The UNI-T UDP5080-20 is a single-channel 400W programmable DC switching power supply delivering 0–80V and 0–20A 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.
- 400W / 0–80V / 0–20A — 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, 40mA 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 4.000Ω — 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 4 parallel / 4 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
- Power-Electronics and Motor-Drive Development: 0–80 V spans 48 V / 60 V / 72 V battery and DC-bus rails common in motor-drive and industrial converter design. Adjustable slew rate controls how fast the bus is energised into capacitive DC links.
- R&D Bench and Production: List Mode and SCPI scripting make repeatable bring-up and end-of-line routines straightforward without an attended operator.
- 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.
