GE 49775 GE232MAX-H/ULTRA 74803

The GE UltraMax® 49775/74803 (GE232MAX-N/Ultra) Ballast is a commercial-grade, multi-voltage electronic control gear module engineered to operate one or two standard or energy-saving T8 linear fluorescent lamps. Designed for universal 120–277V systems, this high-performance ballast utilizes optimized Instant Start technology to deliver immediate, flicker-free ignition while minimizing systemic energy draw. Outfitted with an active power factor correction circuit and independent parallel lamp operational paths, this normal ballast factor (0.87 BF) module serves as the industry standard for general-purpose fluorescent troffers, commercial strip fixtures, and office workspace maintenance.

ADL Supply Expert Application & Replacement Guide

The GE UltraMax 49775/74803 control gear is an industry facility footprint standard specified heavily by commercial electrical contractors, real estate engineering teams, and facility maintenance divisions. Operating with an optimized high-frequency circuit architecture, this ballast is engineered for continuous-run applications, providing full light delivery while slitting systemic energy overhead. The normal 0.87 ballast factor represents the ideal architectural baseline—delivering balanced, full-rated lumen punch without over-driving fixtures or inflating monthly utility costs.

Critical Shunted Lampholder Mandate & Parallel Circuit Boundaries: Field electricians executing routine facility lighting swaps must evaluate socket configurations closely prior to termination: this Instant Start electronic ballast requires shunted lampholders at all terminal connection points. Shunted sockets incorporate an internal metal bridge that joins the left and right pin tracks, allowing the ballast to send its immediate high-voltage strike slice across the gas column cleanly. Inserting an Instant Start ballast into un-shunted sockets (common in Programmed Start fixtures) will break the output pathway, causing ignition failure, high-resistance arc faults, or immediate terminal component damage.

Furthermore, this module utilizes a premium Parallel Lamp Operational architecture. Unlike legacy series-wired ballasts where a single filament blowout kills the entire fixture loop, this control gear operates independent channels. If lamp one drops out, the remaining tube continues to burn at full efficacy, dramatically slashing operational labor tracking costs by allowing maintenance teams to structure routine group re-lamping sweeps.

Operation, Safety & Mounting Compliance

High-Frequency Electronic Signal Transformation

This electronic assembly converts raw municipal alternating current into high-frequency ballast outputs exceeding 42 kHz, completely eliminating stroboscopic workplace eye fatigue and structural flickering loops common in old magnetic systems. It incorporates an automated active surge insulation barrier that blocks standard utility switching transients and operational spikes from breaking down sensitive internal solid-state board capacitors.
