XH-M452 Temperature Humidity Control Hygrometer DC 12V LED Digital Display Thermometer Controller High Precision Double Output Automatic Constant Temperature and Humidity Control Board


Super material:  It is made of electronic accessories element, inner conductor is pure copper. it is long lasting and durable for you to use, used to adjust output voltage between 50V-220V.
Ultra low voltage dc motor governor, with switch function. The product is suitable for self-recovery fuse, the current is too large and automatically disconnects, and the fuse is automatically restored after cooling.
PWM DC Motor Governor specification: The working voltage is DC 12V  Maximum output power: 2000W. The current is up to 25A. Potentiometer with switch function. 
High Power High Efficiency: The two relays are separately controlled, one way to control the temperature, another way to control the humidity. It is precise and reliable with good long-term stability. With fixing screw hole, convenient for install and fixed. Small size, low power consumption, fast response.
A wide range of applications: Suitable for electric stove, water heater tune thermal, lighting dimmer, small motor speed, electric iron thermostat, and achieve dimming, thermostats, pressure regulator effect, control cabinet constant temperature and humidity control, incubation and breeding temperature control, printing plant.
