Power Care

A SERYU Star-Delta timer is a digital relay used in star-delta starter systems for safe and efficient three-phase motor startup. It allows for adjustable transition and delay times, ensuring proper switching between the star and delta connections. The timer also offers alternative supply voltages and double contact outputs for various system applications. Functionality:

• Star-Delta Switching:The SERYU timer controls the switching sequence between the star and delta connections of a three-phase motor during startup. 
• Adjustable Transition Time:The timer allows for adjusting the time it takes to switch from the star to the delta connection, typically between 20ms and 500ms. 
• Adjustable Delay Time:A delay time can be set between 1 and 60 seconds, allowing the motor to run in the star configuration for a specified duration before switching to delta. 
• Reduced Starting Current:By initially running the motor in a star configuration, the SERYU timer reduces the starting current and voltage surges, protecting the motor and connected equipment. 

Key Features:

• Digital Technology: SERYU is a digital relay, providing precise and reliable timing control. 
• Flexible Power Supply: It offers alternative supply voltages (24VDC and 230VAC), making it suitable for both AC and DC systems. 
• Double Contact Output: The double contact output allows for various automation applications and feedback signals. 
• Durable and Maintenance-Free: Some versions are designed to be durable and require minimal maintenance. 

Applications:

• Three-Phase Motor Starters:Primarily used in star-delta starters for controlling the switching sequence during motor startup.
