Multiquip M4273000003 Terminal Board (JP) - OEM Replacement Part for Super Silent Generators

The terminal board serves as the primary electrical connection interface for voltage change-over operations in Multiquip's Super Silent generator series, managing power distribution between 240V and 480V configurations. This JP-specification board integrates with the generator's wiring harness system (M4814000003) to coordinate output connections from the brushless AC generator windings through the current transformers (CT 1-5, rated 400:5A) and voltage regulation circuitry.

Engineered for the 220kW WhisperWatt platform, this terminal board facilitates the voltage change-over switch operations that allow field reconfiguration between voltage settings. The board interfaces with the automatic voltage regulator (AVR) sensing circuits and main generator output phases, supporting the open-delta excitation design that provides unlimited excitation current for maximum motor-starting capabilities. Proper terminal board function is critical for maintaining the generator's ±0.25% frequency regulation performance under load variations.

Compatible with the following Multiquip generator models:

• DCA220SSJU4F
• DCA220SSJU4F2
• DCA220SSJU4F3
