UNI-T UDP 1306C DC Power Supply The UDP1306C programmable DC power supply is a cost-effective laboratory power supply featuring a main output channel and a USB charging channel. It is a basic power supply for users who require a smaller, highly reliable power supply. Compared to the higher-end (multi-channel) UDP power supplies, this model allows for a higher channel load, up to 6A at a voltage of 32V. The power supply contains a classic linear transformer and allows operation in constant voltage (CV) mode within the range of 0 to 32V or in constant current (CC) mode from 0 to 6A. In addition, there is a USB connector on the front panel, which can be used to charge, for example, a mobile phone at a voltage of 5V and a current of up to 3A. The laboratory power supply features an EBTN display with three high-precision indicators that simultaneously display voltage, current and power with 4-digit accuracy. The power supply has programmable parameters. It features 5 memory slots for easy storage and recall of set modes, and a lock button to prevent unwanted changes to the parameters. On the rear of the power supply housing are USB-Device and RS232 connectors, and a DIGITAL I/O interface for remote control of the power supply. Using the supplied software, it is possible to record and display the consumption or load characteristics of the connected load in real time on the connected PC in an Excel spreadsheet or graph, and communication with the computer can be carried out via SCPI commands. Regular calibrations can be performed via the software.
