No ondarakel tan ondarakel so produkto na saray kustomer, saray contactor, ya matukoy ed panangontrol na atagey a kuryente, so uusaren bilang load switching devices parad nanduruman kagawaan ed kuryente ya mankaukolan na atagey a kuryente tan atagey a boltahe.
Balet, lapud ondarakel so mankaukolan na melag, anlemew, tan mas manipis iran kagawaan, say uso na pangisaliwan ed angkakabaleg iran contactor na angkekelag, atagey-kapasidad ya printed circuit board (PCB) relay ya sarag ton amperen so atagey a kuryente tan atagey a boltahe et talagan ondarakel.
Niarum ni, wala ray kustomer, ya maniilalo ed idakel na pankaukolan ed arapen tan idakel na produksyon, ya manguusar na PCB relays pian nabawasan so gastos diad pangitipon na saray load switching device ed printed circuit board, bilang sakey a paraan pian nabawasan so panaon na produksyon.
Say sankairapan ya problema ed kanonotan ya kaukolan ya talonaan ed pangisaliwan na saray contactor na PCB relay et say baleg ya pananguman ed desinyo ya kaukolan pian nasalatan so tradisyonal ya kable na kable na "board-based" ya kable.
Say PCB relay et sakey ya electronic control device ya inyan ed sakey ya printed circuit board. No ikombina so relay tan say circuit board, nagamoran so compact tan intuitive ya layout na circuit. Say manunan gagala to et say pangontrol ed atagey ya kuryente ed abeban kuryente, kanian matukoy itan parad automatikon panag-adjust, proteksion ed kaligenan, tan saray aplikasyon na panag-switch na circuit.
