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 100°C, 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. Please see the IAD series for dual-output
applications.

Notes
MTBF predictions may vary slightly from model to model.
Specifications typically at 25°C, normal line, and full load, unless otherwise
stated.
Soldering Conditions: I/O pins, 260
°C, ten seconds; fully compatible with
commercial wave-soldering equipment.
Safety: Agency approvals may vary from model to model. Please consult factory
for specific model information.
Units are water-washable and fully compatible with commercial spray or
immersion post wave-solder washing equipment.
