13.8V 30 Amp Power Supply Circuit LM338K
An amateur radio the radio for the design and applied 13.8V 30A power supply .. on the Internet a lot of similar application schema but this circuit detailed and more powerful writers trodial transformers have used the transformer input EMI filter and soft start circuit’s. In addition to the fan control circuit input, output fuse has LED indicators are provided with control LM338K regulator IC that can give 5 amp power MJ15004 power transistors 30 amp power has been increased by adding power
