Applications:
1) Three phase the meters are used to measure active or reactive energy of
three-phase circuit with refrence frequency 50Hz or 60Hz.
2) DT862, DT864, DS862, DS864 are three-phase active meters
3) DX862, DX864, DX865, DX863 are three-phase reactive meters.

Technical parameters:
1) Meters conform to GB/T 15283-1994 and GB/T 15282-1994 standards
(IEC521-1998).
2) Meters can be made into types: direct wiring and CT/PT wiring
3) Can be made into special meters according to customer's requirements
(different frequeny, voltage, current specifications, etc.)
4) Power consumption: active power consumption of voltage circuit less than 2W
(under reference conditions)
5) Dielectric properties:
a) 1.2/50 wave
b) Peak value: 6kV, no damage permitted under 10 times test.
c) Meter can withstand 2kV (circuit to earth, under 45~65Hz, 1 minute)
