110W isolated DC/DC converter with 11.7 CFM forced air-cooling, 70W convection cooled
Fully isolated primary and secondary
Wide input range 9-32VDC
Compact size 2 x 5 inch
Low inrush current to prevent power adapter turn on issue
Input polarity reversed protection
Built in DC input on/off switch controller
High efficiency up to 88% 1. Description The MPD-F113-1 is a 110W single output DC/DC converter. It is a compact size 2 x 5’’ and wide input range from 9-32VDC. Fully isolated primary to secondary avoid disturbed noise to affect secondary side. The low inrush current is 3A max. for preventing turn on issue and protecting the power supply. The built in DC input on/off switch controller can use with a normal on/off switch, instead of high rated current switch, and TTL signal control is available as well (see 8. application note). In addition, design in polarity reverse protection to avoid wrong input polarity. Output Min.

Interface Signals and Internal Protection Parameter Conditions/Description Short Circuit or Over The power supply will go into hiccup mode against short circuit or over load conditions, Load Protection and will auto-recovery while fault conditions moved. Input On/Off switch (1) Use a switch to short pin1 and pin2 of SW1 to turn on the power supply. (2) Or, it can use TTL signal to control the power on/off (please see more detail at Application Note). Over Voltage Protection For some reason the power supply fails to control itself, the build-in over voltage protection circuit will shut down the outputs to prevent damaging external circuits. The trigger point is from 12.8V to 15V. 5. Safety Approvals, EMI and EMS Specification Parameter Conditions/Description Min. Nom. Max.
