GH302

GH302 is an electronic three-phase electric meter for measuring active electrical energy, compliant with the FNN specification (1.4.1). In its basic configuration, it is designed to measure active electrical energy in consumption and supply in accuracy class A in four energy metering modes. It also meets the requirements for a single-phase operation for each individual phase.

Installation in the network is done by placing the meter and on the installation adapter. The electricity meter contains two independent communication interfaces. Optical interface according to IEC standard (identified as INFO) and RS485 optical interface identified as LMN. The INFO interface also functions as an optical call button where a hand-held torch can be used to control and navigate the instrument menu. Communication with the master system is provided by the LMN interface. This is a data communication channel enabling connection to SMGw. The communication speed is 921600Bd. The display unit of the LC display has two lines in the basic view providing two information sets. Billing-related information – billing data and a set of informative non-billing data. These are intended for the end customer only. This set includes the current power, historical values (1d, 7d, 30d, 365d) and the power consumption value since the last reset (E register). The values for the end customer are protected by a PIN code.

The electricity meter is approved for operation in a metering system with SMGw.
