TECHNICAL SPECIFICATIONS
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.
