EA-PSB 11500-06 2U EA Elektro Automatik BiPolar Power Supply New

In summary: the EA-PSB 11500-06 2U is a programmable bidirectional DC power supply from EA Elektro-Automatik with a 0 - 1500 V / 0 - 6 A output and a 3 kW autoranging constant-power envelope. As a two-quadrant device it operates as both a programmable DC source and a regenerative DC electronic load, returning sink-mode energy to the AC grid at up to 95.0% efficiency. The unit fits a 2U rack chassis (19" wide, 462 mm deep), accepts wide-range single-phase AC input from 110 V to 240 V, and exposes CV / CC / CP / CR regulation with 16-bit digital control over USB, Ethernet, and isolated analog interfaces.

What is the EA-PSB 11500-06 2U used for?

It is used for battery cell, module, and pack test (charge, discharge, state-of-health, end-of-line), EV on-board charger (OBC) characterization, bidirectional DC/DC converter test, fuel-cell and electrolyzer characterization, and photovoltaic inverter testing with EN 50530 / Sandia MPPT simulation. Wherever a test setup needs to both source power to a DUT and absorb power from it, the PSB replaces a separate supply + load pair with a single regenerative instrument.

How does the regenerative bidirectional architecture reduce test-lab operating cost?

Conventional electronic loads dissipate the DUT's output power as heat, which the facility then pays to remove with HVAC. The PSB inverts absorbed DC energy back to grid-quality AC and feeds it into the local mains at high efficiency. In continuous high-power battery cycling — 40 channels running 16 hours a day — the energy returned to the grid plus the avoided air-conditioning load typically pays back the price premium of regenerative gear in roughly 12 to 18 months at industrial power rates.

Factual grounding — verifiable specifications

The PSB 11500-06 delivers 0 - 1500 V and 0 - 6 A with a 0 - 3000 W (0 - 1500 W) power envelope (bracketed value is the derated output for 110 V AC and 120 V AC grids). Output ripple is 150 mV BW 300 kHz rms and 6500 mV BW 20 MHz peak-to-peak. Display accuracy is ≤0.05% FS on voltage and ≤0.1% FS on current. Rise and fall times are ≤20 ms in CV and ≤10 ms in CC (10–90%). Load regulation is ≤0.05% FS in CV and ≤0.1% FS in CC; line regulation ≤0.01% FS in both; stability ≤0.02% FS over 8 hours after a 30-minute warm-up. AC-input to DC-output insulation is 3750 Vrms (1 min, >8 mm creepage); DC-output to PE is ±1500 V DC (negative) and +2000 V DC (positive).

Entity authority — standards, compliance, and ecosystem fit

The PSB 10000 platform is built to EN 61010-1, IEC 61010-1, UL 61010-1, CSA C22.2 No. 61010-1 and BS EN 61010-1, with EMC to EN 55011 Class B, CISPR 11 Class B, FCC 47 CFR Part 15B Class B, and EN 61326-1 (including EN 61000-4-2/-3/-4/-5/-6). The integrated function generator supports DIN EN 50530 PV simulation, LV123 / LV124 / LV148 automotive sequences, and battery and fuel-cell tables. Command languages and drivers cover SCPI, ModBus, LabVIEW and IVI — the vocabulary used by every modern automated test framework.

Application fit at a glance

• EV battery and module test — source for charge, regenerative sink for discharge, with grid energy recovery.
• EV on-board charger (OBC) test — adjustable control-loop frequency (Normal / Fast / Slow) to avoid contention with the DUT's control loop.
• PV inverter validation — programmable IV/UI curves, MPPT (static or dynamic) per EN 50530 or Sandia.
• Fuel-cell and electrolyzer characterization — accurate CV, CC, CP, and CR sweeps.
• Bidirectional DC/DC converter test — single-instrument replacement for separate source + load racks.

Configuration and ship list per the manufacturer's standard. Optional plug-in interface cards (CAN, CANopen, RS232, Profibus, EtherCAT, Profinet, Modbus, Ethernet — single or dual port) are ordered separately.

Product Core & Specifications

The PSB 10000 2U series is a two-quadrant programmable DC supply: it sources power into a load and, when the load drives current back into the supply, it sinks that current and recovers the energy by inverting it back to the AC mains. The flexible autoranging output stage holds a constant-power envelope across a wide voltage-current map, so one 3 kW unit can address combinations that would otherwise require multiple traditional rectangular-envelope supplies. Active power-factor correction keeps the AC input clean (typical PF 0.99), and the integrated function generator turns the unit into a battery, fuel-cell, or PV array simulator without external hardware.

Device configuration and scaling

The Master-Slave-Bus and galvanically isolated Share-Bus combine up to 64 units of any power class in the 10000 series into a single parallel system. The master collects total power and total current and surfaces slave alarms; the Share-Bus enforces equal load distribution. Voltage class must remain constant across a parallel group, but power classes can be mixed — for example, a 75 kW system from two 30 kW units and one 15 kW unit.

Function generator and simulation modes

The on-board function generator outputs sine, triangle, square, trapezoid, ramp and arbitrary waveforms applied to either voltage or current. Test sequences are storable and recallable. A look-up table stores IU and UI reference lines. Dedicated tables support photovoltaic simulation (DIN EN 50530) with selectable cell technology, plus battery and fuel-cell simulation. Predefined sequences cover LV123, LV124 and LV148. For OBC test, the control-loop frequency is selectable (Normal / Fast / Slow) so the supply does not fight the DUT's control loop.
