Ballast/Driver Osram QTP5 2X49, AC 198–264 V, 50/60 Hz, lifetime 100000 h, -20–50 °C, 30×360×21 mm

Osram QTP5 2X49 is an electronic ballast/driver designed for fluorescent lighting systems that require stable operation across a wide input voltage range. The unit accepts AC input from 198 to 264 V at 50/60 Hz and is specified for a rated lifetime of 100000 hours. With an operating temperature range from −20 to 50 °C and compact dimensions of 30 × 360 × 21 mm, this ballast is suitable for both retrofit and new installations where space is limited and long-term reliability is important.

Advantages

The ballast provides consistent lamp starting and stable current control to ensure uniform light output and extend lamp life. Its wide input voltage tolerance and dual-frequency compatibility allow reliable performance in varying supply conditions. The compact form factor supports installation in confined fixtures and simplifies replacement of older magnetic ballasts. Specified for a long operational lifetime and low ambient temperature operation, the unit reduces maintenance frequency in commercial and industrial applications.

Suitable for

• Retrofit replacement of older electronic or magnetic ballasts in linear fluorescent fixtures
• New installations in offices, retail spaces, warehouses, and utility areas
• Applications requiring long-life operation and reduced maintenance intervals
• Fixtures with limited installation depth where compact ballast dimensions are needed

How to use

Install the ballast in accordance with local wiring regulations and fixture manufacturer instructions. Ensure power is disconnected before starting work. Mount the unit into the allotted space inside the fixture, connect the mains input to the AC supply terminals and wire the lamp outputs to the fluorescent tubes following the provided wiring diagram or standard wiring practice for 2x49 W lamps. Verify secure mechanical fixation and that the ambient temperature of the installation site is within the specified −20 to 50 °C range. After wiring, restore power and confirm correct lamp ignition and steady operation.

Usage recommendations

For optimal reliability, use the ballast with compatible linear fluorescent tubes rated for electronic operation and maintain adequate ventilation around the unit. Periodically inspect connections for corrosion or looseness and avoid mounting the ballast directly on surfaces exposed to excessive heat or moisture.
