Including both variable output voltage and current this bench power supply is an ideal addition to any work bench. Voltage is fully variable from 0 – 30V on the main terminals, plus auxiliary outputs of fixed 12V and 5V at 0.5A are also provided. The output current can be set as desired up to 5A. If the load tries to draw more than the value selected, the power supply will shutdown. This is a very useful function as it can prevent damage to the load. Great for R+D, workshops, repair centres, etc.
