FEATURES OF TCA TYPE TIAN CHERNG ELECTRIC CONTROLLER FOR ROLLING DOORS
*High-efficient motor is adopted
Equip with a heat thermostat device. When temperature is over 100℃, it can automatically cut off power to protect itself from burning up.
The 6-pole motor having lower rpm than ordinary motor sensors smooth and stable operation, As a result, noise caused by oscillation is relatively reduced.
Lightweight and compact size, can be easily constructed with less labor cost.
*Strict quality control
Composed of 2-step spiral gear, the speed reducer is made of special steel and undergoes heat treatment along with frequent inspection of hardness of gears. Every set undergoes an in-house inspection including passing a “complex test stage” of electric controller for rolling doors device before delivery to ensure its quality meeting the requirement of CNS and first-rate products.
*Patent brake system
The uniquely-designed dual-side brake system can produce double braking power, in the brake cap is mounted a specially-designed coil carrier inserted in order in moveable brake plate, brake disc, fixed brake plate and U-shape ring. One end of the spring stays against periphery of the moveable brake plate, and the brake disc can move along the axle of the motor so that brake force won’t be effect even when the brake pad is worn out.
A conventional brake is controlled by a manually-operated chain. In case of the hand chain unable to stick chain pitch, the rolling door will side down. Another case is that when the brake pad on an old brake disc is worn out thus gap is caused, the shutter lath will uncontrollable slide down when door is on.
*With a manual switch
In case of power failure or emergency, lightly pull dropping rod and the rolling door table drops to the required position. Top pull the “had chain”, the transmission gear can automatically engage and the door slowly moves up.
*Special safety device can be installed
A special safety device can be installed. Upon customer’s request. This device can cut off power when the “hand chain” is on.
