Kendrick Dewminator 4-Channel Dew Controller - Kendrick new mid-level controller is the perfect choice for those who are budget conscious, but still want more than basic features.

Dewminator features 4 individual adjustable heater ports and dual DC Accessory Ports that can power other 12V equipment.

Product Features:

Heavy-Duty, individually adjustable power output for up to 4 heaters.
2 DC Accessory Ports
15 Amps total power (max 7 Amp with Cigarette Lighter Plug).
Dimmable lights! In fact, after 20 seconds, they shut-off! Turning any knob will "wake-up" the lights again.
User Changeable Cord.
Cord Management - Power other devices using the 2 DC Accessory Ports. For example, our 12V USB Hub.
Low Voltage Cut-Off - A Kendrick Standard that saves your battery from permanent destruction.
Disable Low Voltage Cut-Off. We don't recommend it, but if you want to drain your battery beyond repair it is now possible.

Anderson Power Pole Option: All Kendrick Dew Controllers include a power cord with that uses a Cigarette Lighter Plug with an internal 7 Amp fuse. Some astronomers prefer Anderson Power Pole Connectors which are superior to cigarette lighter plugs. We also terminate the power cord with a special "pluggable terminal block" which makes it easy to make your own power cord. For convenience, we offer 2 Anderson Kits that include the Red & Black plastic shells and 2 metal contacts. The "Pre-Welded" model permanently fuses the plastic shells together using a plug orientation that works with Kendrick Power Supply/Distribution products. If you are unsure of the plug orientation you need, purchase the "non-welded" model.

Extra Power Cords are available. The controller does include a power cord, but some people like a spare cord and they are available for purchase.
