Notes :
1) | Dedicated CT are dedicated for low voltage under 440 V AC system. They can not be used for high voltage circuit. |
---|---|
2) | In each type of Eco-POWER METER excluding AKW8115, KW9M and KW2M, a combination of commercially secondary side 5 A CTs and dedicated CTs for 5 A is used for measuring high voltage circuits; For details, confirm with each respective user's manual. |
3) | Since dedicated CTs cannot be used when measuring with AKW8115, KW9M and KW2M, please be careful and do not purchase a dedicated CT by mistake. |
4) | For the AKW8115, KW9M and KW2M, CT with a secondary side current 1 A or 5 A is recommended. Please confirm the specification beforehand. |
5) | Dedicated CT are not included with Eco-POWER METERs. |
6) | Each dedicated CT includes a 1 m 3.281 ft relay cable, respectively. |
