Test key for device diagnostics allows the user to check the product for function at any time.
This frequency is compared with a frequency which is generated in the device and can be adjusted with a setting knob.
If one system phase fails, electrical drives can run on, but they can no longer reverse or restart. The measured frequency is compared with a frequency generated in the device and settable on a setting knob. By clicking on this page you are giving your consent for us to set cookies. This will prevent thermal overload due to high switching frequency, single-phase operation, impaired cooling or high ambient temperature, for example.
Original formed parts casting, sintering. System monitoring when power is fed in the system,e. DOLD measuring devices reliably monitor electrical quantities such as current, voltage, power, resistance etc. Unbalance relays, phase monitors, phase indicators Unbalance relays monitor the system for phase failure and are mainly used to protect motive-power loads.

The contacts are actuated with every current pulse and they stay in the operating position they have adopted in each case until the next pulse occurs. The products are equipped with differentfunctions depending on the application and compliance requirements. Current and temperarure monitoring f. They are very user-friendly ro9800 can be configured with only two rotary switches. Use of neutral monitors for ohmic and single-phase motive-power loads.
