First, let's introduce the power knowledge of the electric garage door.
A. DC standby power supply: refers to the standby power without inverter, the battery is charged by a high-power transformer with large current, and its working mode is: when the power supply is normal, the garage door opener equipment directly supplies power to the DC motor by transformer voltage rectification, at the same time, it also charges to the battery, when the power supply is disconnected, it can automatically switch to the battery power supply. But there is no reliable battery discharge protection circuit until the battery consumes.
B. Intelligent DC storage and power supply system: Garage door motor refers to the backup power without inverter, and the storage battery is trickled and charged by switching regulated power supply. Its working mode is: whether the power supply is normal or not, the motor uses the current in the storage battery, which makes the battery plate always in the active state. Standby transformer voltage converter rectifier to the battery trickle charge, when the power is disconnected, can automatically switch to battery power supply, and has a reliable battery charge, discharge protection circuit to avoid battery consumption.
Two. Installation position of power supply for electric garage door
The motor outlet of the electric garage door is usually about 1.5 meters. The power of the garage door motor is generally different from 80w-500w, so the power cord can be set to 2.5.
A, turnover garage door
The motor is in the middle of the garage, the power back in what position, according to the height of the doorway to determine, generally in the height of the doorway plus one meter should be almost the same, for example, the doorway 2.5 meters high, then the power installed in the middle of the doorway 3.5 meters behind the position.
B, rolling curtain garage door
Then the power outlet is installed on either side of the doorway to the upper position, away from the doorway about one meter away.
