Ang DNRH8 Combined Switch ay isang all-in-one na solusyon para sa pag-switch ng DC load at paghihiwalay, na may rating hanggang 1500 VDC at 630 A. Ito ay disenyo upang matugunan ang mga kategorya ng paggamit na DC-PV1, DC-PV2, at DC-21B, na naglalaman ng pangunahing at pre-charge relays sa isang compact, IP67-rated na housing. Ideal para sa mga photovoltaic (PV) systems, battery energy storage systems (BESS), at industriyal na DC applications, ang DNRH8 ay nagpapadali ng pag-install, binabawasan ang mga error sa wiring, at nagbibigay ng mabilis at maasahan na pag-switch na may undervoltage protection.
Voltage & Current: DC 1500 V, operational current 200 A–630 A.
Switching Capacity: Making/withstand capacity 15 kA (0.1 s) / 10 kA (1 s); conditional short-circuit current 100 kA.
Arc Performance: Minimized na arc distance; arcing time < 3 ms.
Protection Rating: IP67 (external); IP20 (internal).
Control Modes: Manual o 24 V remote control na may auto/manual selection.
Undervoltage Module: Active/passive trip options (response < 0.5 s, 2 min power-loss backup).
Optional Relay Module: JDQMK series na naglalaman ng main/pre-charge relays at resistors.
