1.1 Introduction

1.1 Introduction
SICAM P20, P21 and P22 3-phase electronic current monitoring instruments are designed for measuring 3-
phase current of power grid. LCD screen is used. Data acquisition through RS485 is available. RS485
communication supports MODBUS-RTU protocol.
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
• Modbus-RTU
1.2

Features

This project uses high-precision sampling and metering unit and high-speed MCU data processing unit, sup-
porting high-precision, wide-range and accurate measurement and quick data analysis; segmented multi-line
WVA LCD, realizing various and abundant display; white backlight for LCD, satisfying the need for viewing data
in dark environment; NVRAM, supporting long-time data storage without data loss even in the event of power
failure; RS485 communication port and industrial standard communication protocols, realizing flexible and re-
liable communication.
