Input Reverse Polarity Protection
RSD-300
series
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.
Input Range and Transient Ability
The series has a wide range input capability. Within
±
30% of rated input voltage, it can be executed at full-load operation and operate properly; with
±
40% of rated input
voltage, it can withstand that for 1 second.
Input Under-Voltage Protection
If input voltage drops below Vimin, the internal control IC shuts down and there is no output voltage. It recovers automatically when input voltage reaches above Vimin,
please refer to the cruve below.

Inrush Current
Inrush current is suppressed by a resistor during the initial start-up, and then the resistor is bypassed by a MOSFET to reduce power consumption after accomplishing
the start-up.
Hold-up Time
D and F and E-5 types are in compliance with S2 level, while B and C and E types are in compliance with S1 level at full load output condition.
To fulfil the requirements of S2 level, B and C and E types require de-rating their output load to 70%, please refer to the curve diagrams below.
