2、Please check whether the application working condition meets the parameter requirements.
Electric actuators can fail due to improper use or under the wrong application conditions. Long-term trouble-free operation of the actuator will be ensured under the application conditions defined in the product specification.
- Supply voltage:The voltage of the power supply must be within the rated operating voltage of the actuator. Overvoltage or undervoltage may result in reduced actuator life.
- Supply current:Since the starting current of the motor is much larger than the rated current. To ensure reliable operation of the actuator, use a power supply with an output current capacity more than three times the rated current of the actuator.
- Temperature:Ensure that the actuator operates within the rated operating temperature range. Use of the actuator in environments outside of the rated operating temperature range may result in malfunction or reduced service life of the actuator, and ultimately, failure of the actuator.
- Environment:DCL switching actuators have an IP67 weatherproof rating. Generally suitable for indoor or outdoor applications. Provides a degree of protection against rain and splashing water. Protecting the actuator from rain, snow, ice, and UV (sunlight) usually extends the life of the product. Very corrosive environments may cause premature failure of electronic equipment. Do not use non-explosion proof series actuators in explosion proof environments.
- Energized persistence rate:The DCL switching actuator has an energization duration rate of 70% (42 seconds of operation per minute and must be turned off for 18 seconds), exceeding the 70% energization duration rate will cause the motor to go into overheat protection.
