## Long description

The Harry Potter DIMMER ARMPMV 400 W ST150 is a wired lighting dimmer module designed to control and adjust the brightness of compatible lamps and lighting circuits up to 400 watts. Intended for installation in residential and small commercial environments, the module provides stepless dimming for suitable incandescent, halogen, and dimmable LED loads within its power rating. The compact in-line design fits into junction boxes or behind switches where space is limited and allows centralised or local control of illumination levels for functional and decorative lighting applications.
Advantages
This dimmer module offers precise brightness control and supports loads up to 400 W, enabling smooth transitions between light levels. Its wired configuration ensures stable, low-latency response and reliable operation in fixed installations. The device is compatible with common lamp types that support phase-cut dimming and can contribute to reduced energy use when lights are dimmed. Built for integration into existing electrical installations, the module simplifies retrofitting adjustable lighting without replacing fixtures.
Suitable for
Adjusting mood and ambient lighting in living rooms, bedrooms and dining areas
Dimmed task lighting in small offices and reception areas
Control of track lighting, spotlights and recessed luminaires within the 400 W limit
Retrofit installations where space is limited and a wired dimmer module is required
Key specifications
Maximum load power: 400 W
Mounting type: in-line / behind switch / junction box installation
Control type: wired phase-cut dimming suitable for compatible lamps
Supported lamp types: incandescent, halogen, dimmable LED (when compatible with phase-cut dimming)
Intended use: residential and small commercial lighting circuits
How to use
Install the dimmer module according to local electrical regulations and manufacturer wiring diagrams, placing it in a junction box or behind a wall switch as appropriate. Connect the live and neutral conductors and the load conductor to the module terminals, ensuring the total connected load does not exceed 400 W. After wiring, restore power and test dimming functionality with the intended lamps; some dimmable LED fixtures may require compatible drivers or a minimum load to operate smoothly. If necessary, adjust the connected control switch or trim settings following the installer instructions.
Usage recommendations
For reliable performance, use the module only with lamps and drivers specified as dimmable by phase-cut control, avoid exceeding the 400 W rating, and consult a qualified electrician for installation to ensure safe connection and compliance with local codes.
