Datasheet - LPD300 Series

The LPD300 is a series of Audio/Video IT/Industrial grade power supplies designed to offer the high-power density and high efficiency that space constrained and power demanding systems need. Available in 12, 24, and 48 VDC outputs, the series provides up to 300 W steady output power with moving air, or from 190 W upwards with convection cooling over the 110 – 240 VAC nominal input voltage range, all in a compact 2.28 x 4.09 x 1.00” form factor package.

The semi-potted base-plate package allows thermal management through conduction cooling particularly needed in those installations where the heat can be dispelled solely through solid thermal path.

The series also includes 15, 28, 30, 36 and 54V versions whose availability will be assessed upon demand.
With 94% typical efficiency and extremely low (< 0.3 W) power consumption at no-load, the LPD300 facilitates thermal management and equipment design, including compatibility with the latest environmental legislations. The LPD300 series meets all EMC newest standards for emissions and immunity.

The series comes configured in the IEC protective Class I.
