Kusankha mtundu woyenera wa ma voltage regulator kumatha kupangitsa kuti izikhala ndi gawo lalikulu. Zotsatirazi ndi zina mwa magawo ake ogwiritsira ntchito. Mitundu yogwiritsira ntchito magetsi a magawo atatu ndi yotakata, ndipo imagawidwa m'madera akuluakulu monga mayendedwe, positi ndi matelefoni, wailesi ndi wailesi yakanema, ndi makompyuta.
Kuphatikiza apo, m'magawo ena omwe amafunikira kulondola kwapang'onopang'ono kwa data, monga makina opangira jakisoni wamakompyuta, zida zamakina a CNC, ma mota osiyanasiyana amagetsi ndi zida zina, komanso zida zachipatala zomwe zimatumizidwa kunja (monga makina a CT) ndi ma elevator osiyanasiyana omwe amathandizira zitsanzo zapadera, Komanso Itha kugwiritsidwa ntchito, ndipo gawo lake limathandizira kupanga kwa anthu.

M'malo mwake, mawonekedwe ake ogwiritsira ntchito ndi otakata kwambiri poyerekeza ndi mitundu ina yamagetsi owongolera. Pamene njira zopangira zikuyenda bwino, akukhulupirira kuti zidzakhala ndi ntchito zambiri.
Single-gawo voltage stabilizer nthawi zambiri imatanthawuza kulowetsa ndi kutulutsa kwa 220V ku China, ndipo mizere yolowera ndi yotulutsa ndi mzere wosalowerera ndale ndi mzere wamoyo, kenako mzere wapansi umawonjezeredwa, ndipo mizere itatuyi imagwiritsidwa ntchito magawo olowetsa ndi kutulutsa.
Zowongolera magetsi zagawo limodzi nthawi zambiri zimagwiritsidwa ntchito pazida zotsika mphamvu monga zida zapakhomo, zida zamaofesi, ndi zida zazing'ono zoyesera.


Magawo atatu owongolera ma voltage nthawi zambiri amadziwika bwino ndi ogwiritsa ntchito madera. Atatu gawo mphamvu zambiri amatanthauza mphamvu mafakitale 380V. Mawaya ake olowera ndi otulutsa nthawi zambiri amalumikizidwa ndi mawaya atatu amoyo. Njira yopangira mawaya ndi atatu-gawo atatu waya, atatu-gawo anayi waya, atatu-gawo asanu waya, etc.
Kusiyanitsa pakati pa ziwirizi ndikuti kulowetsa ndi kutulutsa ma voltages ndi kuchuluka kwa mizere yofikira ndizosiyana, komanso mawonekedwe amkati ndi kagwiritsidwe ntchito ndizosiyana. Pogwiritsidwa ntchito, owongolera magetsi a gawo limodzi amangogwiritsidwa ntchito pamagetsi amodzi, pomwe owongolera magetsi amatha kukhala magawo atatu. Malinga ndi zofunikira zapadera za fakitale pakupanga, itha kugwiritsidwanso ntchito pagawo limodzi lamagetsi.
