Question from customer: “I'd like to order a 220v electric hoist to raise and down a bridge boat with a remote control. The ascent and descent should be done when someone is still pressing the remote control button, as there is no stop. What would you like me the most suitable product? Thank you in advance." Answer: We recommend the ac 100V~240V momentary motor controlling model (S1FM-AC220& CV-2-2). It is specially designed for motor controlling because two relays are inserted inside. One relay is used for motor rotating towards “UP”. Another relay is used for motor rotating towards “DOWN”. There are “UP”, “COM” and “DOWN”contacts from output terminal. This kit can controls motor of rolling blinds, doors, projection screens, awnings, pumps, conveyors other appliances and mechanicals. The transmitting distance is usually about 500m in the open air. Wiring: Connect live wire to terminal “L” and neutral wire to terminal “N”....

Question from customer: Hello, I have a question about your products and a system I’m attempting to build. I have four sensors that give off about 5 volts when activated. When a sensor is activated I want to transmit a signal to a light and turn on a light. The basic design is: Sensor —> Transmitter  –>(Wireless)–> Receiver —> Light What I’m asking is what transmitter could I use with the 4 Channel Receiver? Would I need 4 separate transmitters for each of the sensors? Answer: We recommend the low current triggered transmitter (CB-2V) and the ac power direct output receiver (S1X-AC220). The transmitter is triggered by DC power 5~28V input. If low current input triggers transmitter, the transmitter will send RF signal to receiver to indicate it to work. The receiver has 1 Channel AC 110V/220V Power Output terminal contact. You don’t have to supply addition power to controlled device because the device will get power from powered ...

Question from customer: I use a manual switch to control 4 9V motors of my electron microscope and each motor works in 150ma (0.15a). In addition, only one motor works when I press button of remote control each time. Now I want to remote control them, have you got any suitable remote for me? Electron microscope: Manual Switch of microscope: Answer: We thought this 8 channel rf remote transmitter & receiver is very suitable for you . It can be used to control at most 8 on / off electrical devices. With characteristics of strong anti-interference, reverse power protection and over current protection. Three voltages dc9v, dc12v and dc24v are provided to choose. It is widely applied to control many kinds of lights, electrically operated doors / gates / windows / blinds and so on. It works with 8-button transmitter and their transmitting distance can reach to 500m. This is the wiring diagram. Wire each motor to the normally open terminal “B”. According to the diagram, you c...

Question from customer: I’m looking for a wireless remote that I can use to create a simple on off switch to 12 led light fixtures connecting to a 12V battery at different places around my home. Do you have a recommendation for which Wireless remotes or RF transmitters may be the best for the task at hand? Answer: We recommend model 12 Channel DC12V Remote Controller – 1 Transmitter & 12 Receiver (12S1UB-DC12&1CV-12). This RF remote controller has the special ability to learn remote codes, allowing it to be used in one-transmitter-to-many-receivers system. That is to say, you only need a transmitter to control 12 receivers. It operates in toggle, momentary, and latched mode (set the mode as you like freely). It is great for hard to reach lights or other DC/AC electrical devices, remote distance can be 500m (theoretically). And it is applied for controlling lights, motors, fans, electrically operated doors / locks / windows / blinds / cars or other appliances with voltage A...

8 channel rf remote transmitter & receiver operates in 8 working modes. It can be used to control at most 8 on / off electrical devices. With characteristics of strong anti-interference, reverse power protection and over current protection. Three voltages dc9v, dc12v and dc24v are provided to choose. Widely applied to control every kinds of lights, electrically operated doors / gates / windows / blinds and so on. This video aims to show how to control 2 AC motor.
