There are control panel, remote control, the number of power cord.
There is an electric curtain (curtain) of the motor power is generally 45W, the maximum is about 90W, so do not use too thick line, 1.5 square on the line
Before the opening and closing the rail and the use of transformers, converted to 24V volts dc. The opening track used less and less.There is a direct control of the use of direct power supply motor, directly into the central control system through the relay, the use of the central control system into a unified control of weak;
Power supply direct control of the motor power line is the four core of the sheath line, 220V, the power supply line of the controller is the three core of the sheath line; if it is built in the receiver motor, the power line of the motor with 3 core sheath line;
