Isilawuli samandla sochungechunge lwe-TPH sisetshenziswe ngempumelelo kusistimu yokushisisa kagesi embonini yensimbi nensimbi.Isistimu yokushisa kagesi inikwe amandla yikhabhinethi yokusabalalisa i-low-voltage.Amandla kagesi angu-380V angena kusilawuli samandla nge-breaker circuit kanye nefuse esheshayo.Isilawuli samandla sikhipha amandla ku-heater esithandweni sokushisa.Njengeyunithi yokulawula amandla yesistimu yokushisisa kagesi, isilawuli samandla singakwazi ukulawula ngempumelelo nangokunembile amandla kagesi aphumayo.Ngesikhathi esifanayo, ithola isignali kusuka kusistimu yekhompiyutha ephezulu ukuze ibone izinga lokushisa elivaliwe lokulawula iluphu.Inezici zokunemba kokulawula okuphezulu, umphumela omuhle wokulawula izinga lokushisa kanye nokuningi kokuxhumana okuzungezile.
