750Hz Ripple Signal Filter

Product Description

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.

Our HNS030RF 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.

With models available for 750Hz and 1050Hz frequency, we can supply an option to suit most affected areas.

Selecting a Ripple Signal Filter Frequency

The HNS030RF-750 ripple signal filter is tuned to eliminate ripple control signal frequency of 750Hz.

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. Other regions of New South Wales, such as Newcastle, Dee Why and the Central Coast area, inject a 1050Hz ripple control signal frequency and will require a suitable filter model, see our part number HNS030RF-1050.

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.

Note: Our Ripple Signal Filters are not suitable for areas that use a ripple control signal of 492Hz, such as St George and some areas of Muswellbrook.
