Keystone Technologies kteb-432-uv-is-n-p-dp F32T8 Ballast

Product Description

The KEYSTONE TECHNOLOGIES kteb-432-uv-is-n-p-dp is a 4-lamp, instant-start electronic ballast designed for F32T8 fluorescent lamps operating on 120 to 277 volts. With a ballast factor of 0.88, it delivers slightly reduced light output compared to a standard 1.0 BF ballast, making it a practical choice for energy-saving lighting retrofits and new installations where modest lumen reduction is acceptable. The ballast is non-dimmable and suited for commercial and light industrial fluorescent fixture applications. Licensed electricians and lighting maintenance technicians handle installation in standard troffer and strip fixtures.

This ballast is intended for use with four F32T8 (32-watt, T8) fluorescent lamps in commercial office, retail, warehouse, and institutional lighting systems. Its wide voltage range of 120 to 277 volts allows deployment across single- and multi-phase electrical systems without requiring separate voltage-specific SKUs. Instant-start operation eliminates lamp preheating, which reduces lamp strike time and simplifies fixture wiring compared to programmed-start designs.

Key Features

• Drives four F32T8 fluorescent lamps from a single ballast
• Wide input voltage range: 120 to 277 volts for flexible installation across electrical systems
• 0.88 ballast factor provides measurable energy reduction versus standard-output ballasts
• Instant-start operation for fast lamp strike and simplified wiring
• Non-dimmable — compatible with standard on/off switching only
• Compact form factor fits standard fluorescent fixture housings

Compatibility

Designed as an OEM-style replacement or new-installation ballast for four-lamp F32T8 fluorescent fixtures operating on 120 to 277 volt circuits.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Disconnect and lock out power to the fixture at the circuit breaker before removing the old ballast or making any wiring connections. This ballast is non-dimmable and must not be connected to dimming controls or occupancy-sensor circuits that apply reduced voltage, as doing so can damage the ballast and void any applicable listing. Verify lamp count and lamp type (F32T8) match the ballast rating before energizing the fixture.
