The above picture is load expriement control circuit.The largest external load of this circuit can reach up to 10 A and it's widely used in the exprimental power supply,power amplifier, bearing capacity experiments of the LED and relay and solenoid. Different from the general resistance loading,it keeps the experiment load constant through regulating 1.2-50V voltage range's load current.Circuit adopts power MOS-an FET (VTl) and measuring resistance (RA a RD) to consump load power and the battery is used to isolate so as to solve the ground work. RP2 uses ten laps, which improves the precision and potentiometer resolution.
