UNI-T UDP3303A Programmable DC Power Supply 3-Channel 195W

The UNI-T UDP3303A is a high-precision programmable DC power supply featuring three independent output channels (two adjustable 0-30V/0-3A and one fixed 2.5V/3.3V/5V/3A). With a total power of 195W, it is ideal for laboratory, educational, and industrial applications requiring stable and accurate voltage/current sourcing.

Advantages

Equipped with a 4.3-inch TFT LCD display for clear readouts, the UDP3303A offers excellent load regulation (≤0.01%+3mV for voltage, ≤0.1%+3mA for current) and low ripple/noise (≤1mVrms voltage, ≤3mArms current). It includes comprehensive protection features (OVP, OCP, OTP) and supports remote sensing, list mode, timer functions, and output ON/OFF control. The unit can be programmed via USB or LAN (GPIB optional).
