DC to DC Converters

Distributed Power Supplies for Systems, Insulation Type

CF Series CFP10W/CFR15W/CFT30W Types

FEATURES

• This is an insulated onboard type product delivering among the

best efficiency in the industry.

This product delivers an efficiency of 91% (30W products) owing

to our unique synchronous rectification circuitry.

• This is an SMD onboard type, offering the lowest height profiles

in the industry. By optimizing mounting methods, we have been

able to achieve a thickness of only 4.0mm (10W).

• Wide operating temperature range from –40 to +85°C with natu-

ral air cooling (No derating).

• Wide input voltage range (DC.36 to 75V)

• Parallel operation is possible.

• Remote ON-OFF function.

• Various protective functions(output overvoltage protection,

output overcurrent protection and output undervoltage

protection)

• Alarm signal output function.

• It is lead-free compatible.

• It is a product conforming to RoHS directive.
