They feature: -
- Lightweight and Small Size: Switching mode power supply has the advantages of lightweight and small size. Comparing wth linear mode power with the same power output, it is much lighter and smaller.
- High Efficiency: The units operate with an efficiency over 80% under the best conditions.
- Overload Protection: The current foldback circuitry is adopted to prevent overload. An indicator will show if a unit is overloaded.
- Over Temperature Protection: The over temperature circuitry is functioned when the unit is over a certain high temperature to prevent a unit from damage by the high temperature. When the circuitry is functioned, the output voltage and current will drop down to a safety value an the overloaded indicator will light up.
- Over Voltage Protection: The over voltage circuitry will protect the unit and the laoding equipment from damage by abnormal high output voltage.
- High RFI Stability: The high protection circuitry against RFI (Radio Frequency Interference) provides a stable operation.
- Variable Voltage Output: The variable range of output voltages from 3V to 15V enables good fits with variable uses.
