Electricity suppliers for certain geographical areas of New South Wales and Queensland inject an off-peak ripple control signal onto their distribution networks in order to remotely control devices such as hot water systems. This allows for access to cheaper off-peak electricity, but can have an unfortunate effect on electrical appliances that are sensitive to the superimposed control signal.

The Cabac ripple signal filter is a simple and easy-to-install solution to this problem, preventing the unwelcome effects of ripple signal events such as flickering LED lights or loud, buzzing fans. The ripple signal filter is a tuned passive inline filter which eliminates the superimposed ripple injection control signal from the normal mains supply to create a noise free filtered mains supply which can then be connected to the electrical appliances or light control systems. The device is designed to fit through a downlight hole and is compatible with LED, Halogen, CFL and Incandescent lamps.

Use the HNS030RF-750 for areas of New South Wales that inject a 750Hz off-peak ripple control signal, such as Maitland, Bankstown, Sutherland, Sydney main load area and parts of Muswellbrook. 

If in doubt about the ripple control signal for a particular location, always check with the service provider for confirmation before selecting a filter device. The HNS030RF is to be installed as part of a fixed wire electrical installation. By law such installations must be made by an electrical contractor or similarly qualified person.
