375W constant current power supply for high power LED lamps

October 26, 2012 // By Julien Happich
The XL375LED 375W AC-DC power supply from N2Power is designed to drive strings of LEDs in high power lamps for industrial, entertainment and outdoor lighting requirements.

The XL375LED models offer single main outputs of 12, 24, 28, 36, 40, 48 or 56VDC maximum. They also have a 12V/1A auxiliary output (normally used to drive a cooling fan) and a 5V/1A standby output. The compact 3.81cm high package has a footprint of just 83.8x127mm and is up to 93% efficient. This high efficiency further supports the lighting industry's drive to reduce energy consumption through the use of solid-state LED light sources. Other features of the XL375LED include active power factor correction, current sharing and inrush current protection. The XL375LED has a universal AC input (90-305VAC), which is particularly important for LED lighting manufacturers as they need to achieve 277VAC input certification. The unit is RoHS compliant and meets all major international safety and EMC requirements.
