STANDARD DEWBUSTER
DewBuster™ Controller
DewBuster
The Ultimate Dew Controller
Precision temperature control keeps you dew free all night long while your telescope performs at its best. Easy to operate, stingy on power, built tough and reliable, and backed with a no-hassle 5 year warranty. Compatible with all major brands of heaters and 12VDC and 13.8VC power sources. Output configuration may be customized to your needs. Heavy Duty Power Cord with Powerpole® quick-disconnect accepts pigtails to accommodate most power sources.
Built To Last!
Designed for those who want the best and want it to last a long time. After 20 years of production 99% of all DewBuster™ Controllers are still in service! RCA jacks solidly mounted in quality powder-coated aluminum case so plugging/unplugging heaters won't stress circuit board and lead to cracked solder joints. Short-protected heater outputs protect controller from heater defects. I maintain purchase records so your receipt is not needed for the no-hassle 5-year warranty which even covers damage from home-made or defective heaters. And unlike other products, after the warranty period expires your DewBuster™ Controller is repairable at very modest cost!
Uncomplicated!
Spend time using your telescope rather than fiddling with your dew controller. Color-coded heater outputs simplify connections. No confusing controls to struggle with, simply turn one knob and forget about dew. Red blinking night-vision-friendly LED's assure you that your heaters are working properly. No programming to figure out and no need to recalibrate the when switching temperature sensors.
Temperature Controlled!
One Temperature Sensor cable measures both air and telescope temperature. Simply turn one control knob to power on and automatically control heater slightly above the air temperature, preventing dew while maximizing telescope performance. Sensor clips to heater strip so you can easily move sensor between telescopes. Swapping temperature sensors has no affect on calibration so you can order extra sensors for each telescope and move the controller back and forth while never needing to recalibrate. No reprogramming required when sensor is not used, controller detects when sensor is not being used and automatically switches that output to Medium Power.
Stingy on power!
Temperature control doesn't waste battery power early in the night when telescope is cooling-down, applies just enough power to keep telescope from cooling faster than the air. Pulse Width Modulation (PWM) is efficient and synchronized heater outputs alternate current between heaters to reduce peak current and battery voltage fluctuations. Intelligent Low-Battery circuitry doesn't just shut off heaters, it gradually reduces power to heaters keeping your optics dew-free as long as possible while giving you time to switch power sources or conserve energy by unplugging less-critical heaters. And it will not allow your battery to run below the 10.5V battery manufacturers' recommendation.
