BS Mounting Four Wire Three Phase Kilowatt Hour Meter With STS Compliant
The CA368 is Calin's triple phase four-wire prepayment meter. The maximum current allowed is 100 Amp per phase. It is a keypad based prepayment meter in a compact BS 5685 footprint mounting housing with a built-in load switch. The meter is applied for big residential houses, small commercial and industrial consumers.
The meter is manufactured in accordance with ISO9001 standards. It is mechanical IP54 rated, working with a broad range of voltage ( Un -40% +20%) and improved RF immunity of 30V/m, allowing it to work in harsh environments. The CA368 series provides measurement of active energy as default setting and reactive energy as optional. A 2400 bps baud rate optical communication port for data interrogation is also a standard spec.
The CA368 is also available for a split type of connection to a customer interface unit as CU. CIU is a keypad based display unit. Meter information can be triggered and displayed by input different codes. Users can easily acquire metering data such as monthly usage, daily usage, present current and voltage, balance, and last five entered tokens.
