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 10500-10 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 10500-10 delivers 0 - 500 V and 0 - 10 A with a 0 - 1500 W (0 - 1200 W) power envelope (bracketed value is the derated output for 110 V AC and 120 V AC grids). Output ripple is 40 mV BW 300 kHz rms and 500 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. ## Accessories Supplied Item Description EA-PSB 10500-10 2U unit Programmable bidirectional DC power supply, article 30000724 AC input connector / mains plug Region-appropriate cordset or terminal assembly for the rear AC input DC bus-bar contact protection cover Snap-on cover for the rear DC output copper rails Documentation Manufacturer manual, safety notices, and standard quick-start material _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 1.5 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. ### PSB 10500-10 — DC output Voltage range 0 - 500 V Current range 0 - 10 A Power range 0 - 1500 W (0 - 1200 W) Resistance range 2 Ω - 3000 Ω Ripple rms (CV) 40 mV BW 300 kHz Ripple and noise p-p (CV) 500 mV BW 20 MHz UMin for IMax (Sink) 2.5 V Output capacity 120 μF Efficiency up to 95.0% (at 100% Power and 100% Output voltage) Article number 30000724 _The bracketed power figure in Power range is the derated output applicable when fed from a 110 V AC or 120 V AC grid._ ### AC input, regulation, dynamics, accuracy AC input 110 / 120 / 208 / 220 / 230 / 240 V ±10%, 1ph; 45–66 Hz; PF >0.99; leakage <3.5 mA; OV cat. 2; pollution deg. 2 Load regulation CV / CC / CP / CR ≤0.05% FS / ≤0.1% FS / ≤0.3% FS / ≤0.3% FS + 0.1% FS current Line regulation CV / CC ≤0.01% FS / ≤0.01% FS (110–240 V AC ±10%) Stability CV / CC ≤0.02% FS / ≤0.02% FS over 8 h after 30 min warm-up Temp coefficient CV / CC ≤30 ppm/°C / ≤50 ppm/°C following 30 min warm-up Compensation (remote sense) ≤5% UNominal Rise / fall time CV (10–90%) ≤20 ms / ≤20 ms Rise / fall time CC (10–90%) ≤10 ms / ≤10 ms Display accuracy Voltage ≤0.05% FS, Current ≤0.1% FS ### Protection - **OVP** — adjustable 0–110% UNominal. - **OCP** — adjustable 0–110% INominal. - **OPP** — adjustable 0–110% PNominal. - **OT** — output shuts down on insufficient cooling. ### Insulation AC-Input to DC-Output 3750 Vrms (1 min), creepage >8 mm AC-Input to case (PE) 2500 Vrms DC-Output to Interfaces 1000 V DC (≤360 V models), 1500 V DC (≥500 V models) Negative DC pole <-> PE ±1500 V DC Positive DC pole <-> PE +2000 V DC ### Interfaces - **Built-in (galvanically isolated):** USB, Ethernet (100 Mbit), 15-pole D-Sub isolated analog (0–10 V or 0–5 V switchable), USB Host, Master-Slave-Bus, Share-Bus. - **Analog signals:** Inputs U / I / P / R, remote control on/off, DC output on/off, resistance mode on/off.

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. ### Safety, EMC, environment, mechanical Safety EN 61010-1, IEC 61010-1, UL 61010-1, CSA C22.2 No. 61010-1, BS EN 61010-1; protection class 1; IP20 EMC EN 55011 Class B; CISPR 11 Class B; FCC 47 CFR Part 15B Class B; EN 61326-1 incl.
