产品概述 Product description
要治理电压扰动问题，就需先捕捉、记录、分析电压扰动现象和特征，普世通作为一家专注从事电能质量治理综合解决方案提供商，推出了本款PSTN-VDR200电压扰动监测仪产品，通常我们建议客户在一个相对持续的时间内，采用PSTN-VDR200电压扰动监测仪在线监测方式，了解自身供电系统发生电压扰动的情况，并根据监测数据分析对整个生产连续性的影响，从而找到最佳的解决方案。
To address the issue of voltage disturbance, it is necessary to first capture, record, and analyze the phenomena and characteristics of voltage disturbance. As a comprehensive solution provider specializing in power quality management, Universal has launched this PSTN-VDR200 voltage disturbance monitoring device product. We usually recommend that customers use the PSTN-VDR200 voltage disturbance monitoring device online monitoring method for a relatively continuous period of time to understand the situation of voltage disturbance in their own power supply system, and analyze the impact on the entire production continuity based on the monitoring data, in order to find the best solution.
功能特点 Function features
● PSTN-VDR200电压扰动监测仪采用高性能多核平台和嵌入式操作系统。
● 完全遵照IEC61000-4-30《测试和测量技术-电能质量测量方法》中规定的各电压相关质量指标的测量方法进行测量。

The PSTN-VDR200 voltage disturbance monitor adopts a high-performance multi-core platform and embedded operating system.
Measure in full accordance with the measurement methods for various voltage related quality indicators specified in IEC61000-4-30 "Testing and Measurement Techniques - Methods for Measuring Power Quality".
At the same time, waveform recording and frequency statistics are conducted for events such as voltage dips, surges, and interruptions.
Provide comprehensive data storage services. During normal operation, event records and waveform files (in COMTRADE format) are stored as files, which are used as backups and automatically updated in the instrument according to the principle of "first in, first out".
The instrument can simultaneously connect two sets of three-phase AC voltage for monitoring, with high cost-effectiveness.
Equipped with a 128 * 64 blue display screen and operation keyboard, human-machine interaction can be achieved locally on the instrument. The human-machine dialogue operation is all localized in Chinese, with a simple interface and easy operation.
Equipped with Ethernet communication function, it can remotely upload data through networking.
Equipped with RS-485 interface and supporting MODBUS protocol, it is convenient to connect with the backend or other systems.
The installation method is flexible, and wall mounted, embedded, or rail mounted installation can be used during use.
