The UNI-T UDP5800-10 is a single-channel 2000W programmable DC switching power supply delivering 0.5–800 V and 0–10A with auto-ranging across the rated power envelope. It brings the same platform-level accuracy, source-emulation capability, and SCPI remote control as the rest of the UDP5000 family to high-voltage applications — 400 V and 800 V EV traction batteries, high-string PV, industrial DC bus — that lower-voltage tiers cannot reach.
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 / 0.5–800 V / 0–10A — 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 — 250mV p-p voltage, 30mA 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 60Ω — emulate high-voltage source impedance
- List Mode — 128 programmable V/I/dwell steps, 1 to 9,999 or infinite cycles, stand-alone
- Front and rear output terminals (front limited to 10 A)
- Multi-unit parallel only — 2 units maximum; series connection not supported at 800 V
- USB + LAN with full SCPI 1999.0 / IEEE-488.2; 2.4-inch TFT-LCD
- Discharge-load control for rapid output bleed-down; enhanced isolation — 1900 VAC withstand
Applications
- Full-Pack EV Battery Validation: 2000 W at 800 V is purpose-built for full 400 V and 800 V EV traction pack validation — formation, ageing cycles, and ATE integration with SCPI control.
- Utility-Scale PV String Emulation: High-irradiance string simulation up to 840 V OCV for large-format inverter test, arc-fault detection validation, and system-level PV commissioning.
- Industrial High-Voltage DC Production Test: 10 A at up to 800 V covers end-of-line test for high-voltage drives, industrial converters, and DC-DC modules at production throughput with List Mode automation.
