Product Description

1 INTRODUCTION
1 , GPAD351M27-5A is a high-duty power supply with AC/DC multi-outputs. Thanks for the latest circuit design, it is compact and of reliable performance. It has the wide range of input voltage and has many functions including short-circuit protection, over-current protection and lightningproof function, accumulator charge. The cooling way is natural conductive. The power supply is designed strictly in accordance with the safety regulations, which conforms to the safety standards and requirements of information technology.
2 , When the AC power is off, it can switch over and supply power by the main battery automatically (six outputs). If the main battery discharge when being insufficient to get voltage, it can automatic protection and stop discharging . And then i t switch over and supply power by the lithium ionic battery , and now it has tri-outputs(+5V, +12V), If the lithium ionic battery discharge when being insufficient to get voltage , it can automatic stop discharging .
