概述 Overview

数字屏装电压表适用于电力电网、自动化控制系统，主要测量电网中的电压，按照其附加功能划分，我们拥有X、K 系列数显仪表。

X 系列智能数显电压表，是通过直接交流采样，并采用真有效值算法测量电压，并由数码管(LED) 直接显示的数字式电量仪表。

K 系列智能仪表则是在X 系列基础上可选配1-3 路模拟变送输出(4-20mA 等) 及一路RS-485 通信接口输出( 采用Modbus-RTU 协议)，1-4 路开光量输入测

量功能( 实现“遥信”) 和1~2 路继电器报警输出功能( 实现“遥控”)， 以方便组网的数显仪表，并且可以直接三排数码显示或者单排数码管显示。

从测量的电力网络分，还可以分为单相电压表和三相电压表，单相电压表为单排数码显示。三相电压表为单排或三排数码显示。

The digital screen-mounted voltmeter is suitable for power grids and automated control systems, primarily used to measure voltage in the grid. Based on its additional functions, we offer the X and K series digital displays.

The X series intelligent digital voltmeter is a digital power meter that directly samples AC voltage, measures it using a true RMS algorithm, and displays the readings via a digital display (LED).

The K series intelligent instruments can be optionally equipped with 1-3 analog transmitter outputs (such as 4-20mA) and one RS-485 communication interface output (using Modbus-RTU protocol) on the basis of the X series. They also feature 1-4 discrete input measurement functions (for "remote signaling") and 1-2 relay alarm output functions (for "remote control"), making them suitable for networked digital displays. Additionally, they support direct three-row digital display or single-row digital tube display.

In terms of measurement, power networks can also be categorized into single-phase voltmeters and three-phase voltmeters. Single-phase voltmeters feature single-row digital displays, while three-phase voltmeters have either single-row or triple-row digital displays.
