商用储水式电热水器变压器检查办法一
2016-11-29 11:16:16

       商用储水式电热水器控制电路合用电压为110/120V,50/60Hz及24V,50/60Hz。

       本部分包罗对电子掌握式商用热水器的110/120VAC和24VAC控制电路变压器线路状况的检查步调110/120V&24VAC控制电路变压器线路

        110/120V&24V AC控制电路变压器是多输出变压器,二次绕组能够输出两个差别的电压值。此款变压器二次绕组输出电源为110/120VAC和24VAC两种,为CCB电路板和UIM供给电源。其一次绕组的输入线路规格必需与商用储水式电热水器电源线路符合。不正确的线路规格会招致二次绕组输出的电压过低或太高,从而能够惹起接触器震颤(频仍开关),永久性破坏接触器和/或CCB电路板。

 

商用储水式电热水器变压器额定输入电压为400VAC,接线端口为10,11.将其连接于与商用储水式电热水器电源电压相婚配的终端。变压器有2种电压输出,20,21端口输出电压为110/120VAC,22,23端口输出电压为24VAC,接线时将其连接于与输出相婚配的配电元件终端。
