双抽头变压器? 有1个ACME的双触头变压器 480/240V输入,240/120V输出,容量是5KVA。印度人说如果使用120V输出,可用的容量是2.5KVA,请问这是为什么?讲的简单点,谢谢。 LBM: TRANSFORMER 5000VA - (480/240-120V) –ACME part# TA-83224 , this model will not give us full 5KVA , as secondary voltageis 240 V and through center tapping of Transformer we are getting 120V. We are using only 1hot and center tap to get 120V , remaining 2nd hot we are not usingin parallel hence we are using only half of the Transformer capacity查看更多1个回答 . 5人已关注
