Powersoft announces solar power breakthrough

Powersoft announces solar power breakthrough

The company has patented a new technology incorporating solar power with bi-directional wireless AV communications, and announced the launch of the first related product.

The product in question, the weather-resistant DEVA 1S, consists of a power/control module and an interface module. The power/control module includes a solar panel, batteries, processing, WiFi communication and amplification. The interface module features loudspeakers, light, and optional devices such as camera, microphone and telemetric sensors.

Suitable for permanent or temporary installation, the DEVA 1S includes a high-capacity battery that is charged through the solar panel even in low light conditions, and offers approximately 30 days of stand-by. The integration of an ultra-efficient Class D amplifier into the unit helps support up to 40 hours of continuous audio playback, equivalent to five days at eight hours/day. Meanwhile, an energy-efficient high-powered white LED supplies optical signalling or lighting as video image support for up to five hours.

WiFi communication is utilised for set-up, upload and bi-directional real-time operation, as well as real-time feeds for music or announcements. Playback of locally stored audio is supplied via an internal SD memory card. Remote PC software aids in highly customised set-up and operation, including grouping of DEVA units in zones where required.

Ideal applications for the DEVA 1S include state/national parks, outdoor sporting events, amusement parks, transportation hubs and construction sites.

“The DEVA technology has endless possibilities,” said 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.”

Claudio Lastrucci, Powersoft MD and head of R&D, added: “Powersoft has always prided itself on its extremely efficient amplifier technology. 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.

“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.”
