SPM-D21 (ASG 421)

Two Breaker Synchronizer / Load Control

The SPM-D21 is a microprocessor-based synchronizer designed for use on three phase AC generators equipped with Woodward or other compatible speed controls and automatic voltage regulators. The SPM-D21 provides automatic frequency, phase and voltage matching using either analog or discrete output signals.
It combines synchronizing for a generator circuit breaker (GCB) and a mains circuit breaker (MCB), load and power factor control, and generator and mains protection.
