【英文介绍】

The unit is from the Woodward digital Synchronizer and Load control family. It is designed for use with Woodward speed controllers (or other compatible devices) and automatic voltage regulators for parallel, synchronous, load and unload three-phase AC generator sets.

9905-704 Some of the load control features of the DSLC controller include:

Frequency trimmer function for precise frequency control in synchronous load distribution systems

Simple load drop operations provide safe operation in parallel bus applications

Adjustable load switch output with independent pick up and pressure drop points

Load raises and lowers input to adjust speed before synchronization

Voltage increases and decreases the input to adjust the voltage before synchronization

The device has three-phase true RMS power detection, which ensures accuracy even in the case of voltage fluctuations and phase load imbalance. The 9905-704 DSLC controller has a rated input voltage of 240 Vac and a speed bias of +3.0 Vdc. The controller is rated for operating temperatures of -40 to +70 °C (-40 to 158 F) and storage temperatures of -55 to +105 °C (-67 to 221 F).

Some synchronizer features include:

Delay automatic multi-color reclosing

Voltage matching

Automatic resynchronization

Synchronizer timeout alarm
