Universal B454PUNV-E

Universal AccuStart5 B454PUNV-E – 1–4 Lamp F54T5HO / 3–4 Lamp FT50W or FT55W | 120–277V | Programmed Rapid Start

The Universal AccuStart5 B454PUNV-E is a universal-voltage programmed rapid-start electronic ballast designed to operate one through four F54T5HO lamps, three or four FT50W/2G11 lamps, or three or four FT55W/2G11 lamps. It accepts 120–277V AC input at 50/60Hz, uses active power-factor correction, supports series-parallel lamp operation, and incorporates automatic-reset end-of-lamp-life shutdown circuitry. The ballast also supports selected lamp-switching configurations through its control leads. Please verify ballast model, lamp family, lamp quantity, wiring diagram, input voltage, dimensions, and fixture grounding before ordering.

Key Features & Benefits

• Operates one through four F54T5HO lamps from a single ballast.
• Also supports three or four FT50W/2G11 or FT55W/2G11 long compact fluorescent lamps.
• Universal 120–277V input simplifies use across commercial and industrial electrical systems.
• Programmed rapid start helps support lamp life in frequently switched applications.
• Automatic-reset end-of-lamp-life shutdown circuitry protects the ballast and fixture after lamp failure.
• Active power-factor correction supports high power-factor operation across approved lamp combinations.
• Series-parallel lamp operation supports the manufacturer’s documented multi-lamp switching configurations.
• Remote mounting is permitted up to 20 feet where the application and wiring comply with manufacturer requirements.

Product Overview

The Universal AccuStart5 B454PUNV-E is designed for high-output T5 and long compact fluorescent fixtures that require flexible lamp-count operation and universal input voltage. It can power one, two, three, or four F54T5HO lamps, making it suitable for multi-lamp commercial fixtures and maintenance replacements where the original wiring and lamp configuration match the Universal diagram.

The ballast also supports three- and four-lamp FT50W/2G11 and FT55W/2G11 systems. Because ballast factor and input wattage vary by lamp family and lamp count, the exact fixture configuration must be verified rather than assuming all supported lamps operate identically.

Manufacturer wiring diagrams show selectable lamp switching using the grey lead and an external switch, occupancy sensor, relay, or other approved control device. When switching is not used, the specified control leads must be connected according to the Universal wiring instructions.

Compatible Applications

• Four-lamp F54T5HO high-bay and commercial fixtures
• One-, two-, three-, or four-lamp T5HO luminaires
• Three- or four-lamp FT50W/2G11 fixtures
• Three- or four-lamp FT55W/2G11 fixtures
• Commercial warehouses and industrial facilities
• Retail, institutional, and large-area fluorescent lighting
• Maintenance replacement and ballast retrofit projects requiring B454PUNV-E compatibility
• Fixtures using approved lamp-switching or occupancy-control configurations

Before Ordering – Verify

• Model number: Confirm the required ballast is B454PUNV-E.
• Lamp family: Verify the fixture uses F54T5HO, FT50W/2G11, or FT55W/2G11 lamps.
• Lamp quantity: F54T5HO configurations support one through four lamps; FT50W and FT55W configurations support three or four lamps only.
• Input voltage: Confirm the branch circuit is within 120–277V AC, ±10%, 50/60Hz.
• Wiring: Compare the fixture wiring to the manufacturer diagram before disconnecting the original ballast.
• Lamp switching: Verify whether the fixture uses the SW control circuit. Do not leave control leads incorrectly connected.
• Three-lamp wiring: The manufacturer instructs installers to cap the specified unused Blue/White or Orange lead individually.
• Dimensions: Confirm 16.88-inch overall length, 1.82-inch width, 1.18-inch height, and 16.28-inch mounting centers.
• Case temperature: Verify that fixture thermal conditions keep the ballast case at or below 90°C.
• Remote mounting: Remote installation is limited to 20 feet unless Universal approves another configuration.
• Cross-references: Do not substitute GE, Philips Advance, Sylvania, Keystone, Hatch, or Robertson models solely by published cross-reference; verify lamp operation, ballast factor, dimensions, lead layout, and switching functions.

Safety and Installation Guidelines

• The ballast must be grounded.
• Disconnect branch-circuit power before inspecting, wiring, installing, or removing the ballast.
• Follow the Universal wiring diagram for the exact lamp family and lamp-count configuration.
• Do not connect unsupported lamp types or lamp quantities.
• Use listed connectors and wire methods that comply with the National Electrical Code and local requirements.
• Cap all unused leads individually as directed by the manufacturer.
• Maintain proper fixture ventilation and do not exceed the 90°C maximum case temperature.
• Use only approved switches, occupancy sensors, relays, or control devices for the SW lamp-switching circuit.
• Do not install a ballast that shows physical damage, overheating, or damaged leads.
• Professional installation by qualified electrical personnel is recommended.
