The switching power supply 12V 7.5A is built with the latest power supply technologies and the quality components materials to enable high performance. It features resonant-ring valley-switching operation for high operating efficiency, green-mode power-saving operation for low no-load power consumption resulting in excellent energy efficiency performance. The ac dc power adapter 12V 7A provides constant voltage regulation with low noise. Opto-Coupled Feedback Enables up to 2% Regulation. The 12V power adapter operates at 80-kHz maximum switching frequency with excellent EMC performance. Efficient natural cooling thermal management enhances operating performance and reliability that allows the power adapter 12V to operate at full power at higher ambient temperatures.
