HED SERIES - DUAL OUTPUT, 30 WATT
DESCRIPTION
FEATURES
HED dual output DC/DC converters are fully isolated • 30W Dual Output
• Planar Magnetics
• Output Trim
• 1500V Isolation
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.
• OVP and Short Circuit
Protection
• High Efficiency Topology • 100°C Baseplate
