Advantages of emergency power supply as backup power supply

EPS emergency power supply is a high-tech, environmentally friendly product that applies inverter technology and adopts CPU control, digital circuits, and highly integrated electronic components. It is mainly composed of inverter, auxiliary power supply, rectifier charger, battery, controller, etc. , providing second or third power supply for primary and secondary loads and particularly important electrical equipment, fire-fighting facilities, emergency lighting, etc. EPS is simple to maintain, can be unattended, can be linked to fire protection, operates automatically, and can also realize remote or building intelligent monitoring. Its start-up time is 0.1S, which is much shorter than the start-up time of diesel generator sets. The total investment is similar to diesel generator sets.

The general working principle of EPS emergency power supply: When the mains input is normal, the normally open contact of the relay is closed, and the mains intelligently charges the battery through the charger. When the mains power is interrupted or abnormal, the controller starts the frequency converter or inverter, and at the same time controls the normally open contact of the relay to close, and the battery's DC is converted into AC power by the frequency converter or inverter to supply the load. This machine adopts IGBT devices and SPWM inverter technology and advanced intelligent CPU control. It has a simple structure and reliable performance. It has a sine wave stabilized voltage and frequency output, automatic switching, and can be linked to fire protection. It is mainly suitable for evacuation lighting, accident lighting, water pumps, and fans. wait. Our company provides emergency power supply with centralized power supply. The installation methods can be divided into hanging type, embedded type and floor type. The emergency time is generally 90 minutes.

EPS emergency power supply has many specifications. According to the input mode, it can be divided into single-phase 220V and three-phase 380V. According to the output mode, it can be divided into single-phase, three-phase and single- and three-phase mixed output. The installation forms include floor-standing, wall-mounted and wall-embedded. Three types; capacity ranges from 0.5KW to 800KW; according to service objects, it can be divided into two types: power load and emergency lighting; its backup time is generally 90-120 minutes, if there are special requirements, the backup time can be configured according to the design requirements . Therefore, EPS emergency power supply can meet the needs of general projects.

There are many issues to consider when using a diesel generator . When designing a diesel generator room, a series of issues need to be considered: the size of the diesel generator room, the transportation channels of the unit, the settings of the air inlet and exhaust vents and flues. In addition, an environmental protection company must be asked to carry out special inspections of the diesel generator room. Environmentally friendly design to ensure that the noise and smoke emissions meet the requirements. And when doing fire protection design, because of the existence of diesel generator sets, a CO2 gas fire extinguishing system must be added. Therefore, every time when designing a diesel generator set, repeated coordination must be carried out to consider both the beauty of the building and the operation requirements of the diesel generator set.
