Woodward SPM-D10 series single circuit breaker synchronizer

Woodward SPM-D10 series single circuit breaker synchronizer

Application scenarios

SPM-D10 is a microprocessor based synchronizer suitable for three-phase AC generators equipped with Woodward or other compatible speed controllers and automatic voltage regulators. It achieves automatic frequency, phase, and voltage matching through analog or discrete output bias signals, and the model 8440-1668 SPM-D1040B/XN can directly replace the SPM-A synchronizer.

Main functions and features

Synchronization function

Capable of phase matching, slip frequency synchronization, and voltage matching.

Perform two-phase detection on the generator and busbar.

There are selectable operating modes, such as SPM-A (Run, Check, Allow, and Close).

Can perform synchronous checks and synchronous time monitoring.

Isolation operation: capable of frequency control and voltage control.

Dead bus operation: Circuit breakers can be closed as needed.

Control output

Standard configuration: There are discrete up/down outputs for speed and discrete up/down outputs for voltage.

X and XN packages: Voltage and speed analog bias outputs can be freely configured for all levels (various configurations such as ± 1V, ± 3V, 0 to 5V, 0.5 to 4.5V, ± 10V, ± 5V, 0 to 20mA, ± 20mA, etc.); The speed bias output can be configured as a 500Hz PWM output and an adjustable voltage level; Two up/down outputs can be configured as speed or voltage outputs.

Operational Characteristics

Two row LCD display screen is used for operation and alarm indication, with synchronous oscilloscope function, which can indicate control activities and circuit breaker status.

Equipped with multi-level password parameter protection function, it can be configured directly or through a PC, and the language can be adjusted between English or German.
