LES SERIES - 15 WATT
DESCRIPTION
LES DC/DC converters provide up to 15 Watts of output power in an industry standard package and footprint. With a maximum case temperature of 100C, the LES is well suited for the most demanding telecom, networking, and industrial applications. The LES features 1500 VDC isolation, short circuit, and overtemperature protection, as well as six-sided shielding. The LES is available with optional enable and voltage trim pins. Please see the IAD Series for dual output applications.
