1.1

Introduction

SICAM P30, P31 and P32 3-phase electronic current monitoring instruments are designed for measuring 3-
phase current of power grid. Large-screen LCD is used. Data acquisition through RS485 is available. 

MODBUS-RTU communication protocol is supported via RS485 Serial communication port.

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.

1.2

Features

This product 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; supporting long-time data storage without data loss even in the event of power failure with 
NVRAM memory; RS485 communication port and industrial standard communication protocols, realizing flex-
ible and reliable communication.
