2.DEDICATED CURRENT TRANSFORMER (CT)

* Dedicated current transformers (CT) are dedicated for low voltage under 440 V AC system. They can not be used for high voltage circuit.
* In each type of Eco-POWER METER excluding KW2M, KW9M and AKW8115, a combination of secondary side 5 A CTs and dedicated CTs for 5 A (AKW4801B) is used for measuring high voltage circuits; therefore, AKW4801B is definitely necessary. For details, confirm with each respective user's manual.
* Since dedicated CTs (AKW48***) cannot be used when measuring with KW2M, KW9M and AKW8115, please be careful not to purchase a dedicated CT by mistake.
* For the KW2M, KW9M and AKW8115, current transformers manufactured by U.R.D. Co., Ltd. (clamp-on type CT CTL-CL series) are recommended. Please confirm the specification beforehand.
* Dedicated current transformers (CT) are not included in Eco-POWER METERs.
* Each dedicated current transformer (CT) includes a 1 m 3.28 ft relay cable, respectively.
