SMSCom 4.5amp Twin Fan speed controller

The SMSCom 4.5amp Twin Fan Speed Temperature Controller is a slender and compact version of the ever-popular SMSCom Twin. Not only that, it’s also cheaper and comes with an IEC power cable and socket, making it easier to switch to longer cables if required. The most popular model in the range just got even better!

  • SMSCom – Great quality and value-for-money
  • The MK2 (latest) version of the most popular model in the range!
  • Gives great control over your Grow room air temperature
  • Controls the speed of both an intake fan and an outlet fan
  • Maintains a user-set temperature in your grow-room via an external temperature sensor
  • Allows the user to set a minimum fan speed to ensure adequate air exchange even at low temps
  • Maximum fan speed setting – great for using oversized fans
  • Supplies 2 outputs up to 510 Watts (2.25 Amps) each

Please note: though digital fan speed controllers (like this one) are a very cost-effective solution, they may generate a humming sound. This is an unavoidable consequence of using pulse width modulation to regulate fan output. We highly recommend SMSCom Hybrid Fan Speed Controllers, which instead use heavyweight transformers and run completely silent.
