Product Features
Elymer SM-101 series single phase and SM-301 series three phase electronic kWh energy meters are designed to measure accurately in varying environmental field and supply conditions.
The robustness of design is verified by the fact the meters operate satisfactorily in varying ambient temperature conditions (-15oC to +55oC), varying humidity conditions (25% to 100%), voltage variation from Un (-40% to +25%), frequency variation from 50/60Hz (±10%) and power factor variation (0.3 lagging to 0.5 leading).
The circuit is developed using reliable and proven ASICs with SMT technology to suit the rough tropical environmental conditions. The meter is guaranteed to perform in Class 1 accuracy as per IS:13779 and IEC 1036 and remain unaffected in characteristics with temperature and other influencing factors over long periods in field installation.
The salient features are as described below:
-
Conform to IS:13779:1999
