Power Sensor

1. Brief Introduction

1.1 Overview

The multifunctional power sensor ES730T, adopts advanced ultra-low power large-scale integrated circuit technology and high-tech products manufactured by SMT process. The key components are long-life components of international well-known brands to improve reliability and life of the product.The combined electric fire sensor ES730T is composed of safety monitoring unit and metering unit with RS485/NB communication function. In the safety monitoring, the built-in current transformer is used to monitor the remaining current, and the built-in temperature sensor is used to monitor the wire temperature. The meter has the advantages of high measurement accuracy, good stability, strong overload capacity and high reliability, widely used for monitoring & measuring safety parameters .
