LES SERIES - 15 WATT
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 100°C, the LES is well suited for the most
demanding telecom, networking, and industrial applications. The
LES features 1500VDC isolation, short circuit, and over-
temperature 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.
