The SK-40 cameras stabilizer is designed to powering the camera with or without a thermostat.
The SK-40 operates with the ZK-40/16 power supply adapter, which is designed to deliver ca. DC 40V voltage, which is then stabilized down to DC 12V voltage in the SK-40 device and enables powering the camera with or without a thermostat.
Presented here power supply solution, compensates the voltage drops on the cable and enables powering the cameras up to several hundred meters distance.
