How to Avoid Voltage Abnormalities in 220V Electric Valve Actuators?

To prevent voltage abnormalities in 220V electric valve  actuators , the following measures can be taken:
Install a voltage stabilizer: If the power supply voltage fluctuates significantly, a voltage stabilizer can be installed to stabilize the voltage. The stabilizer automatically monitors the input voltage and maintains the output voltage within the set range, effectively preventing damage to the electric valve Actuator caused by excessive or insufficient voltage.
Using an Uninterruptible Power Supply (UPS): For applications with high requirements for power stability, a UPS can be installed. It not only provides temporary power support during mains outages but also purifies and stabilizes the input mains power, reducing voltage fluctuations and interference.
Regularly inspect power lines: Periodically check the power supply lines for issues such as damage, aging, or poor contact. If any problems are found, promptly replace or repair the damaged wiring to ensure stable and reliable power transmission. Additionally, ensure that all terminal connections are secure to prevent contact resistance caused by looseness, which may lead to voltage drop or fluctuations
Reasonable selection of cable specifications: Choose the appropriate cable specifications based on the power and installation distance of the electric valve Actuator. The cross-sectional area of the cable should be large enough to reduce line resistance and avoid excessive voltage drop caused by long-distance transmission or high current.
 
Install overvoltage and undervoltage protection devices: Install overvoltage and undervoltage protection devices in the control circuit of the electric valve actuator. When the voltage exceeds or falls below the set threshold, the protective device will automatically cut off the power or take corresponding protective measures to prevent the actuator from being damaged due to abnormal voltage.
 
Avoid sharing the same power line with high-power equipment: High power equipment may cause fluctuations in power supply voltage during startup and operation, and electric valve actuators should be avoided from sharing the same power line with such equipment as much as possible. If it cannot be avoided, isolation measures can be taken, such as using isolation transformers, to reduce mutual interference.
Monitoring power quality: Regularly monitor the voltage, frequency, harmonics, and other parameters of the power supply using power monitoring equipment to promptly identify potential power quality issues. Once abnormal voltage is detected, immediate investigation and handling should be carried out to identify the root cause of the problem and take corresponding solutions.
 
Follow installation specifications: When installing electric valve  actuators , strictly follow the Detsen product manual and relevant installation specifications to ensure correct installation. Incorrect installation may lead to poor electrical connections, poor heat dissipation, and other issues, affecting the normal operation of the actuator and even causing voltage abnormalities.
