1, Overview: This kind of DC12 v-48 v wide voltage two-way remote control switch, switch power supply, a professional switching power supply management chip, power supply voltage stability, a complete solution resistance capacity step-down and make the power supply voltage is not stable, lead to the entire switch unstable phenomenon.The remote control switch adopts 30 a relay, can load a high-power electrical appliances, learning microcontroller decoding, can learn more remote control, simple operation supporting flexible;Toggle switch is adopted to improve the switch output work way, dynamic, self-locking, interlocking (point) can be arbitrary choice easy to use, another new way of manual work.Apply to multiple areas a variety of purposes;Reserved for the output data bits welding plate, can receive through short different solder joint location choice of the remote control buttons, convenient customer supporting various remote control that oneself like, to avoid the old fixed single design keys you can match the embarrassment of the remote control. Mainly used in garage door control, lighting control, electric door, remote control curtains, lifting equipment, motor control, water pump, projection screen elevator control and security industry and other fields, is easy to install, use the advantages of simple and safe and reliable. Specifications: Operating Voltage:DC12-48V Operating Frequency:315 MHZ / 433 MHZ Operating Temperature:-40C ~ +80C Receiver Sensitivity:-105dBm Maximum load: 3000 watts, rated load 1500 watts Learning code:jog/Non-Latched .inter-lock/Latched . self-lock /Self-Latched PCB size:92 mm * 65 mm * 32 mm Output working way:Through the toggle switch,jog, self-locking, interlocking 1, the top to the zero position for interlock 2, the top to the N position for self-locking 1, 2 are not up-pull for jog Third, learning methods Press the learning button for 2 seconds, the indicator light (indicating that has entered the learning state), release the learning key, press any key on the remote control, the indicator light flashes three times after that learning success. Note: The controller can learn fixed code / learning code and other 16 different encoding remote control, in order to clear the earliest out of the remote control. Fourth, removal methods Press and hold the learning key for about 8 seconds. The indicator light goes from long to flashing three times and then goes out, indicating the successful removal. Note:433mhz and 315 mhz are available ,315mhz will be sent out if there is no demand on frequency 3.
