ACT jerin dijital zazzabi mai watsawa ne mu kamfanin da kansa ci gaba da samar da high daidaito mai hankali zazzabi ma'auni kayan aiki. Wannan mai watsawa ya ƙunshi firikwensin zafin jiki, kewayon sarrafa sigina da kewayon fitarwa. Kayan aikin siginar ya ƙunshi sabbin masu sarrafawa masu ƙarancin ƙarfi da guntu masu sarrafa siginar da guntu masu sarrafa wutar lantarki. Kayan aikin yana da kyakkyawan bayyanar, ƙarami da kyau, yana da sauƙin amfani da aiki.
