Universal M1000ML5AC5M-500K

The Universal Triad® M1000ML5AC5M500K Ballast Kit (P/N #54964) is an industrial-grade, heavy-duty magnetic core-and-coil HID replacement engine engineered to operate a single 1000-watt probe-start metal halide lamp. Utilizing a robust Constant Wattage Autotransformer (CWA) circuit configuration, this high-power magnetic autotransformer delivers excellent voltage regulation to insulate the lamp arc from severe building power sags. Outfitted with an expansive **5-Tap terminal lead array handling 120V, 208V, 240V, 277V, or 480V line configurations**, it serves as the primary choice for industrial manufacturing centers, high-clearance shipping yards, high-bay warehouses, and outdoor stadium flood lighting towers.

ADL Supply Expert Application & Replacement Guide

The Universal Douglas M1000ML5AC5M500K 5-Tap ballast kit is an established high-output industrial building maintenance standard specified heavily for high-ceiling industrial manufacturing lines, steel foundries, marine terminals, open athletic arenas, and commercial site parking security towers. Purpose-built to serve as a complete drop-in replacement engine to supercede obsolete core blocks (including old catalog tracking identifiers 113083R and 113038), this pre-assembled maintenance package includes heavy-duty zinc-plated structural brackets, hardware fasteners, and a matching oil-filled power-factor correcting capacitor to accelerate maintenance cycles.

Critical Probe-Start Circuit Balancing and Ignitor Exclusion Boundaries: Electrical contractors executing field replacements must evaluate the exact technical limits of the **ANSI M47 circuit code footprint**. This specific module is engineered strictly for traditional probe-start metal halide bulbs. A probe-start lamp utilizes an integrated internal starter electrode built directly inside the quartz arc capsule to strike the initial plasma path. **Consequently, this ballast does not require and must never be wired alongside an external solid-state ignitor box**.

Trying to splice an ignitor into this CWA circuit track will alter the impedance balance and trigger immediate terminal coil melting or flash-weld the lamp contacts. Wire routing should follow the explicit color-coded diagram stamped on the transformer face plate, ensuring that unused voltage line tap leads are individually insulated with wire nuts and capped to at least 600V to stop high-voltage arc-over tracking faults inside the luminaire ballast compartment.

Operation, Safety & Mounting Compliance

Constant Wattage Autotransformer Line Voltage Stabilization

By implementing a continuous CWA magnetic transformer loop working alongside its integrated oil-filled capacitor, this module isolates the burning high-pressure arc column from sudden building grid voltage sags. The CWA circuit maintains a steady lamp operating wattage output variance of within $\pm10\%$ even when primary line voltage swings fluctuate broadly by up to $\pm10\%$ across building legs. This regulation prevents the lamp from suddenly extinguishing (dropping arc) when heavy industrial inductive machinery, HVAC chillers, or heavy motors cycle on adjacent branch tracks.

Chassis Lead Extensions and Thermal Safety Mounting

During core change-outs inside deep high-bay fixture housings, installers must tighten the steel bolts through the core plates to anchor an unbroken, low-impedance equipment grounding track. This component features an elite Class H insulation wrap layer rated to absorb persistent thermal stress peaks up to $180^\circ\text{C}$. Lead wire pathways exiting the transformer coils are 18 AWG copper wires pre-insulated to withstand line-voltage potentials up to 600V AC. Maintain a maximum remote lead distance to the Mogul porcelain socket of 18 feet when executing remote mounting configurations away from high-bay fixture heads.
