Astrozap 720 Dual-Channel Dew Controller
The Astrozap Dual-Channel Controller regulates the heat on two separate channels for either one or two dew heaters per channel. Control dew formation on your corrector plate, finderscope, eyepiece, mirror...you can even keep your telescope hand controller or laptop warm! The Astrozap 720 controller runs on 12v DC and comes with a six foot cord that adapts to your vehicle's auxiliary power port or a 12v battery pack equipped with the proper receptacle.
The Astrozap dual-channel controller uses pulse width modulation technology. Each channel controls two outputs for a total of four outputs. Each channel is capable of a duty cycle from 5% on time at the low setting to 95% on time at the high setting. The Astrozap 720 dew controller is manufactured for operation on 12 volts DC and should never be operated with any other voltage. Total amperage capacity for all four outputs is 5 amps. The controller is supplied with a six-foot cord equipped with a cigarette lighter plug end. A 5-amp fuse is incorporated into the plug.
The Astrozap dual dew controller can be used to power the Flexi-Heat dew shields and Heat Bands. The RCA output connectors will accommodate other brand dew heaters. The green LED indicates that the controller is getting power. The two amber lights by the outputs indicate the power level of each channel. The brighter the amber LEDs, the higher the duty cycle for that channel. When the controller is set to the lowest setting, it is effectively off. A two-inch Velcro strip is included for mounting the controller to a convenient area of your telescope mount.
