The UNI-T UDP5040-200 is a single-channel 2000W programmable DC switching power supply delivering 0–40V and 0–200A 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 / 0–40V / 0–200A — 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 — 50mV p-p voltage, 400mA 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 0.20Ω — 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
- Battery and Energy-Storage Test: The wide 0–40 V range covers 12 V to 36 V lithium-ion and LFP packs used in e-bike, power-tool and light-EV work. Internal-resistance emulation and List Mode let you reproduce charge profiles and varying pack states without cycling real cells.
- New-Energy and Automotive Electronics: DC/DC converter input stages, inverter front ends and sub-40 V automotive ECUs benefit from the tight regulation, low ripple and CC/CV priority control.
- 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.
