The MWS5 series of miniature microwave presence detectors provide automatic control of lighting loads with optional manual control. As microwave radiation penetrates plastic and glass, this unit has been specifically designed to be mounted inside a luminaire. They are sensitive to movement and are ideal for large spaces that have an awkward shape.

Three models are available:

Premium, direct dim, and analogue dim all of which will switch incandescent, fluorescent and compact fluorescent lighting. The direct dim variant controls DALI or DSI digital dimming ballasts whilst the analogue dim variant controls 1-10V dimming ballasts. The unit detects movement using a microwave sensor and turns the load on. When an area is no longer occupied the load will switch off after an adjustable time out period.

Two power supplies are available:

Standard power supply:This power supply has a 6A relay. It also has connections for an external switch that can be used to turn on the load when absence detection mode has been set or raised / lowered with dimming variants.

Slim-line power supply: Where space is at a premium the slim-line power supply is compact and suitable for luminaire mounting where a 2A relay is sufficient. This power supply does not have connections for external switches.

A selection of fixing clips to allow the unit to be mounted in, or to the side of a luminaire are available.

Functionality is fully programmable using either the UHS5 or UNLCDHS
