UNI-T UTP3305-II Linear DC Power Supply

The UNI-T UTP3305-II is a three-channel linear DC power supply, featuring adjustable dual-channel and a fixed single-channel output. This model is part of the UTP3000-II series and offers high precision and reliable performance with the following key features:

• High Precision Display: The unit provides a high-precision four-digit voltage and current display, with a resolution of 10mV for voltage and 1mA for current.
• Low Ripple and Noise: It ensures minimal ripple and noise, offering a constant voltage (CV) ripple of ≤1mVrms and a constant current (CC) ripple of ≤3mArms.
• Protection Features: The power supply is equipped with over-voltage protection (OVP), over-current protection (OCP), over-temperature protection (OTP), and reverse polarity protection for added safety.
• Tracking Function: The output channels CH1 and CH2 can operate in a master-slave tracking configuration when connected in series.
• Adjustable Outputs: The output voltage for channels CH1 and CH2 is adjustable from 0V to 32V with a current range of 0A to 5A. Channel CH3 provides a fixed output of 5V with a current range of 0A to 3A.
• Output Control: The unit includes on/off output control, allowing users to easily manage the power supply.
• Temperature-Controlled Cooling: An intelligent temperature control fan helps maintain optimal operating conditions.
• Reliability: The device has a Mean Time Between Failures (MTBF) of ≥2000 hours, ensuring long-term durability.
• Voltage and Current Regulation: It offers excellent load regulation, with CV regulation of <0.01%+3mV and CC regulation of ≤0.2%+3mA.
• Parallel/Series Output Function: The UTP3305-II can output in both parallel and series configurations to meet diverse application needs.
• Input Voltage and Power: The unit operates with an input voltage of 115V AC or 230V AC and a frequency range of 47Hz~63Hz, providing an output power of 335W.

The power supply is compact with dimensions of 319mm (W) x 146mm (H) x 226mm (D) and weighs approximately 10.5kg. It features a 1-year warranty and has a sleek white and grey design with a 4-window LED display.
