Feature: 1. Convert Current: The general purpose of switching power supply is to convert alternating current (mains) into direct current, very useful 2. Safe And Stable: LED driver possess high efficiency, small size, wide application, safe and stable, strong interference proof 3. Multiple Safety Protection: This power supply provide overload, over voltage, over temperature, over current, short circuit protection 4. New Component: Made of full glass fiber circuit board, which is environmental protection, smoldering, high temperature resistance, long life, etc., and use new components 5. PFC 0.95: Provide air cooling, meet IP67 level. Come with high PFC 0.95, no flicker, more stable to use Specification: Item Type: LED Driver Type: AC DC power supply Modulation Method: Pulse width modulation (PWM) type Transistor Connection Mode: Single ended Input Voltage Range: 100-265VAC 47/63Hz Output Power: 300W Work Efficiency: 95 (%) Output Ripple Noise: 30mV Output Voltage Accuracy: 0.5 (%) Voltage Adjustment Rate: 5 (%) Load Regulation Rate: 0.5 (%) Safety Protection: Overload, over voltage, over temperature, over current, short circuit protection Working Temperature: -20~+50, 20%-90%RH (non condensing) Circuit Board Components: Use full glass fiber circuit boards (environmental protection, smoldering, high temperature resistance, long life, etc.), using new components Storage Temperature: -20~+75 10%-95%RH (non condensing) Waterproof Rating: IP67. Package List: 1 x LED Driver Note: Real power, but comprehensive temperature and current fluctuations and prolong the life of the power supply, the power should be reserved 2030%.
