Hoʻolālā ʻia ʻo DFUN DC Energy Meter no ke ana ʻana i nā ʻāpana uila i nā mea hōʻailona o kēia manawa (DC) e like me nā panela lā a me nā mea hoʻoili kaʻa ʻole no nā kaʻa uila. He kūpono hoʻi ia no nā ʻōnaehana mana DC hou a me nā ʻōnaehana hoʻoili i nā ʻoihana ʻenehana a me nā ʻoihana mining, nā hale kīwila, a me ka automation hale. 

ʻAʻole ia e hoʻomaikaʻi wale i ka ʻike a me ka mālama ʻana i ka hoʻohana ʻana i ka ikehu akā lawe pū kekahi i nā pōmaikaʻi waiwai nui a me ke kaiapuni ma o ka hoʻohana ʻana i ka ikehu.
