JINGMAIDA Switching Power Supply 1500W 110-240V AC to DC 48V 31A 1500W Power Supply with PFC for Computer Project, LED Strip Lights, 3D Printer

-Input voltage:AC 100-240V(wide voltage automatic adaptation, no switching); -Power factor PF value 0.97/110V (100% in full load) PF value 0.95/220V (100% in full load); -Output overload protection:Overload protection ways for constant current limit flow pattern lock output current value does not rise, the output voltage with load increasing; -High temperature protection:PWM transistor heat sink temperature of 85 + / - 5% when shut off the output voltage, temperature to 75 + 5% for automatic recovery; -Output short circuit protection:Since the xs, short circuit back output; -The output over voltage protection:Overvoltage point 115% of the nominal voltage, over voltage protection lock, after will not automatically restore, need again when the power is cut off electricity; -Working temperature:25 degrees below zero - 45 degrees centigrade, overtemperature need to down load; -The cooling way:Automatic temperature control speed fan (blowing); -Weight:4.85LBS; Size: 11 X 5.5 X 2.6 INCH(L*W*H) One year warrant. High PF value:With active PFC power because, several correction PF value above 0.9 to Et utilization rate is high. Wide voltage input:Ac 110-240v wide voltage input, automatic adaptation no 110/220 switch. Constant pressure constant current Both can work in the state of constant pressure and can work in the state of constant current voltage current adjust alone.
