AI summary
A dual-voltage door operator control system comprises a contactor, a high-voltage connector, a low-voltage connector, a rectifier and a brake. When a door operator motor is electrically coupled to the low-voltage connector, the rectifier full-wave rectifies an external power source and then electrically energizes the brake. When the door operator motor is electrically coupled to the high-voltage connector, the rectifier half-wave rectifies the external power source and then electrically energizes the brake. Accordingly, the door operator motor can be connected to the high-voltage connector or the low-voltage connector according to the specification of the external power source provided at the site. Moreover, the invention is also further integrated with the brake of a single specification, and no matter whether the external power source is a high-voltage power source or a low-voltage power source, it can electrically energize the brake through the rectifier.
