The Kato 305 Syncro3 version based on communication between actuators through a direct connection allows instantaneous control of the force, speed and resistance of each actuator through an encoder reading of the work of the individual motors. The continuous exchange of information allows the actuators to open and close in synchronization. Syncro3 is the evolution of the first patent that provided for installation and wiring of a maximum of two motors connected directly to one another. Today the Syncro3 software allows connection of up to 8 motors directly to one another without the need for external synchronization control units. The number of actuators to be included on the frame in Syncro3 function varies according to the dimensions, weight and type of the frame itself. For a width of more than 1200 mm the use of two motors is already recommended in order to allow correct movement and perimeter seal of the frame when closed. An additional actuator is recommended for every additional 1200 mm of width.

KATO 305 RWA 24V SYNCRO3 – Specifications

Electric linear actuator with double-row four-link articulated chain enclosed in an appropriate composite casing, suited for moving awning windows, hopper windows, dormer windows and light domes. The actuator has a push and pull force of 250N and is designed to function at 110/230V AC 50/60Hz or 24V DC. It is supplied complete with quick coupling screw-less assembly brackets (patented). Awning or hopper window brackets with quick coupling (patented). Two opening strokes with mechanical selection. Stroke-end stop during opening and closing at power absorption and as protection against overloading. Can be connected in parallel.

Complies with the Directives 2004/108 EC (EMC Directive) and 2006/95 EC (Low Voltage Directive).
