The UNI-T UDP5250-30 is a single-channel 2000W programmable DC switching power supply delivering 0–250V and 0–30A with auto-ranging across the rated power envelope. It pairs a wide output range with the regulation accuracy, source-emulation and remote control expected of a professional programmable supply.
Voltage accuracy is ±(0.05% of set + 0.05% of rated) and current accuracy ±(0.5% of set + 0.1% of rated); ripple is held to 50mV p-p with a 100 ppm/°C temperature coefficient. A 2.4-inch TFT-LCD shows voltage, current and power together, and full SCPI control over USB and LAN drops the UDP5040-200 straight into LabVIEW, Python-VISA or any ATE framework.
- 2000W / 0–250V / 0–30A — auto-ranging across the rated power envelope
- Voltage accuracy ±(0.05% of set + 0.05% of rated); current accuracy ±(0.5% of set + 0.1% of rated)
- Low ripple — 100mV p-p voltage, 60mA rms current (20 MHz BW)
- CC/CV priority slope modes — choose voltage-first or current-first turn-on for DUT safety
- Adjustable internal resistance to 6.250Ω — emulate batteries, fuel cells and solar sources
- List Mode — 128 programmable V/I/dwell steps, 1 to 9,999, infinite cycles, stand-alone
- Front and rear output terminals (front limited to 10 A)
- Multi-unit series/parallel — up to 2 parallel / 2 series
- USB + LAN with full SCPI 1999.0 / IEEE-488.2; 2.4-inch TFT-LCD
- Discharge-load control for rapid output bleed-down
Applications
- EV-Traction and High-Voltage Conversion: 0–250 V reaches the DC-link voltages of EV-traction inverters, solar string simulators and high-voltage SiC/GaN converter test.
- Solar-Inverter and Grid-Tie R&D: Source emulation and List Mode replicate panel and string behaviour for MPPT and inverter validation without a physical array.
- Automated Test and Production: SCPI over USB or LAN plus stored List Mode sequences make the UDP5000 a clean fit for unattended characterisation, burn-in and end-of-line test.
