Open Delta Excitation System

The DCA-15SPX3 generator is equipped with the state of the art "Open-Delta" excitation system. The open delta system consist of an electrically independent winding wound among stationary windings of the AC output section.

There are four Leads: A, B, C and D. During light loads, the power to the Automatic Voltage Regulator (AVR) is supplied from the leads of B & C, when loads increase, the AVR switches and accepts power from leads A & D. The output of leads A & D increase proportionally with load. This has the effect of adding the voltages of each phase to provide better voltage response during heavy loads.

The connections of the AVR to the AC output windings are for the sole purpose of sensing only. No power is required from these windings.

The open-delta design provides virtually unlimited excitation current due to its independent power supply offering maximum motor starting capabilities. The excitation does not have a "fixed ceiling" and responds according the demands of the required load.

Engine

The DCA-15SPX3is powered by a 4-cylinder KUBOTA Model V2203 diesel engine.This engine is designed to meet every performance requirement for the generator. Reference Table 5, page 19 for engine specifications.

In keeping with MQ Power's policy of constantly improving its products, the specifications quoted herein are subject to change without prior notice.
