New EPS emergency power supply performance standard

1, emergency lighting centralized EPS emergency power supply should be set with main power, charging, fault and emergency state indicator light, main power state with green, fault state with yellow, charging state and emergency state with red.

2, emergency lighting centralized EPS power supply should be set up to simulate the main power supply failure of the self-compound test button (or closed), should not affect the emergency function of the switch.

3, emergency lighting concentrated EPS power supply should display the main voltage, battery voltage, output voltage and output current.

4, emergency lighting centralized EPS power supply main power and backup power should not be output at the same time, and can be manually and automatically transferred to the emergency state, and should be set up only professionals can operate the mandatory emergency start button, after the button is started, the emergency lighting centralized power should not be affected by discharge protection.

5. Each output branch of the EPS power supply for emergency lighting should be protected separately, and the failure of any branch should not affect the normal operation of other branches.

6, emergency lighting concentrated EPS power supply should be able to work normally under no-load, full load 10% and overload 20% conditions, output characteristics should meet the manufacturer's regulations.

7, when the rated voltage of the serial battery pack is greater than or equal to 12V, the emergency lighting centralized power supply should be protected by the battery pack, each section of the battery (group) rated voltage should not be greater than 12V, and when the battery (group) is fully charged, each section of the battery (group) voltage should not be less than the rated voltage. When any section of the battery voltage is less than the rated voltage, the emergency lighting centralized power supply should emit a fault sound, light signal and indicate the corresponding part.

8, emergency lighting concentrated EPS power supply in the following circumstances should issue a fault acoustic, optical signal, and indicate the type of fault; The fault sound signal should be manually eliminated, and when there is a new fault signal, the fault sound signal should be restarted; The faulty optical signal should be maintained until the fault is rectified.
