PegasusAstro DewMaster The original DewMaster controls five dew-heater channels independently using a rotary push knob and a red-film OLED display. PWM adjustment from 0 to 100% sets the heat level, while current and input-voltage metering show power consumption.

Heater and auxiliary power
The legacy manual recommends up to 5 A per RCA heater channel, although the hardware can reach 6 A. Two additional pass-through DC outputs are rated at 5 A each. The total input-current limit is 20 A; individual channel ratings cannot all be used simultaneously above that budget.
Automatic dew control
An external temperature and humidity sensor allows the controller to regulate heating automatically from the environmental readings. Temperature, humidity and dew point can be viewed on the display.
Legacy model connections
The original model uses a 2.5 mm centre-positive power socket, distinct from DewMaster2’s 2.1 mm input. Recommended supply is 12–13.8 V DC.
