Description
The UH 6937 speed and frequency monitor is used for safe frequency monitoring of alternating voltages. It is used for monitoring the output frequency of frequency converters or for monitoring the rotor frequency of loop rotor motors. Another area of application is the monitoring of drives in crane systems. The front display makes it easy and convenient to set the parameters for the respective application and to change them at any time.
