The positive electrode has a high electric potential and the negative electrode has a low electric potential. The DC backup power supply has two electrodes, a positive electrode, and a negative electrode. With multi-level lightning protection measures, the system has strong impact resistance, fast dynamic response, and complete system schemes, which can be widely used in various communication equipment. It is with fully automatic current sharing N+1 redundant modular design and the monitoring system realizes intelligent real-time supervision of the rectifier module, feeder input, and battery. The power system is designed for the requirements of the communication industry, adopts international advanced high-frequency phase shift edge resonance technology, and ultra-wide-range AC input, and the module adopts power factor correction technology, which is efficient, and reliable. The power system provides various high and low-frequency AC and DC backup power supplies for various motors to maintain the smooth operation of the motor system. The Power System is composed of rectifier equipment, DC power distribution equipment, battery packs, DC converters, rack power equipment, and related power distribution lines. The backup power supply continues to supply power to the load when there is no grid power supply.Īpplication of Rechargeable Battery Backup Power Supply In an emergency, the switch cuts off the connection between the backup power supply and the grid.Ĭ.
In non-emergency situations, the power grid charges the backup power supply, and the backup supply source also supplies power to the load.ī. UPS is only suitable for capacitive loads, so it is commonly used in computers and other fields and is often used as a rechargeable backup power supply for an office.Ī. UPS backup power supply consists of a transformer, charger, storage battery, etc. When the main power supply returns to normal, the dual power supply switch will instantly switch back to the main power supply. In an emergency, the dual power supply switch switches the load from the main power supply to the backup power supply in a very short time (with a millisecond level).Īt this time, the main power supply is off, and the backup power supply provides power to the load. In non-emergency situations, the main power supply is in working condition, and the backup power supply charges the power supply battery through the charging device. Therefore, EPS is commonly used in fire fighting and other fields, and it is also a better battery rechargeable battery backup for home.ĮPS rechargeable battery power supply working principle: EPS emergency power supply is suitable for inductive loads (such as gas discharge lamps, fluorescent lamps, and motors) and resistive loads (such as incandescent lamps). Nowadays, most people choose to use EPS backup power supply and UPS backup power supply:ĮPS backup power supply is composed of an inverter, rectifier, charger, battery, isolation transformer, controller, switch, and so on. The rechargeable backup power supply is commonly used in industries, commerce, and fire protection. Nowadays, lithium-ion backup power is getting more popular.
EMERGENCY BATTERY BACKUP FOR HOME GENERATOR
The battery-type backup power supply unit components of chargers, inverters, batteries, dual power switches, etc., and the generator-type backup power supply unit components of generator sets, isolation transformers, and dual power switches. The different power sources can be divided into battery-type backup power and generator-type backup power. It is a device that replaces the main power supply to supply power to the load when the main power supply fails to work normally in an emergency. The backup power supply is also called an emergency power supply.
