Single Phase 2 Wire STS Prepaid Meters Emergency Credit Prapayment Enery Meter
Calin designs and produces prepaid electric meters which are cost-efficient and ideal for the use in solutions for AMR/AMI at residential as well as industrial applications.Calin's prepaid meters own anti-tamper features . The meter is built with multi sensors and triggers. including tamper shutdown protection ,disconnects on overload and no credit .
CA168 mono phase prepaid meters is a perfect solution for middle income consumers and is ideal for retrofitting installations. When the residual energy is 0 or the allowable overdraft that both sides agreed, this meter will send out power-off signal to have load switch cut off power. The power will be recovered automatically after inputting new purchased energy amount.
As tamper as the major cause of non-technical loss, Calin's prepaid meters are all provided with anti-tamper features. The meter is built with multi sensors and triggers. Any illegal intrusion will trigger visual and audio alarm and the inside contactor will disconnect the load if the user will not compromise within preset time period. The tamper will be recorded with a time stamp within meters' non-volatile memory as proof for future data collection.
