LINETRAXX® VME420

LINETRAXX® VME420

  • 0...300V的交直流欠电压、过电压和频率监视仪
  • 各种监视功能可选< U, > U, < f, > f
  • 可调启动延迟,响应延迟和释放延迟
  • 设备设置的密码保护
  • 预设功能(基本参数的自动设定)

VME420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。存储触发报警继电器所需的测量值。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。监视仪需要外部电源电压。
