SYLVANIA 51428 | QHE2x32T8/UNV PSX-MC-SC QUICKTRONIC® High-Efficiency PROStart® T8 Fluorescent Ballast

The Sylvania 51428 (QHE2x32T8/UNV PSX-MC-SC) QUICKTRONIC® Professional Series is a commercial-grade, ultra-high-efficiency **electronic fluorescent ballast** engineered to operate one or two specialized T8 linear lamp configurations. Running on a **Universal 120-277V power grid**, this premium control gear utilizes an advanced **PROStart® Programmed Rapid Start** ignition sequence that precisely preheats lamp cathodes to significantly reduce end-blackening and extend overall lamp filament life—making it highly optimized for use with occupancy sensors and frequent power cycling. Featuring a low **0.71 ballast factor (PSX)**, it delivers a fine-tuned, energy-saving light output profile that exceeds stringent **NEMA Premium Efficiency** guidelines. Enclosed in a compact **Micro-Can (MC-SC) enclosure footprint**, this heavy-duty power supply features robust sub-freezing ignition capabilities down to **-20°F (-29°C)**, rendering it an elite choice for commercial office retrofits, cold-storage facilities, and demanding outdoor architectural layouts.

PROStart® Cathode Management & NEMA Premium Energy Savings

Sylvania QUICKTRONIC® QHE series ballasts resolve the rapid lamp degradation typically caused by instant-start systems by integrating an intelligent **PROStart® microprocessor routine**. Before striking the primary gas-discharge arc, the ballast supplies a micro-timed, controlled preheating current to the T8 bi-pin cathodes. This prevents filament sputtering, maintaining absolute lumen delivery and helping system lamps achieve their full rated lifecycle even when integrated with aggressive building automation systems or ultrasonic motion sensors. Operating at a high electrical efficiency threshold, this electronic platform provides **30% to 60% energy savings** compared to traditional magnetic ballasts, while remaining 6% more efficient than basic standard-grade electronic control gears to ensure rapid payback through utility rebate incentives.

• Universal Voltage Adaptability (120-277V): Built-in sensing circuits automatically adjust to input lines ranging from 120V up to 277V, eliminating installation wiring layout errors.
• Micro-Can Compact Geometry (MC-SC): Slim, reduced-profile metal casing layout slips easily into shallow, tight luminaire pathways and specialized architectural linear channels.
• Sub-Zero Thermal Tolerance: Engineered with premium internal solid-state components, guaranteeing reliable arc strikes down to a cold **-20°F (-29°C)** temperature baseline.
• Class A Acoustic Sound Rating: Delivers exceptionally quiet operation with minimal resonant harmonic hum, making it ideal for institutional, health, and corporate spaces.

System Integration, Installation Guidelines & Code Compliance

• Wiring and Power Isolation Protocol: Before handling structural terminal blocks, routing lead wires, or unmounting old ballasts, **ensure primary power is locked out at the commercial facility circuit panel**. Follow the printed color-coded schematic on the ballast shell carefully to prevent cross-wiring lampholder sockets.
• Damp and Outdoor Location Approval: This component is UL Listed for outdoor use and damp commercial environments. When mounting inside completely exposed outdoor frameworks, such as parking lot lane pylons, backlit structural retail signs, or highway perimeter boxes, verify that the host fixture provides an airtight seal to prevent direct liquid pooling on the wire entry points.
• Remote Mounting Restrictions: The solid-state high-frequency output stages allow for flexible positioning, permitting **remote installation up to 20 feet away from the light fixture lampholders**. Use standard 18AWG solid copper lighting lead wire and clear out any physical snags or sharp framing bends to avoid localized radio-frequency interference (RFI).
• Anti-Sputter Lampholder Inspection: Programmed rapid start circuits require functional, uncorroded bi-pin contact paths to pass heating cycles accurately. Always inspect structural G13 socket lampholders during retrofits; look for signs of heat stress, carbon tracking, or pitting, and replace worn sockets to maintain full compatibility with the PROStart® cycle.
