DewMaster was made for the visual astronomer. Connect up to five dew heaters and control them individually using PWM duty cycle.
Full digital operation and a high resolution red film display makes the control of the device quick and simple. Measure consumed Amperes and Input voltage by a glimpse of an eye. Optionally, an external temperature and humidity sensor will let you know the levels of the relative humidity , temperature and dew point. Automatic dew heaters control will let you relax as you know that in case of high levels of humidity your optics will be moisture free!
Five channels, Five RCA outputs for heater attachment
Five powerful MOSFETs (supporting up to 6 Amps each) will ensure they will feed your dew heaters with all the required power. Mosfet transistors ensures no voltage drops in any of the outputs!
Pulse Width Modulation duty cycle control.
PWM control will let you reduce your battery’s power consumption.
Organic LED display with Red Film
A 128 x 64 pixel Organic LED (red film) screen is used for the device. It will ensure that your night vision will be unaffected.
Below images show the on screen display menus of the DewMaster.
External Environment Sensor ( * Included)
External one (1) meter high resolution temperature & relative humidity calibrated sensor. Know exactly the environment conditions of your location. The sensor can be auto combined with the dew heater outlets to automatically handle the power levels. Leave to the DewMaster decide if it is time to turn on your heating elements! You can also monitor the readings of temperature, humidity and dew point in the display screen.
* Environmental sensor is now included in the package at no extra cost – Please note that new sensor is in blue colour and is compatible with newer firmware only.
Two pass through DC outputs
Two 12V outputs let you connect additional equipment with less and shorter cables
Easy to Use
Just push down the knob and choose the desired output. Turn the knob (left or right) to control the duty cycle from 0-100%. Simple as that!
Full Digital Operation
The device is 100% digital operated.
Reverse polarity protection
The device was designed to be protected from reverse voltage polarity. No worries if you accidentally reverse connect your power source.
