Two individual digital outputs for dew strips

DewZap has two individual digital RCA outputs. You can control each output by turning the knob on the side of the controller.

These outputs can also be used for telescope fan control or a lightbox.

LED Operation indicator

A led light for every dew channel on the front of the faceplate indicates the power intensity.

Pulse Width Modulation Duty Cycle Control

Controller was built with modern digital electronics and fully supports duty cycle % (PWM) control.

Zero to 100% heater control

Knobs can drive Pulse Width Modulation duty cycle from zero to 100%

Ten (10) amps of current capacity
(5 amps per channel)

Powerful MOSFETs on each output provide up to 5 Amps per channel.
There are no voltage drops there.

Reverse polarity protected.

The device is protected from reverse polarity.
