Ripple control signals are in NSW and Queensland & New Zealand — but do you know how they affect your electronics? Power utilities inject low-level ripple control signals into the distribution network to switch hot water systems, control air conditioners, manage streetlights, and shed load. But those same signals can wreak havoc on sensitive electronics. ⚡ Common effects of ripple signals: LED lighting that pulses, brightens, or dims erratically Ceiling fans and motors becoming noisy Electronics randomly turning on or off Reduced LED lifespan and performance That’s where Thor’s DRM Ripple Filters come in. ✅ DRM 1050 targets 1050 Hz ripple signals ✅ DRM 750 targets 750 Hz ripple signals ✅ DIN rail mount, 10A, 230/240V design ✅ Improve dimming curves, cold-start values, and LED reliability When combined with Thor’s surge and active filtration models (DRM 9520A / DRM 9530A), they deliver the most complete solution available for ripple noise and unwanted interference.
