InputFuse
There is a fuse connected in series to the positive input line, which is used to protect against abnormal surge. Fuse specifications of each model are shown as below.

Type	Fuse Type	Reference and Rating
A	Time-Lag	Conquer MST, 10A, 250V *2
B	Time-Lag	Conquer MST, 8A, 250V *2
c	Time-Lag	Conguer MST, 8A, 250V *1
D	Time-Lag	Conquer MST, 4A, 250V *1

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.Input Reverse Polarity Protection
Thereis aMOSFET connected in series to the negative inputline. If the input polarity is connected reversely, the MOSFET opens and there will be no output to protect the unit.
InputRange and Transient Ability
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.Hold-up Time
EN50155: 2007 version -D type is in compliance with S2 level (10ms), while Atypes are in compliance with S1 level (3ms) at full load output condition. To fulfil the requirements of S2 level (10ms), B types require de-rating theiroutput load to 70%, C types
require de-rating their output load to 60%, please refer to the curve diagrams below.Efficiency vs Load & Vin Curve
The efficiency vs load & Vin curves of each model are shown as below.
