| Uimhir Módel | DNRH8 Comhdáilte Switch i Sísteam Stórála Fuinnimh |
| Voltáil réamhsraithe | DC 1500V |
| Cúr amach ar a dtugtar an-réiteach | 630A |
| Sraith | DNRH8 |
Is é an DNRH8 Combined Switch ná réiteach aon-chorpach ar son scuabadh carraigeacha DC agus díolaim, cuireadh ráta air go dtí 1500 VDC agus 630 A. Tá sé deartha chun catagóirí úsáide DC-PV1, DC-PV2, agus DC-21B a shásamh, ag comhbhaint reláidí príomha agus roinnt-lánú le chéile i gcothromán teorainneach amháin, agus tá sé meastar IP67. Is íobartach é don DNRH8 do chórais fotovoltaice (PV), córais stórála fuinnimh bataí (BESS), agus feidhmchláir DC tionscail, ag éascú suíomhú, ag laghdú ar earráid scuabadh, agus ag soláthar scuabadh sciobtha, iontaofa le cosaint uafriochvoltage.
