For example, if the max current of your load device is 10A, then choose 10A/0.8=12.5A at least for resistive loads according to international standard. If the load device is motor or compressor, then you may choose 10A/0.5=20A according to real testing result since the motor and compressor starting current may be 2-3 times than nominal current. ## Features - Input voltage range: DC 10-30V; Output voltage: DC 5V(non-adjustable); Output current: 40A; Output power 200W. - High conversion efficiency: Synchronization rectification technology-multiple intelligent protection function with high conversion efficiency and stability.
