In this video, I reviewed UNI-T's UDP3305S programmable DC power supply. Product link: uni-trendus.com/products/udp3305s-4ch-performance-series-programmable-linear-dc-power-supply

This is a four channel linear power supply which offers two main independent output channels which can output 0-33V and 0-5.2A, these two channels can also operate in parallel or series modes. A third channel can output up to 6.2V with a maximum output current of 3.2A. The fourth channel is a 5V 2A USB port.
