Input Reverse Polarity Protection
Input Range and Transient Ability
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.
The series has a wide range input capability. With -30% / +40% of rated input voltage(except A Type), it can withstand that for 1 second.
Inrush Current
Inrush current is suppressed by a current limit circuit during the initial start-up, and then the circuit is bypassed by a MOSFET to
reduce power consumption after accomplishing the start-up.
