EPS emergency power performance new standards!

The emergency lighting centralized EPS emergency power supply shall be provided with main power, charging, fault and emergency status indicators. The main power status is green, the fault status is yellow, and the charging status and emergency status are in red.

 

1. The emergency lighting centralized EPS emergency power supply shall be provided with main power, charging, fault and emergency status indicators. The main power status is green, the fault status is yellow, and the charging status and emergency status are in red.

The

2. The emergency lighting centralized EPS power supply shall be equipped with a self-rebuilding test button (or switch) that simulates the main power supply failure, and shall not have a switch that affects the emergency function.

The

3. The emergency lighting centralized EPS power supply shall show the main voltage, battery voltage, output voltage and output current.

The

4. The emergency lighting centralized EPS power supply main power and standby power should not be output at the same time, and can be manually or automatically transferred to emergency status, and a mandatory emergency start button that can only be operated by professional personnel should be set. After the button is activated, Emergency lighting centralized power supply should not be affected by over-discharge protection.

The

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

The

6. The emergency lighting centralized EPS power supply should be able to work normally under conditions of no load, full load 10% and overload 20%, and the output characteristics should comply with the manufacturer's regulations.

The

7. When the rated voltage of the tandem battery pack is greater than or equal to 12V, the emergency lighting centralized power supply shall protect the battery component segments. The rated voltage of each battery (group) shall not exceed 12V, and when the battery (group) is fully charged, each segment The battery (group) voltage should not be less than the rated voltage. When any of the battery voltages is less than the rated voltage, the emergency lighting centralized power supply shall issue a fault sound and light signal and indicate the corresponding location.

The

8. The emergency lighting centralized EPS power supply shall emit fault sound and light signals and indicate the type of fault under the following conditions; the fault sound signal shall be able to be manually eliminated; when there is a new fault signal, the fault sound signal shall be restarted; fault light The signal should be maintained before troubleshooting.

The

The fault conditions are as follows: a) The connection line between the charger and the battery is open; b) The emergency output circuit is open; c) In the emergency state, the battery voltage is lower than the overdischarge protection voltage value.
