Weatherproof Motorized
Blackout Shutter

The new Phoebus Weatherproof Motorized Blackout Shutter is designed to provide full blackout for 1000 watt metal halide or xenon exterior luminaries or other similar fixtures.

The WMBS-20 shutter can be remotely controlled via either analog or DMX-512 control. The system operates on either 120, 220 or 277 volt AC input controlling the shutters via a 24 volt DC two wire control/power signal.

The WMBS-20 shutter can be combined with a color scroller and mounted to a variety of lighting fixtures.

The responsive smooth, chatterless 2 second movement of the shutter enables an operator to create and remotely control lighting effects for theatre, sports events, rock concerts and motion picture production.

Phoebus has the ability to build custom units to interface with a wide variety of fixture sizes, shapes and applications.
