LED Dimmer 1W-150W MainsDIM Triac Trailing Edge

Phase-cut LED dimmer with soft-start functionality. Compact, safe and silent – suitable for up to 150W of dimmable LED lighting (230V). Designed for flush mounting in standard EU wall boxes. This dimmer is designed for flush-mounted applications and supports phase-cut dimming up to 150 watts. It operates on 220–240V AC mains power and uses screw terminals. Minimum installation depth is 24 mm. Suitable for indoor use only. The dimmer is compatible with most European switchgear brands such as Gira, Jung and Busch-Jaeger. The push-button with soft-start enables silent and comfortable operation. The integrated electronic protection temporarily disables the dimmer in case of overheating or short circuit. Unlike conventional fuses, there is no physical interruption of the circuit – the system automatically resets once the issue is resolved. Also suitable for two-way switching via a secondary push-button. The minimum dimming level can be manually adjusted via the built-in tuning screw – ideal for preventing flicker at low loads. Matching cover frames are optionally available in white and black.

Cause: Overtemperature protection has been triggered. Solution: Reduce the connected load and verify proper installation conditions to allow sufficient cooling. Issue: The dimmer briefly switches off and then turns back on. Cause: Short-circuit protection was activated, but the fault has cleared. Solution: No action required. The system automatically resumes operation once the fault is gone. Issue: The dimmer switches off and cannot be turned back on. Cause: A persistent short-circuit has triggered the safety mechanism. Solution: Eliminate the short-circuit. Then restore operation by pressing the control knob twice. Note: The short-circuit protection is electronic and not based on a conventional fuse. There is no mechanical separation of the power circuit. Technical specifications • Trailing-edge dimmer with soft-touch push-button operation • Short-circuit and over-temperature protection built-in • Compatible with most EU switch frames (e.g. Gira, Jung, Busch-Jaeger) • Adapter included for thicker dimmer knobs • Suitable for recessed downlights, surface fixtures, and LED retrofit lamps • Supports two-way switching with separate push button Note: Minor flickering may occur if minimum load is not met or due to grid pulses. This is normal behaviour.
