4tronix 4-Channel Digital Dew Heater Controller
4-Channel Digital Dew Heater Controller
Microprocessor controlled, digital PWM dew heater controller with 4 independent channels, each capable of 4A.
This compact Dew Heater Controller can be powered from 7V to 15V and enables each channel to be controlled over the full range from fully Off to totally On.
Each channel has a red indicator LED that flashes at a rate indicating the amount of power being delivered to that channel, Totally Off indicates no power, continuously On indicates 100% power, slow flashing is low power and fast flashing is high power. (for those techie types, note that the flashing of the LED is not directly related to the PWM frequency or duty cycle - the PWM frequency is about 1kHz).
Power provided from the 2.1mm DC Jack input (centre positive)
