Wiring free switch+TUYA intelligent curtain controller can easily realize remote multi-control
Wiring free switch+curtain controller package, wiring free multi control graffiti intelligent curtain controller.
It supports the use of Ebelong spring-back self-powered wiring free switch (2 keys and above) to control the forward rotation, reverse rotation, and stop of the curtain motor. The controller supports two control modes and the reverse control function of the motor.
Applicable motor type: curtain opening/closing motor, roller shutter motor.
1. It is suitable for installation in scenes that are inconvenient for wiring, such as glass, partition, and scenes that require fixed switches and multiple controls (office buildings, business summer, etc.)
2. No battery maintenance, long control distance, free installation, waterproof.
3. Support mobile phone control and voice control
4. Accessible to the smart home system
Application example:
Wiring mode
(1) Weak current mode wiring
(2) Strong current mode wiring
Technical advantages
Zero-crossing protection technology
The controller generally uses a relay as the “switch” control element, and the contact is the most important component of the relay, and also the most vulnerable part, especially in high-voltage and high-power control systems. Contact sparking occurs at the moment of contact closure, and arcing occurs at the moment of contact disconnection, causing contact damage, and leading to control system failure or serious consequences. When the contact of the relay is disconnected, if the load is nonpure resistance type, it will generate reverse electromotive force. The air between the contacts will be broken down, forming arc discharge. The high temperature generated will burn the contacts, greatly reducing the life of the relay. In addition, the electromagnetic wave interference generated by the arc will also affect the normal operation of the accessory electronic equipment. If the contact is disconnected just when the load current passes zero, In this way, the reverse electromotive force generated is minimum, and the arc discharge can be reduced. During the design of the intelligent switch, the zero-crossing protection circuit design can significantly improve the service life of the product.
The Ebelong controller adopts the voltage zero crossing protection technology, which can eliminate the instantaneous large current impact and effectively prevent the current overload when the thyristor element starts, greatly extending the service life of the switch controller, and can play the role of protecting the bulb.
