30-Second Fit Check

Output: 0-1500V, 0-20A, 10000W with true autoranging (U/I/P).

AC input: 380-480V ±10%, 3-phase, 45-66Hz. On 208V input, derates to 6000W.

Efficiency: ≤95.5% at full load and full output voltage.

Regulation: Load regulation CV ≤0.05% FS, line regulation ≤0.01% FS.

Ripple: ≤400mV rms / ≤2400mV pp (CV mode, 300 kHz / 20 MHz BW).

Protections: Adjustable OVP, OCP, OPP, plus OT, PF.

Built-in internal resistance simulation (2.6Ω – 4500Ω).

What It Is + Why It Matters

Ultra-high-voltage single-channel programmable DC power supply for EV battery packs (up to 1500V), fuel cell stacks, solar string inverters, and high-power industrial R&D.

Autoranging output delivers full 10000W across wide voltage/current range – no manual range switching.

Built-in internal resistance simulation for battery and load emulation.

Master-Slave parallel operation – up to 64 units for 960kW total power; true current sharing via Share bus and digital MS bus.

High stability: temp coefficient CV ≤30ppm/°C after warm-up.

Note: Remote sensing compensates up to 5% of U_Nom. Always use DC terminal covers – hazardous voltage possible (1500V).

Best for / Not for

Best for: Ultra-high-voltage battery pack testing (EV, ESS up to 1500V), fuel cell stack evaluation, solar string inverter MPPT characterization, on-board charger (OBC) test for heavy-duty EVs, DC-DC converter validation for high voltage, and capacitor bank charging.

Not for: Applications requiring output above 1500V or above 20A per unit (use master-slave parallel); low-voltage high-current applications (consider other PS 10000 models).

Selection Checklist + Integration

Confirm AC supply: 3-phase 380-480V recommended for full 10000W; on 208V derated to 6000W.

DC cable cross-section: For 20A / 5m length, use at least 2.5mm² (AWG13) with insulation rated for 1500V DC (use high-voltage cables).

Mounting: 19" rack, 3U height, allow >30cm rear clearance for airflow.

For master-slave parallel: Connect Share bus (BNC) and MS bus (RJ45 CAT5); configure termination (BIAS/TERM) per manual.

For remote sense: Use included sense plugs to compensate voltage drop at load terminals, especially at high voltage.

For internal resistance mode: Activate R mode in the quick menu to simulate battery internal resistance.

Firmware: KE/HMI 3.02+ recommended for SEMI F47 support.
