Wireless Control System for Street and Area Lighting

Dimming street lights during off-peak times can save up to 30% in energy. Utilities need a reliable method

of metering a city’s street lights in order to credit the city for their energy savings. Owlet’s on-board

Metering Chipset monitors and reports power usage within a ±2% accuracy which is acceptable to most

utilities, so why invest in controls if your utility does not accept the metering!

Owlet is Schréder’s telemanagement system for monitoring, controlling, metering and managing

outdoor lighting. Based on open technologies it saves energy, reduces greenhouse gas emissions,

improves outdoor lighting reliability and lowers maintenance costs. Owlet is ideal for street and roadway

lighting, college and corporate campuses, city centers, parking lots, boardwalks and other area lighting

applications.

Our controls work with any lighting manufacturer’s luminaires and we partner with all LED luminaire

manufacturers on projects.

Each individual luminaire can be switched on or off and dimmed at any time. The luminaire’s operating

state, energy consumption and component malfunctions are reported and stored in a database, noting

the time and geographical location. Owlet incorporates open architecture technology, with modern web

based applications for a system that can be upgraded and interfaced with other systems as technologies

evolve in the future.

Energy Saving Strategies

Reduce your energy consumption for lighting by an average of 40%

• TIME BASED SAVINGSSave an average of 40 percent of

energy costs by adjusting the

lighting levels to the time

and local conditions. For

example, lower levels

late at night and higher

levels when pedestrians

are present.

All controlled luminaires are monitored

so alerts can be sent for outages or other

equipment problems. Adjustments can

be made remotely to on/off schedules

or light levels.

All field information is stored in a

database for energy analysis, lamp life

forecasting and other evaluation.

• VIRTUAL POWER OUTPUTDetermine the exact wattage

required for the lumen output

required instead of having

to choose a higher wattage

lamp for minimum light level

requirements.

• CONSTANT LIGHT OUTPUTSave up to 10 percent of

energy costs by reducing the

power and lumen output for

new lamps that deliver more light

compared to older lamps nearing the

end of their life cycle.

Luminaire Controller

The luminaire controller is a small, compact design that can be

installed in the light fixture housing. Current, voltage and power

factor are continuously monitored and logged. A built-in backup

astronomical clock provides switching after sunset and before

sunrise, even when disconnected from the rest of the system.

Pole Mounted Luminaire Controller

This controller contains two independent controllers with one

dimming output for both luminaires (loads), each individually

energy metered and ideal if more than one load is attached to

a pole, such as double brackets, festive lighting, advertising

signs, etc. The energy consumption of each output is individually

metered through Class 1 meters on board. Current, voltage and

power factor are also continuously monitored.

Segment Controller

A segment controller manages up to 150 luminaire controllers.

It collects the data through a ZigBee® self healing mesh network

and then transmits the data over the internet to the Owlet web

server. Data is securely exchanged through a VPN connection. The

controller can also acquire data from the meter for monitoring

energy usage billing purposes.
