Philips Xitanium 80W 24V DC LED Power Supply – Constant Voltage, 120–240V AC, 50,000h Lifespan

Philips Xitanium LED Power Driver 80W 24V (model no. 929001669406) is a fully electronic constant-voltage power supply designed to power 24V DC LED strips and LED modules in indoor installations. It performs reliably wherever stable, consistent operation over many years is required – in refrigerated display cases and freezers, supermarket shelf lighting, signage backlighting, and linear lighting. The 120–240V AC input voltage and comprehensive global certification package (CE, UL, VDE, ENEC, CCC, CSA) make it a ready-to-deploy solution for European, American, and Asian markets.

Key Advantages

• SELV output voltage (UL Class 2): the 24V DC output voltage meets SELV safety requirements – even if wiring or the LED module is damaged, there is no risk of electrical shock to the end user.
• Stable 24V DC output voltage (load regulation ≤ 1%): consistent voltage level regardless of actual power consumption › uniform brightness and color temperature throughout the installation with no visible differences.
• Efficiency up to 88% (at 230V AC): lower heat losses result in reduced energy bills and lower cooling requirements for cabinets or fixtures.
• Wide input range 108–264V AC, 45–66 Hz: a single model operates correctly in both European (230V) and American (120V) mains, as well as with power network fluctuations in industrial environments – no need for separate versions.
• 50,000-hour lifespan: under continuous operation, this represents over 5 years without power supply replacement › significantly lower service costs for installations with difficult access (ceilings, refrigerated cabinet enclosures).
• Automatic restart after short-circuit, overload, and overheating: the power supply automatically resumes operation after a fault clears – no service intervention or power cycle required.
• Operating temperature from -30 to +60 °C: allows installation directly in the refrigerated zone of a display case or freezer without risk of damage during equipment shutdown.

FAQ – Frequently Asked Questions

Is this power supply suitable for 24V LED strips?

Yes. The power supply delivers stable 24V DC and handles loads from 2.4W to 80W – it is an ideal power source for 24V LED strips, LED modules, and light bars used in refrigerated display cases, supermarket shelves, and linear lighting applications.

Does the power supply work on both 230V and 120V networks?

Yes. The input range is 108–264V AC, allowing operation on both European 230V and American 120V networks – without any switches or modifications required.

Can the power supply be installed in the refrigerated zone of a display case?

Yes. The minimum ambient temperature is -30 °C, so the power supply can operate directly inside a refrigerated or freezer display case. The only requirement is that the housing temperature (Tcase) does not exceed 85 °C.

What happens if there is a short-circuit on the output?

The power supply enters hiccup mode (brief test pulses) and automatically resumes operation once the short-circuit clears. No manual restart or fuse replacement is needed.

What is the lifespan of the power supply?

The declared lifespan is 50,000 hours when the housing temperature (Tcase-life) does not exceed 75 °C. Under continuous operation, this represents over 5 years without replacement.

What is the IP protection class of the power supply?

The power supply has IP20 protection – it is designed exclusively for indoor installation. It cannot be exposed to moisture, snow, water, or direct contact with ice. Protection against external conditions is provided by the enclosure of the fixture or cabinet in which it is mounted.

What is the maximum cable length between the power supply and the LED module?

The maximum total cable length between the power supply and LED modules is 2.5 m. Exceeding this length may cause voltage drops and uneven lighting.
