Note :
1.The suffix "*" is part of the model number, which specifies the product is designed and pre-trim for low-cost DC backup power system with
external Lead-Acid battery, Relay and Fuse.
2.The manufacturer is liable neither for the external components nor the damage to the power supply causing by external components.
3.The total consumption current including loading and battery charging current should not exceed the maximum rated current of power supply.
4.The operation concept of DC backup power system :
A. When AC power alive : The "Rdy" is close circuit to active the external Relay . The power supply feeds current into the external loads and
charges through Relay to the external battery as well.
B. When AC power interrupted : The "Rdy" is remain close circuit to maintain the external Relay remain active, the external battery supply
current to the external loads.
C. When Battery power low : The "Rdy" become open circuit and the external Relay become inactive to disconnect the battery from
external loads.
