Alpha 550 230V and Alpha 550 24V are models of the Alpha series electric gate openers. The Alpha series electric gate openers feature a mechanical locking system that locks the operator in the open and closed positions, eliminating the need for electric locks and/or magnetic locks. The torque intensity and anti-crushing safety of this electric gate opener can be adjusted through the control board. The Alpha Plus model also features mechanical limit switches that are located and protected in an aluminum housing. This electric gate opener also features a key-locked manual release lever that should only be used in case of an emergency and/or power failure to manually operate the gate.
