Unit UTP3305-II is a linear DC power supply with 3 outputs from the UNI-T UTP3300-II series. It offers two adjustable channels of 0–30 V / 0–5 A and a fixed 5 V / 3 A output; total output power is 315 W. CH1 and CH2 can be operated independently, or in series or parallel tracking mode. On the 4-digit LED display, voltage and current are shown with 10 mV / 1 mA resolution; precise adjustment is made with multi-turn potentiometers. It has overvoltage, overtemperature and reverse polarity protections and a temperature-controlled fan.
