Product description

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!

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.

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!

Reverse polarity protection: The device was designed to be protected from reverse voltage polarity. No worries if you accidentally reverse connect your power source.
