The ASØ1 Auto Synchronizer module provides automatic breaker closure during generator to line synchronization, or during Peer-to-Peer bus synchronization. The ASØ1 automatically matches voltage, frequency, and phase, and is also capable of detecting a dead bus to initiate safe breaker closure from a live bus to a de-energized bus. In addition to the main synchronization circuit, the ASØ1 uses an independent built-in synchronization check circuit for maximum safety and reliability.
The ASØ1 module supports 2 analog “BUS” input channels, 7 digital input channels, and 7 digital output channels. The ASØ1 uses these I/O channels to implement high precision bus matching algorithms for generator to line or line to line synchronization. The ASØ1 is part of a distributed modular I/O system.
