• "Safety turbine" is a single injection moulding of 6 aerofoil blades protected by an outer ring.
• Trickle charges in windspeeds as low as 5 Knots
• Produces 25w in 19 Knots
• Produces up to 60w, nominally 5A @ 12V in 50 Knots
• Stainless steel fasteners and marine grade materials
• Turbine diameter of 500mm
• Compact turning radius of just 225mm, great for when space is at a premium
• Latest design improvements - the Rutland 503 is more reliable and efficient than ever!
• No radiated interference - complies fully with BS EN5008-1 1992

Balance of System Components:

• SR60 - Shunt type voltage regulator prevents battery overcharge.
• RWS60 Controller - incorporates SR60 in attractively housed controller including ammeter, LED voltage level indicator, charge fuse and simple to wire terminals. Input terminals included for solar panel of maximum 30w
• Marine Mounting Kit supplied in 2 sections of stainless steel tube plus deck fixing and fasteners.

Other System Components:

• Batteries - We recommend deep cycle lead acid batteries, sealed or non-sealed of a minimum capacity of 50AH @ 12V
• Cable - Cable thickness depends on the overall length used between the wind generator, regulator and battery. For distances up to 20m a cable thickness of 2.5mm is recommended. The regulator should always be sited within 1.5m of the battery to minimise voltage losses and ensure accuracy of battery regulation.
• Mounting pole for land based systems - the 503 can be installed on land using Marlec's 1m section of tube. This can be adapted to fit onto a 6m length of 61mm diameter tube available through a local tube stockholder.
• Mounting pole for on-board systems - you can make your own mounting pole using a 31.7mm (1.25") internal diameter tube, the maximum external diameter should be 38mm (1.5").
