The new SLP420 AC-DC power supply is a highly efficient (94%), compact solution with high input-to-output isolation to meet SELV requirements. Designed for IT/Industrial, LED video wall displays and LED lighting applications, it provides 420 W of regulated DC power through the full 100 – 277 VAC nominal input voltage range. Available in an open frame 3.0 x 5.0 x 1.5” form factor, the SLP420 provides a nominal 48 VDC regulated output voltage which can be manually adjusted up to 51 VDC.

The SLP420 is capable of a steady 330 W of power in free air cooling, and 420 W with forced air cooling. It can operate up to 80ºC with de-rating, and is capable of -30ºC start-up. The series complies with the 2nd edition of the IEC/UL60950-1 standard for IT equipment, and UL8750 for LED lighting applications. The series meets the EN55032 EMC limits of Class B for conducted emissions, as well as EN55024 for immunity. It complies with IEC/EN61000- 3-3 limits for voltage fluctuations/flicker and IEC/EN61000-3-2 Class C for harmonic content.
