1.1 Introduction

1.1 Introduction
SICAM P38 & P39 3-phase Multi-function Power Meter integrate measurement, record, power metering,
remote communication and control, large screen LCD and network communication functions. This meter can
measure various parameters of power grid, such as voltage, current, power, power factor and frequency. It is
provided with 2
active and reactive energy. It has multi-tariff energy and multi-tariff demand functions. P38 has two independent
RS-485 ports; P39 has 1 RS-485 & 1 Ethernet port. Device supports MODBUS-RTU protocol (serial & TCP/IP).
Besides, it has binary input and output.
This product is extensively applicable to power substation and distribution automation system, industrial control
and industrial automation system, energy management system and community power monitoring, etc.
This 3-phase electronic multi-function power meter meets following standards:
• IEC 62052-11:2003 (Electricity metering equipment (a.c.) General requirements, tests and test conditions-
Part 11: Metering equipment) standard
• IEC 62053-22:2003 static meters for active energy (classes 0.2 S and 0.5 S)
• IEC 62053-23:2003 static meters for reactive energy (classes 2 and 3)
• Modbus-RTU
