DSS238 two phase three wire static watt hour meter (E2301)
Active energy is measured bi-directionally and reverse electricity will be measured and counted into total electricity.
Reverse indicator will light if the reverse electricity is measured.
DSS238 two phase three wire static watt hour meter(E2302A/E2302L)
These two meters could both be utilized for measuring two phase three wire or three phase three wire AC active energy. They are processed by SMT and conform to international standards of IEC62053-21 and IEC62052-11.
