UNI-T UDP3300C are cost effective, programmable DC power supplies featuring three independent outputs with excellent performance and a clear interface. The UPD3300C provide constant current (CC) and constant voltage (CV) modes, short circuit and over-voltage protection and much more.

UNI-T offers several models in its UDP3000 power supply series, enabling users to select a feature set best suited for their application. Units differ with front display styles, power ratings, connection options and more. The chart below outlines several main features of each.

The UPD3300C features three independent outputs. Channels 1 and 2 provide 4 digit voltage and current high precision displays with a resolution of 10mV/1mA.

CH3 has 4 sets of fixed outputs which are 1.8V/2.5V/3.3V/5.0V/3A and appear at the bottom of the display.

Five groups of settings can be easily recalled from the instrument’s front panel. Simply long press to store, short press to recall.

In constant voltage mode, the output current is lower than set value, the channel indicator will be green (CV), and the voltage keeps as set value. If the output current reaches the set value, the device will switch to the constant current mode. In constant current mode, the channel indicator will be red (CC). The output current is equal to set value and the voltage is lower than set value. If the output current is lower than the set value, device will switch to the constant voltage mode.
