SMPS1260 is an input voltage of 100-240V, outputcurrent 12VDC/6A Switching Power Supply, input with a reliable anti-surge, lightning, overcurrent protection circuit; 12VDC including 5 groups output, each group comes with self-recovery insurance, can guarantee a reliable running when one group encounter overcurrent or short circuit, overcurrent fault, does not affect other group output; and extra group is 13.8V/300mA battery float voltage output for maximum battery backup 12V/7AH charge; city power and battery backup is seamless handover, ensuring the system can continue to use simultaneously when city power cut off. At the same time, provide a reliable power supply protection circuit to prevent batterydischarge, when the backup battery voltage is lower than 10.8V, output will cut off automatically.
