MAN TGX Voltage Converter ECU 24V/12V 36A 81259070338 81259070324 81259070348 Other Engines & Components

Description:
Genuine MAN voltage converter ECU 24V to 12V, designed for MAN TGS and TGX trucks. This module (MAN-Nr. 81.25907-0338 / 81259070338, supplier code A1210-003-03 by Seuffer) converts the vehicle’s 24V electrical system down to a stabilised 12V supply, typically rated to 36A, for powering cab accessories and electronic equipment. It is mounted inside the cab on a metal bracket with a transparent plastic shield for protection. The unit features a multi-pin main connector and two auxiliary sockets, with integrated cooling ventilation in the red plastic housing.

The part offered here is a used original MAN / Seuffer module, removed from a donor MAN TGS/TGX Euro 5/Euro 6 truck and verified against the OE reference numbers 81259070338, 81259070324, 81259070348, 81.25907-0338, 81.25907-0324, 81.25907-0348 and A1210-003-03. It was tested on the vehicle prior to dismantling to confirm correct voltage conversion and stable output. Visual inspection shows only minor cosmetic wear to the housing, bracket and plastic shield, with intact connectors and mounting points.

This converter ECU is suitable for many MAN TGS and TGX models from around 2007-onwards with Euro 5 and Euro 6 D20/D26 engines, where these OE numbers are specified. Please match the part number and connector layout with your existing unit before ordering, as there are several similar MAN converters.
