The subject of the present invention is a static electronic panel for control of three-phase motors with rapid reversal of the direction of operation. It consists of the combination of a three-phase static electronic contactor with triacs, with very rapid reversal of the direction of operation by permutation of two phases, equipped with protection by electronic locking (3) with a dead-time generator (6) avoiding the short-circuit between phases, of a bidirectional, anti-overvoltage system and of a system for countering mains micro-failures. It is intended to equip any motorised systems for intensive use and frequent changing of the direction of rotation, such as, in particular, electrical parking barriers or toll road barriers. <IMAGE> |
