The Multiquip GELT3DIOHSINK Heat Sink/Support Rotating Diode Bridge is a genuine OEM component designed for Multiquip towable light tower models including LT12D, LT12D50B, LT12D50SA, LT12DAB, and LT6K550HZ. As a direct OEM replacement, this part is manufactured to the exact specifications of the original, ensuring a correct installation in the generator's electrical system with no guesswork on fit or function. Sourced directly through Multiquip's authorized parts supply, the part delivers the same construction and tolerances as the unit it replaces. Verify your light tower model code before ordering to confirm compatibility.
Key Features
- OEM Electrical Specification Match — Built to the exact thermal dissipation and structural support requirements of the original rotating diode bridge assembly, ensuring proper current rectification and component protection.
- Direct Drop-In Installation — Mounts to the same bolt pattern and electrical connections as the factory unit, allowing straightforward replacement within the generator head without custom adaptation.
- Broad Light Tower Fitment — Compatible with LT12D, LT12D50B, LT12D50SA, LT12DAB, and LT6K550HZ Multiquip towable light tower models.
- Protects the Diode Bridge from Heat Damage — Proper heat sinking draws thermal energy away from the rotating diode bridge during generator operation, extending the service life of the rectification system and maintaining stable AC output.
- Electrical System Safety — A failed or degraded heat sink can lead to diode overheating, rectifier failure, and uncontrolled voltage output — replacing with a genuine OEM part restores safe, stable generator performance.
The rotating diode bridge in a light tower generator converts AC voltage produced by the alternator into DC voltage used to excite the field winding, a process essential to maintaining consistent power output. The heat sink and support assembly mounts directly to the diode bridge to draw heat away from the diodes during operation, preventing thermal runaway and premature component failure. When the heat sink is cracked, corroded, or missing, the diodes can overheat rapidly, leading to rectifier failure, loss of excitation, and a generator that will not produce usable output voltage.
