- Model 440 Microstack™

The Model 440 MICROSTACK features multi-color and multiformat optical signalling using strobes and/or steady burning or flashing NEOBE lamps in any combination. NEOBE lamps are gas discharge lamps which have no filament to wear or break. All MICROSTACK modules operate over a worldwide AC input voltage range of 85-264 VAC 50/60 Hz. They all use the same type of lamp and maintain a constant brightness and flash rate over the entire range. MICROSTACK modules separate at any level by removing two screws. All MICROSTACK modules are sealed with O-rings against dust and can be used outdoors.


The Microstack can be ordered as a preassembled unit or as components or modules.
