The UNI-T UDP5800-2 is a single-channel 400W programmable DC switching power supply delivering 0.5–800 V and 0–2A 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.
- 400W / 0.5–800 V / 0–2A — 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 — 200mV p-p voltage, 6mA 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 300Ω — 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 — 4 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
- EV Traction Battery R&D: 400 W at 800 V supports early-stage validation of individual 400 V and 800 V EV pack modules, pre-compliance testing, and characterisation at low formation current.
- High-Voltage PV Research: Emulates utility-scale string voltages up to 840 V for MPPT algorithm development, inverter front-end validation, and rapid-shutdown testing.
- Capacitor Formation and Aging: High-voltage electrolytic and film capacitor formation requires stable DC up to the rated voltage — the 800 V range covers most high-voltage film cap grades.
