Multiquip M4273000003 Voltage Change-Over Board

The Multiquip M4273000003 is a genuine OEM Voltage Change-Over Board designed for the DCA220SSJ, DCA220SSJU, DCA250SSI, DCA250SSIU, DCA220SSVU, DCA220SSCU, and related DCA super-silent generator series. As a direct Multiquip OEM component, part M4273000003 is manufactured to the same specifications as the original board it replaces, ensuring correct voltage switching behavior and full compatibility with the generator's control system. Fitment covers a wide range of DCA220 and DCA250 ultra-silent and super-silent configurations, including Tier 4 variants such as the DCA220SSJU4F, DCA220SSJU4F2, DCA220SSJU4F3, and DCA220SSCU4I.

Key Features

• Genuine OEM Electrical Specification — Manufactured to the original circuit and switching specification for the DCA-series generator, ensuring the board operates at the correct voltage range and control logic without adaptation.
• Direct-Fit Replacement — Designed to mount and connect in the same position as the original board, with matching connector points for a straightforward swap during scheduled maintenance or field repair.
• Broad DCA Series Coverage — Fits DCA220SSJ, DCA220SSJU, DCA220SSVU, DCA220SSCU, DCA250SSI, DCA250SSIU, and Tier 4 variants including DCA220SSJU4F, DCA220SSJU4F2, DCA220SSJU4F3, and DCA220SSCU4I.
• Voltage Output Integrity — A correctly functioning change-over board allows the operator to reliably select and switch between output voltage configurations; a failed board can cause incorrect voltage delivery or complete loss of switchable output.
• Electrical Safety Compliance — Voltage switching components in generator systems must meet precise control tolerances; using a genuine OEM board ensures the switching circuit performs within the design parameters of the generator's electrical architecture.

The Voltage Change-Over Board is the control component that allows the generator's output voltage to be selected or switched between configurations — typically between different voltage settings required by the connected load or site electrical standard. It sits within the generator's electrical panel and manages the routing of output power to match the selected voltage mode. When this board fails or develops a fault, the generator may be unable to deliver the correct voltage, produce inconsistent output, or lose the ability to switch modes entirely, which can interrupt power-dependent operations on site.
