TECHSUPREME W1209 thermostat module has a temperature sensor, keys, LED display, relay and requires DC 12V power supply. It is an affordable, good quality thermostat controller. Thermostats are devices that sense the temperature of a system so that the temperature is maintained at the desired set point or near to it. NTC temperature sensor allows the module to intelligently control varied electrical devices based on the temperature. The relay can operate at voltages up to a maximum of 240V AC at 5A or 14V DC at 10A to power on. The temperature is displayed in degree centigrade and with the help of 7-segment display and the relay, the state is displayed with the help of the LED present on the W1209 module. Specification:- Temperature Control Range: -50 ~ 110°C, Resolution at -9.9 to 99.9: 0.1°C, Resolution at all other temperatures: 1°C, Control Accuracy: 0.1°C, Refresh Rate: 0.5 Seconds, Input Power (DC): 12V, Waterproof Sensor: 0.5M, Output: 1 Channel Relay Output, Capacity: 10A AND This is a fairly large, 12V operated fan. Axial fans blow air along the axis of the fan, or parallel to the track of the blade axis. DC axial fans are found in a variety of applications, including computing, servers, telecommunication cabinets, and any type of equipment where the need for thermal control is necessary for the improved reliability and life extension of the components that are included in the system. Uncontrolled heat generated by electronic devices will not only decrease the performance of any system, but will ultimately lead to complete system failure. In order to prevent this catastrophe from occurring, it is imperative that your equipment be designed with an efficient cooling system in mind. This system will not only be crucial to heat dissipation but will also contribute to the stability and long life of the equipment itself. This is where a DC fan with a well designed cooling path becomes one of the most important components of any equipment. Heat dissipation for the prevention of premature failure is by far the most crucial part of any electronic system design, and a DC fan is one of the best tools available to keep your electronic devices performing at top operational shape. DC fan functions best under a low pressure or low system impedance environment. With reduced fan speed the noise produced by an axial fan can be kept at a minimum. 100 percent Brand New Excellent Quality Short Circuit, Over Voltage and Over Current Protection.

Replaces lower amped adapters 12v 0.5A 2A. 1.5A etc. Smart Replacement Gadget Power Supply for LED, SMD, LED Strip, RGB LED Strip Ideal for Routers or Modems or Mobile Phones or Mp3 players or POS Machines etc. Best for Routers, Wi-Fi Routers security or spy camera receiver and some advanced cameras CCTV, Gadgets, Portable Players, Set Top Boxes, best for Toys etc., Charging or any gadgets as per the rating of the device, please study and then buy as this a very technical item only works as per its precise current outputs This power supply is an ideal replacement for a wireless network router such as the Netgear DG834, DG834GT, DG934 etc. plus a range of many other wireless routers. You will need to check the DC socket size and power rating with the supplier of the router you are using as we can not confirm it will work. Please do not ask us as we are unable to verify this kind of information due to the large range of routers currently available on the market. This power unit s also suitable for any other equipment requiring a 12 volt DC supply up to a maximum of 2 Amp. Package Include: 1 x Power Adaptor 12 Volt 2 Amp
