Astrozap Dual Channel Controller
The Astrozap Dual Channel Controller uses pulse width modulation (PWM) 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 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 to limit the current drawn to 5 A, per the unit's design specs.
The Astrozap dew controller can be used to power their Flexi-Heat dew shields and Heat Bands. The RCA output connectors will accommodate other brand's of dew heaters.
The red power LED indicates that the controller is getting power. The two red lights by the outputs indicate (visually) the power level of each channel. The brighter the red LEDs, the higher is the duty cycle setting 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 so it stays off the ground.
