434951-1 Datasheet/PDF434951-1 is a widely used industrial measuring system which is found in many applications in the energy, automotive and food & beverage industries. It is a three-phase device which is primarily used for the determination of power level and frequency measurements.
Applications
The 434951-1 is mainly used for applications such as:
- Power system protection and control.
- Power quality analysis.
- Power system dynamic performance monitoring.
- Power system harmonics and tracking of transient events.
- Time-synchronised control systems.
Working Principle
The fundamental principle of the 434951-1 is using the comparison between input voltage and current signals with respect to a fixed reference. This reference is known as the ‘threshold’ and is predetermined by the user. The working principle of the 434951-1 can be broken down into four main parts which occur during the operation of the device. These are:
- Receiving the supply of energy from the mains.
- Converting the mains energy from AC to DC.
- Measuring and comparing the input voltage to the reference to make a decision.
- Acting upon the decision.
Receiving the Supply of Energy from the Mains
The 434951-1 is connected to the mains line through a transformer. This transformer reduces the AC voltage down to the working voltage of the device. This enables the output power to be generated efficiently and accurately.
Conversion of AC to DC
All inputs are then fed into a rectifier which converts the AC voltages to DC. The DC power is then stabilized and regulated by a control system which ensures accuracy and safe operation.
Measurement and Comparison
The measured input signals are compared with the pre-set reference. If it exceeds this threshold, the system triggers an alarm. The system is also able to detect if the frequency of the supply deviates too much from the norm.
Acting Upon the Decision
After the comparison is carried out, the device will make a decision as to whether the input is valid or not. If the input is deemed valid, the 434951-1 will then act upon the decision by turning on the output device. If the input is found to be invalid, the device will turn off the output device.
Conclusion
In conclusion, the 434951-1 is a very important industrial measuring system which is used in many applications. It is a three-phase device which is used for the determination of power level and frequency measurements. The fundamental principle of the 434951-1 is using the comparison between input voltage and current signals with respect to a fixed reference. The device is able to detect if the frequency of the supply deviates too much from the norm and then make a decision as to whether the input is valid or not. This decision then triggers an action from the device.
