Luso Electronics has recently rolled out the latest AC-DC power supply family from N2Power. The XL375LED is a constant current 375W AC-DC power supply designed to drive strings of LEDs in high-power lamps for industrial, entertainment and outdoor lighting applications.

Many LED lighting and display applications require constant current output and also need to be shielded from power disturbances. The XL375LED covers all these requirements, combining ruggedized design, high efficiency and reliability. The device's high efficiency, up to 93 per cent, supports the lighting industry's drive to reduce energy consumption through the use of solid-state LED light sources. Expected key markets for the products are architectural lighting; warehousing and retail environments for both high- and low-bay lighting; and in the entertainment arena for concert venues and stage/theatre lighting.

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 8.38 x 12.7cm, delivering a power density of more than 15W/in3. Other features of the XL375LED include active power factor correction, current sharing and inrush current protection.

The XL375LED also has a universal AC input (90-305VAC), which is particularly important for LED lighting manufacturers to achieve 277VAC input certification.

The unit is RoHS compliant and meets all major international safety and EMC requirements.

Sample units are now available from Luso for the development of new lighting system designs.
