UGS-11 USY11 DC24V synchronizing relay for generator synchronization panels. Accurate voltage, frequency and phase matching for safe breaker closing.
Product Description for UGS-11 USY11 SYNCHRONIZE UNIT
The UGS-11 (USY11) Synchronize Unit, DC 24V is a high-precision synchronization controller designed for safe and automatic paralleling of generators with utility grid or generator-to-generator operation. The unit continuously monitors voltage, frequency, and phase angle between two power sources and ensures that synchronization occurs only when all electrical parameters are within permissible limits. This prevents severe electrical stress, reverse power flow, and mechanical damage to alternators, circuit breakers, and connected loads.
It provides accurate phase matching and closing signal output to the breaker, allowing seamless load transfer without interruption to critical operations.
The compact design allows easy panel mounting while the rugged electronic circuitry ensures stable performance in harsh environments such as factories, hospitals, data centers, telecom sites, and marine installations.
By minimizing human intervention, the UGS-11 improves operational safety, reduces synchronization errors, and increases generator service life. It is an ideal solution for automatic power management systems where reliability and precise control are essential. The device supports long-term operation with low maintenance requirements and is suitable for both standby and continuous generator applications.
The UGS-11 USY11 synchronization relay is a dependable, cost-effective choice for modern generator synchronization panels requiring accuracy, protection, and stable performance.
