TRIAC Dimming vs 0/1-10V Dimming
Joalo ka TRIAC, sistimi ea 0-10V ke mokhoa oa ho fifatsa oa analog. Mokhanni ho eona o na le likou tse peli tse eketsehileng bakeng sa +10V le -10V. Leha ho le joalo, dimmer ea setso ea Triac e na le kou e le 'ngoe feela ea +10v le -10v.
Sesebelisoa sa dimming sa 0/1-10V se laola mats'oao a motlakase o bobebe lipakeng tsa zero le li-volts tse leshome (bakeng sa ho jella 0-10V) le ho tloha ho volts e le 'ngoe ho isa ho tse leshome (bakeng sa ho jella 1-10V). Tabeng ena, 0V e fella ka ho tima ka ho feletseng, 'me 10V ke boemo bo phahameng ka ho fetisisa ba ho khanya. Ka 1-10V dimming, tlhahiso ea hona joale ke 10% ha motlakase o le 1V, 'me ke 100% ha motlakase o le 10V. Ho fapana le 0-10V, e nang le sesebelisoa sa ho tima / ho tima, 1-10V ha e na eona. Ka hona, u ke ke ua tima leseli ka botlalo ka 1-10V dimming, empa u ka e etsa ka eona 0-10V nyamela.
