UNI-T UDP3303A Power Supply

UNI-T UDP3303APower Supply

The UNI-T UDP3303A is a compact 3-channel DC bench power supply designed for lab, repair and development work. It combines two fully adjustable channels for general-purpose bench use with a third low-voltage selectable channel for logic/ICS testing. The front panel arranges coarse/fine control knobs, numeric displays and indicators for fast setup and readout, making repetitive bench tasks quick and predictable.

Internally the UDP3303A delivers stable, low-noise outputs with fine resolution for precision adjustment and built-in protections (OVP/OCP/short-circuit/OTP) to protect both DUT and supply. Its total output capability supports moderate power requirements while remaining small enough for crowded workbenches. The product family manual and retail datasheets document measurement accuracy, resolution and protection behavior.

Features:

• Three independent output channels (two adjustable, one selectable low-voltage).
• Two adjustable channels: up to 30 V / 3 A per channel.
• Third channel: selectable low-voltage output (1.8V / 2.5V / 3.3V / 5V) for logic supply needs.
• Total output power ~195 W (aggregate limit across channels).
• Fine voltage/current resolution (voltage 10 mV, current 1 mA).
• Built-in protections: OVP, OCP, short-circuit protection and thermal protection.
• Memory groups for recall of common settings (M1M5 on supported firmwares).
