Input Fuse 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 Conquer 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 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. With - / + 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. Power start Inrush current limit Normal current
Hold-up Time D type is in compliance with S2 level (10ms), while A types 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 their output load to, C types require de-rating their output load to, please refer to the curve diagrams below.
