Description

30-Second Fit Check

Output: 0-1000V, 0-10A, 3000W with true autoranging (U/I/P).
AC input: 110-127V / 208-240V ±10% (single phase or two-phase), 45-65Hz. On 110V input, output derates to 1500W.
Efficiency: ≤95% at full load and full output voltage.
Regulation: Load regulation CV ≤0.05% FS, line regulation ≤0.01% FS.
Ripple: 100mV rms / 2000mV pp (CV mode, 300 kHz / 20 MHz BW).
Protections: Adjustable OVP, OCP, OPP, plus OT, PF.
Cooling: Variable speed fan (standard) or optional water cooled for silent operation in clean environments.

What It Is + Why It Matters

High-voltage programmable DC power supply for R&D labs, EV battery testing, PV inverter validation, and industrial ATE.
Autoranging output delivers full 3000W across wide voltage/current range – no manual range switching.
Built-in function generator with sine, triangle, rectangle, trapezoid, arbitrary (99 points), ramp, DIN 40839, plus PV and fuel cell simulation (EN 50530 compliant).
Master-Slave parallel operation – up to 64 units for 192kW total power; genuine 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 when hazardous voltages present.

Best for / Not for

Best for: High-voltage battery pack testing (EV, ESS), solar inverter MPPT testing (PV simulation up to 1000V), fuel cell simulation, DC-DC converter validation, capacitor charging, and automotive electronics (DIN 40839).
Not for: Applications requiring output above 1000V or above 10A per single unit (use master-slave parallel to scale current); low-voltage high-current applications (consider other PSI 10000 models).

Selection Checklist + Integration

Confirm AC supply: 208-240V recommended for full 3000W; on 110-127V derated to 1500W.
DC cable cross-section: For 10A / 5m length, use at least 2.5mm² (AWG13) with appropriate insulation rating for 1000V.
Mounting: 19" rack, 2U height, allow >30cm rear clearance for airflow. For silent operation, consider optional water cooling.
For master-slave parallel: Connect Share bus (BNC) and MS bus (RJ45 CAT5); configure termination (BIAS/TERM) per manual.
For high-voltage safety: Always use included DC terminal covers and follow discharge procedure (capacitors may hold charge).
For PV simulation: Prepare IU table (4096 points) on USB or use internal EN50530 day trend; connect a solar inverter as load.
Firmware: KE/HMI 3.02+ recommended for extended PV functions and SEMI F47 support.
