Powering Communications and Technology
IES SERIES
20 WATT
DESCRIPTION
IES DC/DC converters provide up to 20 Watts of
output power in an industry standard package. With
88% efficiency and a maximum case temperature of
100°C, the IES is well suited for the most demanding
telecom, networking, and industrial applications.
The IES features 1500 VDC isolation, short circuit,
and overtemperature protection.

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.
