Lightening protection STS Prepaid Meters , Backlit LCD 3 Phase Kwh Meter

The CA368 offers options for extended surge protection for lightening up to 16kV with a build-in  8kA VDR. It is intended for unstable grid voltage envrionment such as African and Central American continent. The meter works in a three phase four wire or three wire (optional) network with 100 Amp per phase, and 30 Vm withstand of RF immunity, allowing it to operate in very severe envrionments. It is a perfect revenue protection device for submetering of residential, light commercial and industrial applications. 

The CA368 allows a utility and service provider to make flexible payment control settings such as free basic unit, emergency overdraft credit, low credit waring, repayment rules. This feature enables the service providers to secure their revenue through dynamic contractual control.
