DewZap

Harness the power of precise dew control with the DewZap Dual Channel Dew Heater Controller, engineered by Pegasus Astro to meet the demanding needs of serious astrophotographers and night-sky observers. Whether you're imaging faint deep-sky objects or simply preserving view clarity through a telescope, DewZap delivers reliable, variable-power regulation to combat dew buildup during long sessions under the stars. Compact yet powerful, it provides two independently controlled digital outputs (via RCA) with full pulse width modulation (PWM) capability, letting you dial in anything from 0 % to 100 % power per channel. Each channel can push up to 5 amps, making this device robust enough for dew heater strips, telescope fans, or auxiliary devices like small lightboxes. With intuitive LED indicators and built-in reverse polarity protection, DewZap ensures safe, smooth operation through the chill of night. Perfect for astrophotographers, visual observers, and astronomy enthusiasts who demand a dependable dew management solution.

Key Features & Benefits:

• Dual independent digital outputs (RCA) — ideal for two separate dew heater strips or a combination of heaters and fans

• Full PWM (pulse width modulation) control from 0 % to 100 % duty cycle — enables fine-grain power adjustment

• High current capacity — up to 5 amps per channel (10 amps total) via MOSFET design, with negligible voltage drop

• LED intensity indicators — front-panel LEDs give instant feedback on each channel’s power level

• Versatility — outputs may also drive equipment like telescope cooling fans or small lightboxes

• Reverse polarity protection — safeguards your gear from accidental backward wiring

• Compact form factor (66 × 66 × 28 mm) — easy to integrate into your imaging rig

• Operates on 12 V to 13.8 V DC — standard for most astro setups

• Designed for durability and precision in demanding astro environments
