Philips Elettronic Ballast 28/35/49/80W TL5 EII T5

Philips Electronic Ballast HF-Pi 28/35/49/80W TL5 EII T5 is an electronic ballast manufactured by Philips for neon discharge fluorescent lamps of the T5 type, product reference 9137006526. Built in metal with compact dimensions of 425 x 30 x 22 mm, this ballast is capable of powering 2 light sources simultaneously, managing lamp wattages ranging from 2x28W to 2x54W. It operates on alternating current at 220-240 V, with a protection rating of IP20, making it suitable for indoor installation.

One of the most distinctive features of this ballast is its automatic lamp recognition capability: the unit independently adapts its operating parameters to match the specific lamp connected, with no manual adjustment required. This provides a significant practical advantage when working with TL5 lamps, as it allows TL5 HE and TL5 HO tubes of the same length to be interchanged without any modification, greatly simplifying maintenance and replacement management. The ballast features a 7-connection output, offering installation flexibility and compatibility with a wide range of wiring configurations. It is designed primarily for indoor use; if installed in exposed environments, the host luminaire must provide adequate protection against water, dust and atmospheric discharges, in compliance with applicable installation standards.
