Overview: I’m looking for a High power remote controller to switch on/off the power to my children’s “John Deere ground force” 12v tractor if necessary. According to the specifications on the tractors the motors are 330watt and are driven by 12v battery. 330/12=27.5 amps. So I guess I need a 30amp controller. Solution:         We recommend the model of 1 channel 30amp 12V remote controller (S1PU-DC12&C-2). Its maximum current output is 30amp. It is suitable for appliances with AC110~240V or DC0~28V because of its normally open & closed relay contact. There are 3 working modes in it. The transmitting distance is about 100m (300ft). It is enough for you. You can see its wiring diagram. We suggest that you should learn this wiring way. That will be much convenient to you. Wire tractor’s motor to “A” terminal and negative terminal of receiver. Use a wire to connect “B” terminal and positive terminal of receiver. And wire positive and negati...

Question from Customer: I’m looking for solution to remotely control fireplace chimney fan on roof of hi-rise building. Desired range would by over 150- 300ft. Fan is 110v, around 2A. Power source would be on roof and antenna would be on roof. Please let me know if you have hardware solution. Answer: 1 channel 30A long range remote switch (S1PX-AC220-ANT2&CB-2) is very suitable for you. With 30A current and AC100~240V voltage direct output, you don’t have to provide additional power supply to controlled fireplace chimney fan because it can get power from powered receiver. The receiver is installed a external extend magnetic antenna, it will help receiver to amplify RF signal reception so that its working distance can reach 2000m(6000ft) outdoor. It is applied to hi-rise building and long range between two buildings. The transmitter enhances its transmitting function to match this kind of receiver. The wiring procedure is simple. Look at the following picture. Wire fan’s mo...

One customer said he would like to install 6V led lamp into the trunk of his car and wants to control it by remote controller. He is wondering if it can come true because he wants to use LED lamp to illuminate with use of 6V battery. We recommend him 1 channel 6V latched remote control kit (S1L-DC06+C-2). This kind of remote control kit is activated by 6V power supply. So he doesn’t have to supply additional power for led lamp because led lamp will get power from powered receiver as long as you wire lamp to the receiver. With latched mode, he can press button 1 of transmitter to turn on led lamp and press button 2 of transmitter to turn off led lamp. If he wants to set on / off function respectively, it is better choice. It has normally open and closed contact. It controls various lights, fans or motors with voltage AC110~240V or DC0~28V. Of course, if he wants to remote control alternate current device, he needs to do some different wiring from direct current device. Here is the ...

Question from customer: I need a radio system for switching a receiver of an underground garage, by a concrete slab with steel reinforcement and about 30 meters Distance 1st floor. The receiver may be 220 volts. Transmitter I want to act with an external contact. (Connection to a car alarm system). Answer: We recommend the 1 channel high power receiver (S1PUA-AC220-ANT2) and long range transmitter with extended wires (CB-2N). The receiver is activated by ac 220V, which is about 2000m working distance with external extended antenna. The wireless RF signal can pass through walls, floors and doors. It works with the long range transmitter, which features in two external wires because connection of two wires is its triggering method. According to your requirement, we drew a wiring diagram. Wires on the transmitter should be connected to the contacts of car alarm system. The normally open contacts A&B of receiver should be connected to the garage door motor. And supply additio...

The 1 channel Latched mode RF remote control operates in AC110V ~220V and 315/433MHz. Through retrofitting, this kind of remote control made a little changes compared with the original remote. Two kinds of receiver style, one is AC 110V (AC 100~120V), widely used in US, Canada…; the other is AC220V (AC 200~240V), used in UK, France…. The Coding type of receiver is learning code. Maximum working current for each channel is 3 ampere instead of 4 ampere of original one. The working distance is 100M. You can control on/off, open/close of universal electrical devices. Applications include gate remote control, motor remote control, garage door remote control, light remote control, etc. We will take ac light remote controlling for an example. Look at the following wiring diagram. From the interior analogue circuit, we connect the neutral wire to the terminal “1”, and the live wire to the terminal “2”. And then connect the lamp to the terminal “5” and the neutral wire. Latched mode is the ...

Someone is interested in controlling an air compressor remotely. The air compressor is 12v dc and 20 amps.He wants this to be a long range remote control system with the ability to accommodate a heavy duty compressor. He only wants the remote control to have the “on” and “off” functions for this air compressor. As we know, air compressor is a device that converts power (usually from an electric motor, a diesel engine or a gasoline engine) into kinetic energy by compressing and pressurizing air, which can be released in quick bursts. It is used for sanders, sprayers, nail guns or almost any other types of air tools. Definitely, remote controlling of air compressor is really an easy task, you can switch it on and off from a reliable distance. So we recommend this 1 channel 30A long range remote control (S1PU-DC12-ANT2+1CB-2) to you. Maximum current of channel is 30amp which is very favorable for your air compressor. With external extend antenna, the transmitter and receiver...

One of our customers wants to control 6 dc motors with transmitter. Each two buttons can switch every motor to rotate from different direction. That is to say, one button to make motor run one direction, another button to make motor go in the other direction. He is wondering if our product can satisfy his need. Here we recommend this model— 12 channel dc remote control switch (S12CA-DC09/12/24 & CV-12) includes one 12-button remote transmitter and one 12-channel receiver. Each remote button controls each channel of receiver on and off. It can be used to control at most 12 same or different on / off electrical devices. But it only can be used to control 6 motors for every two relays in the receiver can control one motor to rotate in forward and reverse. Remote distance is up to 500m. We will make a demonstration to this customer. First, we should prepare those materials. 1 x 12 channel dc remote control receiver (S12CA-DC12) 1 x 2-button remote transmitter (CV-12) 2 x dc12v ...
