High quality 12V DC fan speed controller 5A maximum support

High -quality large- current fan speed controller, support for all 12V fan shop , 1.5A, 2.4A, 3A, 3.3A, 3.9A, 4.8A , and so fans can be used. ( 1 ) Operating voltage : 12-15V ( 2 ) Control Power: 60W ( 3 ) Adjustment range : 10 % -95 % ( 4 ) Rated current : 5A Note: If you want to use a governor drag more than one fan , you can put a fan on the need to take the subject of the current label together calculate the sum , as long as no more than 5A on it. The governor then sets up to 4.8A fan run one hour the temperature is only 45 ¡ã, unlike ordinary governor can adjust the fan following 1.0A , 1.5A adjustable fan run a few minutes to heat to 80 ¡ã. Note : the use of low-frequency PWM pulse converter model made , the conversion efficiency of 100% . However, due to the low-frequency signal generated by the fan must make a low-frequency current sound , then there will be a low-frequency sound , the low-frequency sound can not be eliminated . If you took more than a fan , it will be focused on the low- frequency current sound amplification , form another noise pollution, the low-frequency sounds can not be eliminated , if forced to increase the frequency of adjustment will lead to increased power loss and heat . We only equipped with two fan connectors , you can contact us for more interface gives you increased an interface 1 dollar . To add a few can give you a few , there is a large fan 4D and 3P 4P and other proprietary interfaces .
