006 Ω – 9 Ω.

The PSB 10000 series is engineered to EN 61010-1, IEC 61010-1, UL 61010-1, CSA C22.2 No 61010-1, and BS EN 61010-1 safety standards, with EMC tested to EN 55011 (Class B for Standard models, Class A for US208V models), CISPR 11, FCC 47 CFR Part 15B, and the EN 61326-1 immunity test suite (EN 61000-4-2 through 61000-4-6). Built-in test profiles cover the EN 50530 photovoltaic inverter standard, Sandia PV models, and the LV123 / LV124 / LV148 automotive power-quality procedures, aligning the unit directly with the compliance frameworks used by global automotive, energy-storage, and grid-interface OEMs.

### Where the EA-PSB 10080-510 3U US208V fits in a test plan

-   **EV battery cell, module, and pack cycling** — charge with CV/CC, discharge with regenerative CC/CP, log SOH and EOL data via EA Power Control.
-   **On-board charger (OBC) qualification** — Normal / Fast / Slow voltage-regulation speed modes prevent control-loop competition with the DUT.
-   **Battery and fuel-cell simulation** — adjustable I/V table emulates real cells with OCP, voltage-window monitoring, and alarm output.
-   **Photovoltaic inverter test** — EN 50530 and Sandia MPPT curves built in; daily-trend simulation supported.
-   **DC/DC converter and traction inverter test** — bidirectional operation removes the need for a separate load when both source and sink are required.
-   **Scalable systems** — Master-Slave and Share-Bus interconnect up to 64 PSB 10000 units of mixed power class (same voltage class), enabling systems up to 960 kW from a single voltage rating.

## Product Core & Full Specifications

The bidirectional architecture of the PSB 10000 series replaces two instruments — a programmable DC supply and a DC electronic load — with one chassis. In source mode the unit behaves as a precision four-mode regulator (CV / CC / CP / CR) with fast mode crossover. In sink mode it behaves as a regenerative electronic load: instead of converting the DUT’s output power to heat in a resistor bank, the PSB inverts it back to the AC mains. For continuous-cycle test environments the operating-cost difference between resistive dissipation and grid feedback is the dominant financial argument for the series.

The EA-PSB 10080-510 3U US208V variant is the US208V variant — engineered for North American 208 V three-phase service. AC input voltage and per-phase current behavior depend on the variant; the table below reflects this exact configuration.

**Note on optional interface cards:** The CAN, CANopen, RS232, Profibus, EtherCAT, Profinet, Modbus, and additional Ethernet plug-in cards are optional add-ons. If your test plan requires a specific industrial interface, confirm the option with your Test Architect at order time so the correct card is fitted.

**Note on paralleling:** The Master-Slave bus and Share-Bus carry low-level control signals — units in a parallel system must share the same voltage class. Mixed power classes (5 / 10 / 15 kW) are permitted on the same voltage rail; mixed voltage ratings are not.
