PegasusAstro Dual Channel Dew Heater Controller DewZap

PegasusAstro Dual Channel Dew Heater Controller DewZap

DewZap is a compact two-channel dew-heater controller with independent manual adjustment. Each RCA output is controlled by its own knob, allowing separate heater levels for two optical components.

PWM power adjustment

The controller varies the PWM duty cycle from 0 to 100%, reducing average heater power as the setting is lowered. Each channel supports up to 5 A, with a total capacity of 10 A. Front LEDs indicate the output intensity.

Connection and size

Use 12–13.8 V DC through the 2.1 mm centre-positive input. Reverse-polarity protection is built in. The enclosure measures 66 × 66 × 28 mm. The outputs can also regulate compatible fans or light panels within their electrical limits.
