The UDP3000S Series is a high-performance programmable linear DC power supply. It has a clear LCD user interface, excellent performance indicators, a variety of analysis functions and communication interfaces. It can meet the diversified test needs of users. It aims to provide cost-effective DC programmable power supply equipment for teaching, scientific research, industry and other fields.

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 UDP3305S features a 4.3 inch high definition screen, which can display the current set output voltage/current, actual output voltage/current and protection output voltage/current value of the power supply in real time. The functional interface is simple and comprehensive, easy to operate.

The series-parallel connection between CH1 and CH2 of the main channel can be realized without external connection, which simplifies the connection and makes the test easier.

The UDP3305S provides 5 sets of output presets that can be freely edited and stored. Users can set the voltage, current, limit voltage and limit current parameters of each channel and series and parallel channel in advance, and load the parameters when using. This avoids the step of resetting parameters every time when turning on the instrument.

UDP3305S series power supply has waveform display function, which can display the output voltage, current and power of each channel on the screen.

When each channel operates independently, voltage, current and power waveforms of three channels can be displayed on the screen at the same time. When CH1 and CH2 are in series/parallel mode, only the waveforms of CH3 and series/parallel channel can be displayed simultaneously.

The trigger can be used as a trigger source to output high and low level signals to the external instrument, or as a source under control to trigger the on and off of the instrument output through the external input level. When triggered by an external signal, the trigger operates in trigger input mode. When the digital I/O interface detects the trigger signal, the power supply controls the channel action. When the external instrument is triggered, the digital I/O interface outputs high or low level signals when the trigger conditions are met.

The digital I/O interface on the rear panel needs to be connected, and the high level of IO input should not be higher than 3.3V to avoid damage to the instrument.

This series features USB, LAN and RS-232 interfaces. It supports SCPI general protocol and is equipped with host computer software, which can set, view and carry out statistical work on PC.
