HED SERIES - DUAL OUTPUT, 30 WATT
DESCRIPTION
HED dual output DC/DC converters are fully isolated
converters featuring high efficiency topology. The
HED has fixed frequency design with excellent
transient response and predictable EMI performance.
The HED uses planar magnetics, and has open-frame
packaging, 1500 VDC isolation, and an MTBF of over
one million hours. HED’s have overcurrent and
overvoltage protection, as well as input undervoltage
lockout.

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.
