Answer:
The FAAC C851 delivers an adjustable opening speed of 20 to 40 m/min (up to 0.7 m/s) with a 100% continuous duty rating. High throughput is driven by a 1.1 kW three-phase motor managed by an integrated E850S frequency inverter, an electric brake for irreversible mechanical locking, and a 1.5 mm zinc-primed, powder-coated steel protective cover.
Engineered specifically for high-security facilities requiring rapid perimeter closure—such as warehouses, logistics terminals, embassies, prisons, and commercial distribution centers—the FAAC C851 provides adjustable leaf travel speeds between 20 and 40 meters per minute (up to 0.7 m/s).
Key differentiators that enable this performance include:
- Integrated E850S Inverter Board: Features an onboard frequency inverter that manages opening and closing acceleration and deceleration ramps independently. The panel includes dedicated setup buttons, a digital programming display, and dual protective covers (dark and transparent) for clean maintenance access.
- Shaft-Mounted Electric Brake: Ensures immediate, positive stopping and mechanical irreversibility when the gate reaches its end-of-run or stops mid-cycle, resisting external forcing without mechanical back-driving.
- Continuous Duty Thermal Management: Rated at 100% duty cycle at 25°C ambient temperature with thermal cutout calibrated to 75°C.
- Robust Enclosure & Chassis: The internal mechanics are protected by a heavy-gauge 1.5 mm steel outer housing treated with a protective zinc primer and powder-coated paint finish, supplemented by an external-access manual release that permits manual gate movement during power interruptions without removing the cover.
