UDP3305S 4Ch 328W 30V/5A Programmable Linear DC Power Supply

Programmable, low-noise bench power for electronics development and testing. The UNI-T UDP3305S is a 4-channel, 328W linear DC power supply designed for engineering benches, embedded development, electronics repair and automated test setups.

• Four output channels: CH1 and CH2 provide 0–30V/5A, CH3 provides 0–6V/3A, and CH4 provides a 5V/2A USB output.
• Fine control: 1 mV voltage and 1 mA current setting resolution.
• Series and parallel operation: combine CH1 and CH2 for up to 60V in series or 10A in parallel.
• Linear output: designed for low-ripple applications where clean bench power matters.
• 4.3-inch TFT display: view voltage, current and power information directly on the instrument.
• Programmable operation: supports list output, delay functions and stored configurations.
• Connectivity: LAN, RS-232, USB and digital I/O support integration with automated test environments.
• Protection: over-voltage, over-current and over-temperature protection help protect connected equipment.

Ideal for: electronics prototyping, sensor and embedded-system development, repair benches, laboratory work and automated testing.

Key specifications: 328W total output, 4 channels, 30V/5A primary-channel capability, 1 mV/1 mA setting resolution.
