Powersoft has patented a new technology that incorporates solar power with bi-directional wireless A/V communications.
The first product to show the potential of this concept is the DEVA 1S, which consists of a power/control module and an interface module. The power/control module is made up of a solar panel and batteries, as well as processing, WiFi communication and amplification. The interface module consists of loudspeakers, light, and optional devices such as camera, microphone and telemetric sensors.
“The DEVA technology has endless possibilities,” explained Thomas Mittelmann, Powersoft business development manager. “Theme parks, sport venues, corporate and public facilities, transport hubs, emergency/rescue services, even shopping centres – they all difficulties distributing sound and surveillance over large areas because of the infrastructure it demands. DEVA is a self-contained, completely independent concept providing everything needed and it is wireless. It can be easily tailored to the exact requirements of an application and can be installed very easily."
"Powersoft has always prided itself on its extremely efficient amplifier technology," added Claudio Lastrucci, Powersoft managing director and head of R&D. "Efficiency was also the key when designing DEVA. Solar power is 'green' and freely available, but to keep a product compact, you must reduce the power consumption of everything running off it. The DEVA 1S is a fairly small device and capable of running longer than necessary even in complete darkness.”
Lastrucci continues, “The same is true for the video or surveillance features of the unit. The DEVA unit(s) is configured according to the customer's specifications, connects via WiFi to standard equipment, and does not cost anything more once installed."
The high-capacity battery, which is charged through the solar panel even in low light conditions, offers around. 30 days of stand-by. The integration of a Class D amplifier into the unit helps support up to 40 hours of continuous audio playback equivalent to 5 days at 8 hours/day. An energy-efficient high-powered white LED supplies optical signalling or lighting as video image support for up to 5 hours.
Due to its dimensions, the DEVA 1S can be installed permanently or temporarily. It can be mounted to walls or poles, allowing the power/control panel to be aimed at the sun and the interface module at the audience. Weather resistant moulded plastic enclosures are available in custom colours to match specific applications.
