This speed controller supports all fans within 12V 5A. Synchronous rectification mode output, high efficiency. Even if the high current does not require additional radiator. Multiple fans can be used in parallel (the total current is not more than 5A), which supports automatic temperature control and manual speed regulation. Temperature control speed with 4 temperature zones can be set, is convenient for all kinds of application environment. With open three line fan monitoring function (turn off alarm)

Specifications:

1>. When the manual adjustment voltage is very low or 0V, it is equivalent to shutting down the fan. Suppose the temperature control is running on the basis of shutting down. The output voltage increases linearly with the increase of temperature due to the accelerating temperature, while the fan needs to be operated at least 3-5V voltage. Therefore, the actual accelerating temperature (or referred to as the starting temperature) after shutting down the fan is higher than the acceleration temperature in the setting temperature zone. However, this may cause the fan to start and stop frequently when the heat source is small, leading to the high temperature of the heat source component. Careful use.
2>. More than 97% of the common fans are 2 pole signal fan. There are also 3 pole signal and 4 pole signal fans (rarely seen). For the 2 pole signal, if it is below 450 turns alarm. For the 3 pole signal fan, it is equivalent to less than 300 turn alarm.

Setting instructions:
(to be effective once each set is recharged):
1>. Temperature setting: set as follows:

2>. Stop alarm setting:
When the setting switch 3 is in the on position, the alarm function is turned on to stop the switch. Please monitor the three wire fan to find the position of the three wire fan pin in the middle of the output. When the fan speed is lower than the threshold, the alarm will be stopped until the fan speed is resumed. Please switch the switch to OFF (non ON) without stopping the alarm function.
