Small switching supply meets RoHS, shock, EMC standards

( 01 Sep 2005 )

Designed for telecom, ATE, automation, and similar applications, the LPT18 power supply from Taiyo Yuden takes line-level ac and produces two dc outputs, with an overall rating in the 18W range. The 114mm long _ 32mm wide _28mm high unit accepts 100-240Vac (47-63Hz) and delivers +5.1Vdc/3A and -5Vdc/1.5A. A convection-cooled unit, it achieves efficiency up to 85% due to a discontinuous variable-frequency mode of switching operation.

This supply meets many difficult industry requirements, including full compliance with the European Union’s Restriction on Hazardous Substances (RoHS); EN61000-4-4 Level 3 surge withstand; MIL-STD- 810F shock and vibration; and FCC Part 15B and EN-61000 EMC standards. It is priced at $10 in OEM quantities.
