The Multiquip M1000120AC5M Ballast Transformer 60Hz is a genuine OEM component designed for LT12, LT12P, LT12D, and SLT12D series light towers. As a direct OEM replacement, this part meets the original electrical specifications required to properly drive the lighting system on your Multiquip tower. Sourced directly from Multiquip, the part ensures a drop-in fit with the existing wiring harness and lamp housing — no improvised adapters or modifications needed. If your light tower is producing dim output, flickering, or no output at all, the ballast transformer is one of the first components to inspect and replace.
Key Features
- Correct 60Hz Electrical Rating — Matched to the 60Hz power frequency used in North American light tower applications, ensuring stable arc lamp ignition and consistent luminous output.
- Genuine OEM Construction — Manufactured to Multiquip's original transformer specifications, including proper impedance and voltage step-up characteristics for the lamp type used in these towers.
- Direct-Fit Replacement — Designed to integrate with the existing lamp circuit on LT12, LT12P, LT12D, and SLT12D light towers without rewiring or bracket adaptation.
- Restores Full Lighting Performance — A failed or degraded ballast causes flickering, failure to strike, or dim lamp output; replacing with M1000120AC5M brings output back to full rated brightness.
- Electrical Safety Compliance — As a core component in the high-voltage lamp ignition circuit, using a correctly rated OEM transformer is critical to safe operation and avoiding damage to downstream lighting components.
A ballast transformer regulates and steps up the electrical current delivered to the arc lamps in a light tower, providing the high-voltage spike needed to strike the arc and then stabilizing the current to sustain steady lamp operation. Without a properly functioning ballast, the lamp will either fail to ignite or burn inconsistently, significantly reducing site illumination. Over time, ballast transformers can degrade due to heat cycling and electrical stress, making prompt replacement essential to keeping the light tower operating at full output during night work or low-visibility conditions.
