The Woodward SPM-D Series are microprocessor-based synchronizers designed for use on AC generators equipped with Woodward or other compatible speed controls and automatic voltage regulators, providing automatic frequency, phase, and voltage matching. Drake Controls supplies, configures, and services the SPM-D synchronizer family as a Woodward Authorized Distributor.
SPM-D10 Series
A microprocessor-based synchronizer designed for use on three-phase AC generators equipped with Woodward or other compatible speed controls and automatic voltage regulators, providing automatic frequency, phase and voltage matching using either analog- or discrete output bias signals.
SPM-D11 Series
Microprocessor-based synchronizers for one- or three-phase AC generators, providing automatic frequency, phase, and voltage matching. Combines synchronizing for one circuit breaker, load and power factor control, or isochronous load sharing and generator protection.
SPM-D21 Series
Microprocessor-based synchronizers for three-phase AC generators, providing automatic frequency, phase and voltage matching. Combines synchronizing for a GCB (generator circuit breaker) and a MCB (mains circuit breaker), load and power factor control, and generator and mains protection.
