Learn more by watching our Cabac HNS030RF-1050 | 1050Hz Ripple Signal Filter video.
The Cabac HNS030RF-1050 is a tuned passive ripple signal filter designed to eliminate 1050Hz off-peak ripple control signals injected into the electrical grid by electricity suppliers. The HNS030RF-1050 is rated for 250W maximum load on a single circuit, operates on standard 230V–240V mains supply, and complies with AS/NZS 3100. This filter protects sensitive appliances and lighting from the effects of ripple injection control systems, stopping flickering LED lights and buzzing fans during ripple signal events.
In Southern Queensland (Energex area), electricity suppliers inject a 1050Hz ripple control signal onto the distribution network to remotely control devices such as off-peak hot water systems and street lighting. While this system allows customers access to cheaper off-peak electricity rates, the ripple signal can disrupt sensitive electrical appliances. Fans may produce audible buzzing, LED lights may flicker, and lighting control systems can become erratic whenever ripple signals are present. The HNS030RF-1050 is a tuned passive inline filter that completely eliminates the ripple signal from the mains supply, producing a noise-free filtered output that can then be connected to lighting circuits or appliance loads.
Sparkies installing LED downlights, dimmer switches, or fan controllers in ripple control areas often encounter flicker complaints after commissioning. The HNS030RF-1050 is a straightforward retrofit solution that can be installed at the circuit breaker or inline before the load, with no rewiring of existing circuits required. Licensed electricians value this filter for reliability on new builds and renovations in ripple-controlled zones, where it eliminates the need for repeat site visits to troubleshoot lighting issues.
The Cabac HNS030RF-1050 is not suitable for outdoor or damp exposed locations. Do not install this filter in wet areas, bathrooms, laundries, or any location where moisture or condensation may be present. The IP20 rating is for dry interior use only. Additionally, the HNS030RF-1050 is not effective for ripple control frequencies outside 1050Hz; check with your electricity supplier to confirm the ripple signal frequency in your area before purchasing.
(HNS030RF-1050)
Ripple control signals are coded radio signals injected onto the electrical mains by electricity suppliers to remotely control devices like hot water systems, turning them on or off during off-peak periods. Southern Queensland (Energex) uses a 1050Hz ripple signal. While this system saves customers money on off-peak electricity, the signal can disrupt sensitive appliances, causing LED lights to flicker and fans to buzz whenever the signal is active.
Only Southern Queensland (Energex area) uses the 1050Hz ripple control signal. The rest of Queensland (Ergon) does not have ripple signalling. If you are in Energex territory and experience LED flicker or fan buzzing during certain times of day (typically during off-peak periods), your area likely has ripple control active. Contact Energex directly or check your electricity supplier's documentation to confirm.
Installation of the HNS030RF-1050 must be carried out by a licensed electrical contractor or similarly qualified person as part of a fixed-wire electrical installation. This is a legal requirement under Australian electrical safety standards. The filter must be properly integrated with your circuit breaker and connected to the mains supply.
The filter is installed as an inline unit between the circuit breaker and the load (lights or dimmers). It connects using standard two-core-and-earth cable and sits between the MCB protecting the circuit and the lighting loads. For dimmer circuits, the filter sits before the dimmer switch, allowing the filtered mains to feed the control system. Your licensed electrician will determine the best placement based on your circuit layout.
Yes, the HNS030RF-1050 is fully compatible with LED downlights and dimmer switches, including S-Click dimmers. The filter eliminates ripple signals and allows LED lights and dimmers to operate normally without flicker during ripple events. When installed before a dimmer, the filter provides a clean, ripple-free mains supply to the dimmer control system, ensuring smooth dimming operation.
The 250W rating refers to the maximum total load that can be connected to a single HNS030RF-1050 unit on one circuit protected by a 10A circuit breaker. This covers most residential lighting circuits and dimmer systems. If you have multiple lighting circuits or loads exceeding 250W, you will need one filter per circuit. Your electrician can assess your installation and advise on the number of units required.
