High use intensity is ensured by the built-in switching power supply (100/250 Vac) which allows for a lower consumption and a longer useful life of the operator itself. Maximum safety is guaranteed by the STC system unit which enables precise calculation of torque in each stage of gate movement. A virtual encoder optimizes the power output and prevents false relay tripping. All metal release system with personalized key. Fitted with the SIS accessory, the unit also features a rapid serial connection to enable operation of twin-leaf sliding gates. A built-in battery charger ensures that the unit will continue to operate in the event of a power supply failure. Quick and easy to install thanks to the self-programming of the control unit from the transmitter. The function can be activated at the first installation.
