3pcs ZHIYU DC 12V 5A PWM Fan Speed Controller Regulator Temperature Control Board With Buzzer+Probe

Description:

1. The use of synchronous rectifier converter design, high efficiency, high current work doesn't require additional heat sink, the output is smooth DC (no pulse), direct drive output design.

2. Can support all 12V 5A within the fan, including brush DC motors, pumps, light bulbs, etc. Can't exceed the maximum current conditions can work more than one fan in parallel, a soft-start power.

3. Can be adjusted by rotating the board any manual speed control resistor.

4. With four-zone automatic temperature control variable speed function, plug in the temperature control probe automatically after the entry into force, temperature control will manually adjust the speed to the lowest speed, the highest speed is 12V through. The linear speed of the middle speed change.

5. With the work monitoring function of a channel, can support a way with a speed wire (such as three-wire fan) stop monitoring alarm, when the speed is less than 450 rpm sound and light alarm (need to be equipped with buzzer).
