Output voltage Range Of Difference:?1%Efficiency: 83% ?ADJUSTABLE Voltage and Current?Input voltage: AC 110V / 220V (85-145V / 185-265V); Output current depends on the device, e.g.DC 12V 10A 120W, 20A 240W, 35A 420W, and the peak current is 50A, peak power 600W. Recommended for equipment below 40A 480W. For resistive device, SMPS peak power ? device power 1.25 times. For Motor device, the peak power of the SMPS needs to be more than 2 times the power of the Motor. ?One-Key Operate?With red button on/off switch function, more safe and convenient power start/stop operation, Switch Transformer build with Imported Aluminum alloy shell ,Built-in wire integrated design, Dual power connection methods. ?Safety Features?Automatic overload cut-off, over Voltage cut-off, automatic thermal cut-off, short circuit protection.High Reliability, Low Temperature Rise,Built-in EMI filter, 100% Full load burn-in Tested. ?Includ Clamps and Copper Wire?12V 50A 600W Power Supply converter with ul power cord ,wire lugs, metal clip and screw. Dial to the correct gear position, cut off the power before disassembling the connection ?Applications Widely?Simultaneous power supplies for devices different currents/watts.
