Title:
ENERGIZING CIRCUIT OF A MAGNETIZING COIL OF AN OPERATIONAL BRAKE, A PASSENGER CONVEYOR, AND A METHOD FOR ENERGIZING THE MAGNETIZING COIL OF THE OPERATIONAL BRAKE OF A PASSENGER CONVEYOR
Document Type and Number:
WIPO Patent Application WO/2016/150714
Kind Code:
A3
Abstract:
The invention relates to an energizing circuit (50) of at least one magnetizing coil (28) of an operational brake (1), the energizing circuit being configured for energizing the magnetizing coil (28), which energizing circuit (50) comprises a rectifying bridge (D2) connected to the supply network, the output terminals of the rectifying bridge being connectable/connected to the input points (BR+, BR-) of the magnetizing coil (28), characterized in that the energizing circuit comprises at least one reduced voltage circuit or external DC supply, whose outputs are connectable via to the to the input points (BR+, BR-) of the magnetizing coil (28) via a controllable operation switch of the energizing circuit. The patent application also comprises claims for a passenger conveyor and for a method.
