SMPS (SMPS-01)
This product is a 12V SMPS power supply for low power CDMA FWTs & similar systems. It contains a 12V7AH sealed Lead-acid battery (which can be modified via needs) and provides a DC output of 12V1. 4A (which can be modified via needs). It uses the switching power source as the charger, which is excellent in capability and has high source transition efficiency that is above 75 percents. It also contains functions as followings: Protection against over-voltage and over-current: AC input voltage should be between 90V and 300V. But even if AC input voltage rises to 450V or above, the equipment would not be burned out.Protection against lightning, surge and interference.Alarm and protection taking place when the battery is in low-voltage.Protection against system invalidation.Protection against reverse connection of battery.Constant current-charging techniques for extending the life-span of battery.When the mains electricity input cuts off, the battery takes the load instantly, without any interruption to the load.This product is an excellent equipment for uninterrupted power suppling. Besides, if changed the battery or modified parts of its design, it will provide far more kinds of voltage and current output while maintaining its excellent capacity, adapted to all kinds of small power electronic equipment.
