Time switches maximise energy saving through astrological programming
Finder has launched a pair of digital weekly time switches providing a programming capability enabling switching according to local sunrise and sunset times, that are automatically calculated from user input of current date, time and either local longitude and latitude or nearest major city.
AddiRespectively single and two channel models, with 16A 250VAC changeover outputs, the 12.91 and 12.92 timers will directly switch lamp loads up to 2kW. These highly flexible timers support up to 60 on/off output switching events, programmable to the nearest minute and impulse outputs programmable from 1 second through to 59 minutes 59 seconds.
Provided in a compact 35mm DIN rail mounted enclosure and featuring a ‘widescreen’ LCD display with intuitive programming interface, the two timers will suit a variety of consumer unit or control panel applications tasked with reducing the energy consumed by lighting, heating and ventilation equipment in commercial and municipal buildings.
