Sylvania 49171 QTP1x28T5/UNV PSN

The Sylvania Quicktronic® Professional 49111 (QTP1x28T5/UNVPSN) Ballast is a commercial-grade, high-frequency electronic control gear module engineered to operate a single standard-output linear T5 fluorescent lamp. Designed with a universal voltage framework auto-sensing 120–277V grids, this high-performance module utilizes advanced PROStart® programmed rapid start technology to safely condition cathode filaments prior to gas discharge ionization. Outfitted with integrated QUICKSENSE® end-of-lamp-life circuitry, a normal ballast factor profile, and a low-profile elongated housing, it provides a whisper-quiet Class A sound rating for architectural office troffers, commercial retail displays, and institutional classroom pendants.

ADL Supply Expert Application & Replacement Guide

The Sylvania QTP1x28T5/UNVPSN electronic ballast is an established industry property maintenance standard specified widely across architectural offices, school corridors, and commercial interiors running dedicated 1-lamp linear configurations. By coordinating ignition outputs cleanly over Sylvania PENTRON® series lamps, this module secures full rated lumen outputs while optimizing visual delivery without the annoying stroboscopic rolling shadows or line humming common in traditional systems.

Critical Un-Shunted Lampholder Mandate and Wire Insertion Controls: Maintenance crews and field technicians executing routine facility upkeep sweeps must inspect existing luminaire internal wiring parameters closely prior to checkout: this programmed rapid start ballast strictly mandates the use of un-shunted lampholders at the fixture sockets. Un-shunted sockets isolate the left and right pin contact tracks, allowing the ballast to pass an independent, low-voltage conditioning current to safely warm the tube filaments before firing the primary gas discharge arc.

Forcing a Programmed Start device onto old shunted sockets (common in legacy Instant Start layouts where pins are internally bridged) short-circuits the preheat leads, causing immediate ballast overheating, rapid component degradation, or complete circuit board non-performance. This module features quick push-in terminal connectors designed to grip 18AWG solid copper lines securely; no lead wires are included with the loose ballast casing block.
