What is EPS fire emergency power supply?

The EPS fire emergency power supply is a standby AC power supply device that controls the high-power conversion with weak current, and belongs to the power electronic equipment. EPS fire emergency power supply is mainly used for electrical equipment in the fire protection industry, mainly for emergency power supply after the mains power failure. It mainly provides emergency backup power for fire emergency lighting and fire power of various buildings and important public facilities, and also has many applications in industrial fields such as chemical, metallurgy, sewage treatment and automated production lines.

What is the characteristic of EPS fire emergency power supply?

    1. The rated inverter power of the EPS fire emergency power supply shall not be less than the maximum power of the single motor and equipment or the group of motors and equipment. For the DC output, the on-site inverter EPS emergency power supply, the reverse should be considered. Change the busbar voltage drop.

  2. The ups battery capacity of EPS fire emergency power supply should ensure the requirements of emergency working time after the load is stable.

    3. Fire-fighting special EPS fire emergency power supply can be used as the backup power ups supply for the fire automatic alarm system. It supplies power to the equipment or related facilities (locations) in the system. The EPS fire emergency power supply for the fire-fighting equipment cannot supply power for emergency lighting at the same time. .

    4. When the EPS fire emergency power supply is used for power supply of single-phase no break ups power supply with rated power less than 30KW and three-phase power supply rated power less than 120KW, the following methods shall be adopted:

    1) EPS fire emergency power supply for AC output, one EPS fire emergency power supply can supply power for one equipment or multiple fire protection equipment for mutual investment;

    2) DC output, on-site inverter EPS fire emergency power supply, can be used for trunking or radial distribution with multi-inverter/frequency conversion extension for one equipment or multiple fire-fighting equipment for mutual investment.

    5. The EPS fire emergency power supply for the single-phase power supply rated power greater than 30KW and the three-phase power supply rated power greater than 120KW shall not supply power to other loads at the same time.

    6. When there is elevator load, the voltage of the EPS fire emergency power supply inverter busbar should not be lower than 80% of the rated voltage according to the most unfavorable full load at the same time. When there is no elevator load, the bus voltage of the EPS fire emergency power supply It should not be less than 75% of the rated voltage.

It is widely applicant for the emergency lighting system, what is more important, compared to the double conversion online ups, the EPS fire emergency power supply is energy saving and higher efficiency.
