电力仪表
POWER METER
概述 /Summary
智能数显仪表适用于电力电网、自动化控制系统中对电压、电流、有功功率、无功功率、视在功率、功率因数和频率等电参量的测量,由数码管 (LED) 或液
晶 (LCD) 直接显示。具有显示直观、精度高、性能稳定、隔离性强、抗振动等优点。可选配多种扩展功能,包括 RS-485 通讯、开关量输入、开关量输出
和模拟量变送输出等,丰富的外型尺寸可方便地替代指针式仪表。
Intelligent digital display meters are used in electric power grid and automation control system to measure voltage, current, active power, reactive
power, apparent power, power factor and frequency which are displayed by LED or LCD. The meters have features of visual display, high precision,
stable performance, strong isolation, anti-vibration and so on. There are many optional functions, including the RS-485 communication, switching value
input, switching value output and analog output. Variable dimensions can be easily used to replace pointer instrument.
