Voltage dip­ detection

Very short voltage dips cause some components in a heating control system to fail, while others continue to function.
Industry:
Heating, ventilation and air conditioning
Series/Measures
Voltage monitoring
Product:
E3YF400VFAL02
Data sheet:
Task:
Very short voltage dips cause some components in a heating control system to fail, while others continue to function. This interrupts the control circuit, and the system ceases to function. This should be prevented.
Solution
Undervoltage monitoring systems reliably recognise even the briefest of voltage drops and shut the complete control system down in a safe manner to prevent faults. A timing relay then starts the control system again automatically by means of a time-delay function.
Use/value:
- Prevention of faults and downtime
- Minimisation of service times
- Detection of short mains failures as comparison products
