UTP3305-II 3Ch 335W 32V/5A Linear DC Power Supply
Product Details
UPC: 6935750513408
Manufacturer: UNI-T
Warranty: 3 years

Equipment Type: DC Power Supply
The UTP3305-II is a precision refresh of the three-channel UTP3305 linear platform with 335 W total output. CH1 and CH2 are adjustable from 0–32 V at 0–5 A and CH3 provides a fixed 5 V at 3 A; a four-digit LED reads voltage and current per channel at 10 mV / 1 mA resolution. Linear regulation holds output ripple under 1 mVrms, with load regulation of CV
An automatic CV/CC crossover with current-limit protection handles changing loads, and CH1 and CH2 combine in series for up to 64 V or in parallel for up to 10 A. A temperature-controlled cooling fan scales airflow with internal temperature, and a front-panel master output ON/OFF is provided.
Operation is knob-and-button from the front panel with no remote interface, suiting it to bench analog work, service, and education.
