This Power supply is specially designed for access control system, and its main fuction as following:
When AC power supply is available, the electric pressure of the load is supplied by AC power.When AC power supply is unavailable, the electric pressure is supplied by battery.When the electric pressure of the battery drops to about 10V, the battery stops the supply to the load and it must be started again by AC power.Inside the UPS, there is an electric discharge protection circuit of the battery; the electric discharge quantity is set within the allowance range of the battery in order to prolong the working life of the battery.This power supply has protective functions of over-current, over-voltage and short circuit, it aslo enjoys the advantages of wide input range, stable output voltage and low pressure drop of the load.
