Model: 9907-1290

Standard Voltage matching (emc) components

Features and functions

Woodward’s SPM-A Speed and Phase matching synchronizer provides automatic frequency and phase matching when used with 2301,2301A and EPG(Electric Governor) power load sharing control systems.

9907-1290 features include:

Generator synchronization

Adjustable dynamics

Frequency, phase and optional voltage matching

Optional playing time

Automatic circuit breaker closes

Optional output impedance

The 9907-1290 synchronizer is a combination mechanism of gears.

The function of the synchronizer is to reach a consistent speed and smoothly engage the gears to be engaged. Synchronizer has normal pressure type, inertia type, self-strengthening type and other forms. At present, the inertia synchronizer is widely used, which is mainly composed of joint sleeve, synchronous lock ring, etc., and is characterized by relying on friction to achieve synchronization. Inertia synchronizer is widely used in the transmission of cars and light and medium trucks, and the common structure form is lock ring.
