Thor’s DRM750 & 1050 Ripple Filters: AC Mains Filtered Protection
Thor’s Ripple Filters. Reduce or cancel the effects of the 750Hz or 1050Hz ripple frequency.
Understanding Ripple Control Signals
Ripple control signals are low-level voltages injected into the power grid at specific frequencies to manage off-peak appliances, commonly for hot water and heating systems. Power utilities typically use a unique frequency for each suburb (e.g., 1050Hz or 750Hz). Thor’s DRM1050 and DRM750 Ripple Filters are designed to mitigate the effects of these signals, ensuring your electrical systems operate smoothly.
Impact of Ripple Control Signals
Ripple control signals can cause issues that directly affect your experience:
- LED flickering can become a distracting nuisance.
- Dimmer control issues can prevent you from setting the perfect lighting ambiance.
- Fan motor noise can disrupt the peace in your home.
- Motor noise, in general, can be an unwelcome addition to your environment.
- Random on/off switching of electrical equipment can be both inconvenient and concerning.
The Role of Thor’s DRM1050 and DRM750 Ripple Filters
Thor’s DRM1050 and DRM750 are DIN Rail Mountable, 10A 230/240V filters engineered to reduce or eliminate the effects of 1050Hz and 750Hz ripple frequencies, respectively. These filters are designed to seamlessly integrate into your existing electrical setup.
When used with phase-cut dimmer modules, Thor’s Ripple filters can improve your dimming range, cold start values, dimming curves, and overall performance consistency, enhancing the reliability of your LED lighting. You’ll notice a significant improvement in how your lights perform.
Each installation site presents its own unique characteristics. Factors such as distance from substations, voltage levels, load, and connected electrical equipment can influence the effectiveness of mains signalling mitigation. Results may vary, with some sites experiencing complete elimination while others see only partial improvement. This variability is due to the complex interaction of contributing factors, not a fault of the filter itself. Your specific situation will determine the extent of the improvement.
Ripple signals, once limited to specific times, are now used more broadly for load shedding, street lighting control, air conditioning, and other equipment management to meet modern standards. Signalling is now more frequent and can occur at any time, so you may be experiencing these effects more often than you realise.

Did You Know?
Assessing Ripple Filter Ineffectiveness:
(If minimal improvement is observed after installation)
- Incompatible LED Lights and Dimmers: Flickering can arise from product incompatibility, not ripple injection. The Ripple Filter will not resolve this issue.
- Number of Lighting Circuits: Each lighting circuit requires its own Ripple Filter to function optimally.
- Unique site challenges: Each site presents unique challenges, and your situation is no different. Resolution outcomes can vary significantly.
A DRM95 20A filter might mitigate noise across various frequencies, offering a broader solution.
