Celestron POWER CONTROLLER 4X

To Next Page

ENGLISH | 1

Congratulations on purchasing the Celestron Smart DewHeater

and Power Controller 4x. This controller delivers “smart” and

efﬁcient power usage for up to four of your telescope system’s dew

heaters and up to four 12V DC devices while also providing cable

management for your setup. Plug all your dew heaters, power cables,

and USB cables into the controller. Then you can use one cable to

connect them all to your power source and another to connect them

to your PC, if desired.

If you prefer not to connect to a PC, simply plug your dew heaters

into the controller and power it on. The controller will automatically

monitor the ambient temperature and humidity using its integrated

environmental sensor. The thermistor port monitors the corrector

lens’ temperature and provides only enough power to prevent dew. If

you’re using battery power, this “smart” system signiﬁcantly reduces

the heaters’ power consumption, extending battery life. If you would

like to manually adjust settings or monitor data, connect to a PC or

your Celestron mount’s hand control.

Please read through this entire manual before attempting to use the

Smart DewHeater and Power Controller 4x.
