Back - End Server STS Prepaid Meters 3X240V Single Phase Watt Hour Meter
The CA168-G is the non-wired model of Calin's single phase prepaid meter. It is a two-wire, 100 Amp, keypad based prepayment meter finished in a compact BS5685 footprint housing. The meter is applied for low voltage residential or small business prepayment applications.
The meter is manufactured in accordance with ISO9001 standards and IP54 rated protection class, in a wide voltage range ( Un -40% +20%) and improved RF immunity of 30V/m, allowing it to work in very harsh environments. The CA168-G series is available with measurement of both active and reactive energy, and 2400 bps baud rate optical port for data extraction.
The GPRS feature of CA168-G enables the meter to connect to the back-end server via TCP/IP or vpn through point-to-point communication networks. Metering data and grid supply parameters can be remotely read and collected into the head-end server automatically as scheduled task. The meter Information can be toggled by punch in different combinations of codes.. Users can easily retrieve metering data from the display screen such as daily usage, monthly usage, present current and voltage, balance, and last five entered tokens.
