The Miracle-Two is the first linear mechanical, 24-volt DC gate operators that offers all the features the consumer demands. One of these features is variable speed, which is electronically controlled by a micro controller and precise limit switch system. The gate operator starts the cycle slowly, increases in speed, and then comes to a stop slowly with the use of internal limit switches. This reduces stress and creates consistently smooth opeartion. Battery backup is included to provide fully functional operation for 100-200 cycles in case of power failure. Built-in 315 MHz receiver included. Power transformer required to power unit included. Included is a 2-way reversing sensor and a vandalism/burglar alarm indicator. The state of the art features offered in the Miracle-Two make it one of the most advanced operators in the world and will create new standards in the gate operator industry.(A $65.00 handling fee will be added to the price of the item)**** Note: Shipping costs may vary according to the respected shipping weight, destination, cost of items and insurance of the package.
