Product Overview

The Universal B228PUNVSV3-D is a high-performance electronic dimming ballast designed for (1-2) F28T5 fluorescent lamps. Featuring 0-10V dimming control from 100% down to 3% light output, this ballast provides smooth, flicker-free dimming for commercial lighting applications requiring precise light level adjustment.

With programmed start technology, the B228PUNVSV3-D extends lamp life by preheating cathodes before ignition – ideal for applications with frequent switching. The ballast includes built-in line voltage protection for the control circuit, preventing damage if line voltage is accidentally applied to control leads. Class A sound rating ensures quiet operation in noise-sensitive environments like offices and schools.

Compatibility & Replacement

Fixture type: This ballast is designed for T5 fluorescent fixtures using (1-2) F28T5 lamps. Compatible with F28T5/Alto, FP28/ECO, HE 28W/T5, and F28WT5/ECO lamp types.

Dimming control: 0-10V dimming system. 10V = maximum output, 0V = minimum output (3%). Ballast sources maximum 250µA for control needs. Can be wired as Class 1 or Class 2 circuit.

Protection features: Built-in line voltage protection prevents ballast damage if line voltage is accidentally applied to control leads. Deep-dimming condition protection when line voltage is applied to control leads.

Before ordering, confirm:

• Lamp type: Verify your fixture uses F28T5 lamps (1 or 2 lamps per ballast).
• Input voltage: Verify supply voltage is 120–277V, 50/60Hz.
• Dimming system: Confirm your dimming controller supports 0-10V output (10V = max, 0V = min).
• Physical dimensions: Verify your fixture has adequate space for a ballast of 16.88" L x 1.18" W x 1.00" H.
• Temperature rating: Ensure fixture environment does not exceed 167°F (75°C) case temperature.
• Minimum starting temperature: Confirm ambient temperature is at least 50°F (10°C) for reliable starting.
