Any alarms and their exact location are shown on the map for easy and fast overview.
CO 2 reductions Reducing the costs and CO 2 emissions of streetlights is a necessary challenge for most utilities and distribution companies who face: Rapidly increasing electricity costs CO 2 reduction requirements Growing electricity demands Commitment to the Kyoto protocol Worldwide customer base We know that reliability, stability and consistency are key elements of a well-functioning streetlight system, and AmpLight is a well-proven and extremely dependable solution with installations worldwide. We offer the most advanced and flexible solution on the market recognized by the largest customer base. Fifty percent of all Danish streetlights are controlled with AmpLight, and our solution is installed all over Scandinavia, in Eastern and Southern Europe, the Middle East and Asia. In short, we control millions of streetlights for hundreds of large enterprises and road lighting customers. Solution types Simple control Many of our clients request a centralized solution that provides on/off control for burn hour optimization, simplified maintenance and a remotely operated system. The typical gain is an installation that is easy to operate and maintain and energy savings of 8-10%, even without dimming. Clients with this solution include Copenhagen municipality, Gothenburg and the national road authorities of Sweden and Norway. Dimming For clients who focus on energy savings, we recommend our dimming solution. These clients often have roads with much differentiated traffic patterns where it makes good sense to dim during off-peak traffic hours. Centralized dimming provides savings of up to 35% and is installed for e.g. the national Danish road authorities as well as in Beijing and Istanbul municipalities. Monitoring A number of our clients request full monitoring capabilities of their streetlight installation, and demand a very high up-time. With AmpLight they get full knowledge of faults in the control cabinet and gain a system with optimized maintenance and service functionalities. Clients with this solution include the national Danish road authorities. AmpLight control room installed in the Middle East.
AmpLight - Full Solution Overview For AmpLight roll-out, hardware modules are installed in the control cabinets and enable communication from the central server location to the control cabinets via wireless (e.g. GPRS) or wired (e.g. fiber optical) communication. With AmpLight' building block system, AmpLight, the solution can be tailor-made for each client and is easily upgraded by adding new modules with additional functionalities. Start with simple on/off functionalities and add more as needed. The highly flexible solution enables clients to choose from different configurations depending on their requirements. The figure below shows the four different options of an AmpLight solution. These options can be mixed and matched as needed, letting a municipality be partly equipped with the basic solution, and still have dimming in other parts of town. AmpLight Basic Photocell AmpWeb Servers 1 Control Room GSM GPRS AmpLight Dimming 2 WiFi Cellphone WiMax AmpLight Monitoring 3 Computer Billing / GIS / Scada
Configurations AmpLight Basic This configuration provides basic on/off functionalities via the CPU and a switch module. The CPU runs on Linux and communicates with the server via wired or wireless technologies. The CPU is remotely updated with new configurations and software and uses multiple communication carriers to provide stabile and reliable communication. With optimizing the on/off settings of the streetlights, it results in savings of 8-10%. AmpLight Dimming Adding a dimming module allows the client to decrease the light level and thereby reduce electricity consumption. The light is dimmed from the control cabinet, allowing the client to make individual dimming settings for each sector of the city. To combine with Philips dimmable driver or step-dim ballast, dimming will typically provide up to 35% energy savings. AmpLight Monitoring 1 2 3 With an additional module, the control cabinet is fully monitored and will immediately report power failures or cable breakages to the central server or via SMS to the supervisor. Infrastructure AmpLight is fully scalable and is installed in the existing equipment without requiring new cabling. Open source software facilitates easy integration with the clients' SCADA, Call Center and GIS applications. The communication is based on both wired and wireless carriers such as: GPRS/GSM SMS WiFi WiMax Fiber optics Ethernet New communication technologies are rapidly embedded into the solution via remote updates of the modules. All data is sent to the central server, where it is stored and accessible for reports, fault rectification, load balancing and emergency responses in case of accidents, flooding or similar.
Cabinet Fault Detection An AmpLight Monitoring solution enables the client to fully monitor all faults and critical conditions in the control cabinet. When a fault is detected, an alarm is immediately sent to the web platform, where all faults are monitored and reported real-time. If necessary, the alarm can be distributed to relevant people via email or SMS. 10 8 F A. AmpLight CPU B. AmpLight Battery C. AmpLight Switch D. AmpLight Current E. Power meter F. Manual switch G.

Bulb failures Any fault states will be displayed on the user interface which also provides an easy way of configuring the system to the client's requirements. Unique carrier switching ensures that all data, including alarms, are sent via the best available method. Multiple carrier technologies are used as backup for each other in order to ensure system availability. The system will classify the data and select the best communication method according to the importance of the information. This way, SMS technology can be used as fallback in case e.g. the GPRS network is unavailable.
AmpLight Module System An installation based on the AmpLight Module System (AmpLight) consists of a number of components working seamlessly together to achieve the desired functionality. This modular flexibility makes the system scalable in the future and allows for easy expansion of functionalities if necessary. When new components are installed, they are automatically discovered and will establish communication with the rest of the system, and a host of new functionalities will be ready for configuration in the server. All AmpLight modules incorporate an A-bus interface for direct communication between modules. This interface is also used for power supply to modules which are not self-powered, or for powering the system from batteries during power outages. A-bus All AmpLight modules communicate directly via an A-bus interface. This interface is also used for power supply to modules which are not self-powered, or for powering the system from batteries during power outages. The modules can withstand extreme temperatures from -40 C to +60 C and are installed and thoroughly tested in climates around the world, from cold, humid areas in Norway to dry desert environments of the Gulf region. The A-bus provides direct communication between the modules.
Module overview, AmpLight AmpLight CPU is the core module in the AmpLight series. The CPU runs on Linux and has built-in Flash Memory for persistent storage.the module also features internal health monitoring and logging, and monitors phase voltage on all three phases to the control cabinet. The AmpLight CPU autonomously executes complex tasks based on the configurations set up by the user. Data are either stored locally until scheduled delivery or delivered immediately, depending on the nature of the information. AmpLight Current is added for monitoring purposes.the module enables current detection in the control cabinet and has a built-in leakage detector. In conjunction with leakage and phase sensors, the unit can detect broken phases, segments, contactors, breakers, etc. AmpLight Switch has two built-in relays, 3A and 10A. It forms the basic AmpLight installation in conjunction with an AmpLight CPU, where it enables on/off functionalities of the streetlight. AmpLight Switch is also used to control dimming equipment. AmpLight Battery is the power supply for the A-bus, ensuring communication to the central server in case of a power outage.
