The SP-1305D linear DC power supply has a single output channel and 4 digit LED display. With a linear copper transformer, the relay converts the secondary output voltage with high efficiency. Features an intelligent cooling fan that adjusts its speed according to temperature to reduce noise and prolong the life of the power supply. It has a pure DC output along with low ripple and noise, making it an excellent choice for use in schools, charging batteries, and burn-in testing of electronic products.
