Basler PRS200 Synchronizing Check Relay

Feature & Principle

It continuously samples AC voltage signals from incoming generator and bus. Internal circuit compares phase angle, voltage deviation and frequency difference. When all parameters are within adjustable setting range, the relay contact closes to allow breaker closing. It blocks closing command if out of sync, avoids huge inrush current and winding damage. It supports single-phase and three-phase system configuration.
