Anti - Tamper Single Phase Electric Meter , MCB connected STS Prepaid Meters
The CA168-E is a reinforced anti-tamper single phase electric meter designed on the basis of CA168 basic version. It is a keypad based compact BS footprint STS prepayment meter and credit dispenser. It is low cost but feature rich, offering a broad range of 5(80)Amp current and 30Vm RF withstand immunity , allowing it to operate in very harsh environments. The meter is applied for low voltage side small residential and light commercial metering applications.
The meter is equiped with a metal backplate for it to be fixed tightly against the mounting surface, making it hard to be tampered with. The polycarbonate fire resistant closure make this meter durable in high heat conditions. The meter is manufactured strictly by ISO9001 standards and STS encryption algorithm. It provides utilities a reliable revenue protection tool.
