Electronic Dummy Load Circuit. R5 47 ohms. The maximum input voltage is 24v for the load.
This 20 Amp Variable Power Supply Varies Its Output Voltage From 1 5 To 15 Volts And Is Based On The We Power Supply Circuit Electronic Schematics Power Supply from br.pinterest.com
Basically when you dial in a current level the electronic load circuitry will draw only that amount of current regardless of the voltage. L1 100mh 20 amp ferrite core inductor. Soldering all components except the transistors on to a matrix board is the fastest way to build this circuit it will be very easy because its simplicity.
Parts list for the single dummy load electronic load controller circuit.
We have to install a heat sink for the transistor since the transistors work in linear mode and dissipate a lot of heat. A 10 turn potentiometer controls the load and displays this in amps via the on board lcd. The maximum input voltage is 24v for the load. Dc diac db 3 big.
