BENDER继电器VME421H-D-1技术参数

BENDER继电器VME421H系列介绍

VME421H系列电压继电器设计用于监控交流和直流系统中的频率、欠压、过压以及两个阈值之间的电压（窗口鉴别器功能）。电压以有效值测量。当前测量值连续显示在液晶显示屏上。将存储导致报警继电器激活的测量值。由于响应时间可调，可以考虑特定于安装的特性，例如特定于设备的启动程序、短时电压波动等。设备版本 VME421H 从受监控的系统获取电源电压并利用内部备用能源。

特征

• 交流/直流系统的欠压、过压和频率监控，9.6…150 V (VME421H-D-1)、70…300 V (VME421H-D-2)

• 无需外部电源电压

• 综合能源备份

• 可选择不同的监控功能 < U, > U, < f, > f

• 启动延迟、响应延迟、释放延迟

• 可调开关迟滞

• 有效值测量（交流+直流）

• 通过多功能液晶显示屏显示数字测量值

• 预设功能（基本参数自动分配）

• LED：电源打开、警报 1、警报 2

• 用于操作值的测量值存储器

• 持续自我监控

• 内部测试/休息按钮

• N/C 或 N/O 操作以及故障记忆行为可选

• 设备设置密码保护

• 可密封的透明盖

• 两模块外壳（36 毫米）

• 推线端子（每个连接两个端子）

• 符合 RoHS 标准

The voltage relays of the VME421H series are designed to monitor the frequency, undervoltage, overvoltage and the voltage between two threshold values (window discriminator function) in AC and DC systems. The voltages are measured as r.m.s. values. The currently measured value is continuously shown on the LC display. The measured value leading to the activation of the alarm relays will be stored. Due to adjustable response times, installation-specific characteristics, such as device-specific start-up procedures, short-time voltage fluctuations, etc. can be considered. Device version VME421H takes the supply voltage from the system being monitored and utilizes an internal energy backup.

Features

• Undervoltage, overvoltage and frequency monitoring of AC/DC systems, 9.6…150 V (VME421H-D-1), 70…300 V (VME421H-D-2)

• Without external supply voltage

• Integrated energy backup

• Different monitoring functions selectable < U, > U, < f, > f

• Start-up delay, response delay, delay on release

• Adjustable switching hysteresis

• r.m.s. value measurement (AC + DC)

• Digital measured value display via multi-functional LC display

• Preset function (automatic assignment of basic parameters)

• LEDs: Power On, Alarm 1, Alarm 2

• Measured value memory for operating value

• Continuous self monitoring

• Internal test/rest button

• Two separate alarm relays (one changeover contact each)

• N/C or N/O operation and fault memory behaviour selectable

• Password protection for device setting

• Sealable transparent cover

• Two-module enclosure (36 mm)

• Push-wire terminal (two terminals per connection)

• RoHS-compliant
