C.T( Current Transfomers)
※ Spec 01 and 02 use general current transformer and users must set current transform ratio(Refer to setting method of current transform ratio)
spec 03 ~ 12 are accurate measuring wattmeter which uses H series C.T of accuracy 0.2%.

Cautious)spec of 03 ~ 12 cannot use general current transformer and it is unnecessary to set current transform ratio .
– Type of measuring spec is single phase 2 lines and when current transformer is 200 A : 5 A, then please purchase WM2-101 and use it. (if current transformer is 200A : 1A then please use WM3-101)
– Initial current transformer setting for spec 01 and 02 is set with 100 A
– Output spec 0 ~ 5 are option
– PV (output displaying value)
– RS485 output spec is coming soon
