DESCRIPTION
FEATURES
Efficiency vs. Load (24V Input)
IES SERIES
20 WATT
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.
