Meanwell LPF-40

A Power supply of Meanwell LPF-40 has a 40W dual mode constant voltage and a constant current output, as well as an integrated active PFC function. The power supply operate with input voltage 90 to 305 V AC, there are models with different nominal voltage from 12V to 54V. The power supply operates as a constant voltage power supply until reaching the maximum charges, and switch then into the contant current range. Protective circuits avoid damage to the power supply and the load.
The product offers excellent energy saving possibilities thanks to its high efficiency and low power dissipation, thus enabling compliance with the latest international lighting regulations.

Due to the rugged design and high protection against dust and moisture, it can be used in many indoor and outdoor LED applications.
This LED power supply provides a constant current, constant voltage or a combination of constant voltage and current with fixed or adjustable values.

Thus, the Meanwell LPF-40 LED switching power supply is ideal e.g. in version -12 for the operation of 12V lamps, such as low-voltage LED spotlights MR16 / GU5.3 or MR11, as well as LED stripes. Up to a power of 40W, several lamps can be connected to a single transformer. Cost savings!

LPF-40 Features (type dependent):

  • 5 years manufacturer guarantee
  • Type LPF for use according to Class II
  • Universal AC input up to 305V AC
  • Overload protection by current limiting, auto recovery
  • Integrated PFC circuit
  • Low idle power
  • Plastic housing
  • Self Cooling by free air convection (temperature protection)
  • Protection against short circuit, overvoltage and overload (temperature protection)
  • IP30 protection
  • LED lighting, especially street lighting

Meanwell LPF power supplies are also available as a LPF-40D variant. This power supply is distinguished by its 3 in 1 dimming function (external voltage 1 to 10 Volt DC, PWM, potentiometer).
