SMAKN&reg; DC-DC Convert 5-30V to 1.2-30V 10A Step Down Power Apply High-Power Constant voltage constant current Module Properties: non-isolated buck synchronous rectification module automatically Input voltage: DC5-30V;Input current: 8A (MAX) peak 10A (6A work a long time) Quiescent current: 4mA (operating voltage is not the same there will be errors) Output voltage: 1.25-30V continuously adjustable (the default output 12V, For other voltages, please take notes at the time.) Output Current: 10A (MAX) (long natural heat inside 5A) For higher output current, two modules can be used in parallel, such as output is 10A, two modules can be connected in parallel, the current per module transferred to 5A can be.
