R-Sky has released an updated version of their R-Sky Automatic Controller for controlling dew heaters. Among the updates are a new case, a more convenient power connector and more. The controller provides precise automatic temperature control as it uses sensors to constantly track changes in air and telescope temperatures and turns on automatically to keep your optics free of dew and moisture.
The R-Sky Automatic Controller acts as a “switch on and forget” device. Just connect the air sensor and the telescope sensor, set the desired temperature range that prevents dew from appearing on your lens (corrector, mirror, etc.) and that’s it. There is no need to worry about power settings and the controller is very easy to use with no complex controls that need to be worked with in darkness. Just turn the knob and forget about dew.
The R-Sky Automatic Controller uses pulse-width modulation to save energy. With its advanced automation features, it only turns when it’s really necessary and does not drain the battery. When the battery’s voltage approaches the critical level of 10.5V, the controller will start producing a regular signal while gradually increasing the brightness of a yellow LED on the faceplate.
The controller can simultaneously heat up to 2 optical tools in automatic mode, such as two telescopes or a telescope and a finder (or guider), secondary mirror, etc. There is no CCD interference and the unit offers reverse polarity protection
If you don’t need automatic temperature control, simply unplug all the sensors from the controller and you can change the temperature manually. The knob that is used for setting the temperature range in automatic mode also functions as a gradual power adjuster that allows you to control the power in the 0-100% range for output (1) and output (2). Outputs (3) and (4) will still be in the medium power mode, and outputs (5) and (6) will be at full 12V.
The R-Sky Automatic Controller specifications include:
– Line supply: 12V, DC
– 6 outputs: 2 automatic control, 2 medium power, 2 full power (12V)
– Max. current per channel: 3A (total 5A)
– Pulse-width modulation duty cycle control
– The standard power cable length is 120 cm terminated by a cigarette lighter plug
