120W DIN Rail Type DC ~~-~~ DC Converter 

D D R ~~-~~ 1 2 0 series 

## Hi Input Reverse Polarity Protection 

There is a MOSFET connected in series to the negative input line. If the input polarity is connected reversely, the MOSFET opens and there will be no output to protect the unit. 

## Bi Input Range and Transient Ability 

The series has a wide range input capability. With ~~-~~ 30% / +40% of rated input voltage(exceptA Type), it can withstand that for 1 second. 

## Bi Inrush Current 

Inrush current is suppressed by a current limit circuit during the initial start ~~-~~ up, and then the circuit is bypassed by a MOSFETto reduce power consumption after accomplishing the start ~~-~~ up.
