Function Manual
1. Current sharing (1) Parallel operation is available by connecting the units shown as below (P+,P- are connected mutually in parallel) : (2) The voltage difference among each output should be minimized that less than 0.2V is required. (3) The total output current must not exceed the value determined by the following equation (Output current at parallel operation) =(The rated current per unit) x (Number of unit) x 0.9. (4) In parallel operation 4 units is the maximum, please consult the manufacture for other applications. (5) When in parallel operation, the minimum output load should be greater than 3% of total output load. (Min. load > 3% rated current per unit x number of unit)

Input Reverse Polarity Protection
There are two MOSFETs connected in series to the negative input line. If the input polarity is connected reversely, the MOSFETs open and there will be no output to protect the unit.
Inrush Current
Inrush current is suppressed by a resistor during the initial start-up, and then the resistor is bypassed by MOSFETs to reduce power consumption after accomplishing the start-up.
Inrush current limit Power start Normal current
