Multiquip B5130000103 DCA-70USI Generator Assembly - OEM Replacement Part

This complete generator assembly is the core power generation unit for the DCA-70USI Ultra Silent 56kW portable generator system. Designed for high-demand applications including telecom sites, lighting facilities, power tools, and submersible pumps, this assembly features Multiquip's advanced Open-Delta excitation system that provides superior voltage regulation during heavy loads and motor starting conditions.

The Open-Delta excitation system includes an electrically independent winding configuration with four connections (A, B, C, and D) that automatically adapts to load conditions. During steady-state operation, the system supplies power through parallel connections (A to B, A to D, and C to D), providing stable three-phase voltage regulation. When heavy loads such as motor starting or short circuits occur, the automatic voltage regulator switches to series configuration (B to C), adding phase voltages to deliver higher excitation current for maximum performance and load handling capability.
