The Pegasus Astro DewMaster was made for visual astronomers and astrophotographers. 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 device quick and simple to control. Monitor the consumed Amperes and Input voltage on the display.  An external sensor will let you know the levels of the relative humidity, temperature and dew point. The temperature sensor also allows automatic dew heater control. Relax as your DewMaster keeps your optics moisture free!

Five channels, Five RCA Outputs

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. DewMaster can auto adjust the heater power levels by consulting the environmental sensor Just long press the knob to select“Auto” and leave to device decide if it is time to turn on and precise tune the power levels of your dew heaters.

Organic LED Display with Red Film

A 128 x 64 pixel Organic LED (red film) screen is used for the device. This display works lag-free, at very low temperatures. The red film on top of the display ensures that your night vision is going to be unaffected.

An External Environment Sensor is included

An external one (1) meter high-resolution temperature & relative humidity calibrated sensor will let you know the environmental conditions of your site. The sensor can be auto combined with the dew heater outlets to automatically adjust the power levels.

Leave it to the DewMaster to decide if it is time to turn on your heating elements! You can also monitor the readings of temperature, humidity, and dew point on the display screen.

Two pass-through DC outputs

Two 12V outputs let you connect additional equipment with less and shorter cables. The device also includes an Amp-meter which displays the total current consumption of the device, DC outputs, and dew heater channels.

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.
