Four Quadrant Smart Prepayment Meter Instantaneous Values Industrial Power Meter
As being smart meter, the core principle is getting connected, the CA368-G operates with GSM connection to the back-end server system. It is a new generation of three phase four wire prepayment watt-hour meter, allowing a maximum 100 Amp current for each phase. It is a widely applicable for light commercial and industrial prepayment applications. The meter supports load profile recording in 4 channels at adjustable interval period as well as classic metering functions. Payment mode can be altered from head-end server between prepayment mode and post-payment mode.
The meter is manufactured in accordance ISO9001 standards, allowing it to work in very harsh outdoors and indoors environments, thanks to its wide range ( Un -40% +20%) of voltage with RF immunity of 30V/m. The CA368-G series is also able to measure both active and reactive energy. A 2400 bps baud rate optical port for data interogation is also a standard configuration.
The GSM features of CA368-G enables the meter to connect with the head-end server in a two-way communication through local point-to-point GSM / GPRS networks. This design makes installation and fitting simpler and faster. A utility or service provider can read and collect metering data remotely by setting scheduled task with head-end server station with no need to pay extra to setup accessories they will not use at all. Meter information can be triggered to display by punching in different info codes..
