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.
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 protection, and six-sided shielding.
The LES is available with optional enable and voltage trim
pins.
Please see the IAD Series for dual output
applications.
