LINETRAXX® VME421H
- 交直流系统9.6...150 V (VME421H-D-1), 70...300 V (VME421H-D-2)的欠电压、过电压和频率监视
- 集成能源储存,由被监控系统供电
- 可选各种监视功能 U,
f - 设备设置的密码保护
- 预设功能(基本参数的自动设定)
VME421H系列电压监视仪被设计用于监视频率、欠电压、过电压和交流和直流系统中两个阈值之间的电压。 电压测量是真实有效值。电流测量值连续显示在液晶屏上。存储报警继电器激活的测量值。由于可调的响应时间,可以考虑特定于设备的特性,如特定于设备的启动过程、短时电压波动等。设备版本VME421H从监视的系统获取电源电压并利用内部能量储备。
