The underload monitor BA 9065 of the VARIMETER series measures the phase shift between voltage and current. The phase angle changes with changing load. This measuring method is suitable to monitor asynchronous motors on underload and no load independent of motor size. Early detection of impending failtures and preventive maintenance prevent costly damage and as a user you benefit from the operational safety and high availability of your system.
Features
- According to IEC/EN 60255-1
- Current ranges up to 10 A, for higher values a CT must be used
- For AC and DC motors
- Independent of phase sequence
- Also for 400 Hz systems
- Optionally for motors with frequency converters (10 … 100 Hz) (see notes)
- Width 45 mm
