| 4 | NPN TR(HI, GO, LO) + RS485 Output |
| 5 | PNP TR(HI, GO, LO) + RS485 Output |
| 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
