1.Description:
 The fan speed controller can be used to adjust the rotation speed of 12V server cooling fan. It has two interfaces, which are a power socket and a Type-C interface.

2.Feature:
 1>.The Type-C interface can be powerd by a power bank.
 2>.It supports 5V/12V input voltage.
 3>.The rotation speed can be adjusted from 0% to 100%.
 4>.It is exquisite portable.

3.Parameter:
 1>.Product Name:Fan Speed Controller.
 2>.Input Voltage:5V/12V.
 3>.Output Voltage:12V.
 4>.Power:12W.
 5>.Color:blue.
 6>.Work Temperature:-25℃~85℃.
 7>.Work Humidity:5%~95%RH.
 8>.Size:55*20mm.

4.Intructions for Use:
 1>.Firstly you can connect power cord of the fan with 12V, control line with PWM, ground wire with GND.
 2>.Secondly the fan speed controller should be connected to power supplies. You can select one of the two inertfaces to connect to. (However, because the Type-C voltage needs to be boosted to 12V, there will be losses, and the rotation speed of fan will be lower than that connected to power socket.)
 3>.Finally you can turn the potential regulator to change the rotation speed of fan.

5.Package:
  1 pcs DC 12V 12W Fan Speed Controller.
