UPS is an uninterruptible power supply. It is usually one of the engineering subsystems of the weak current room. It connects the battery to the host equipment and provides stable and uninterrupted power supply for the equipment. An ENERGY CONVERSION DEVICE THAT USES battery chemical ENERGY as BACKUP ENERGY TO continuously provide (AC) electrical energy to user equipment during grid failures such as mains outages.
How is the UPS power supply equipment composed?
◆1.Rectifier, single phase or three phase AC mains by matching the isolation transformer input rectifier, when the city voltage in ± when the load in the range of 100% changes, the output DC voltage of the rectifier is stable in 15%±1%.
◆2.The inverter uses high-frequency carrier sinusoidal pulse width modulation technology igbt inverter module to convert DC voltage into standard sine wave AC voltage, and provides stable voltage to AC load equipment after output isolation. High quality power supply with stable frequency.
◆3.Battery, when the municipal voltage undervoltage or fault, and DC end connected to the battery will automatically provide uninterrupted power. When the DC screen discharges, it emits a signal. If the discharge reaches the limit voltage, the system will be transferred to the backup power supply. When the termination discharge voltage is approaching, the system will issue a warning signal. When the municipal power supply or backup power supply uses a dual AC model, it will be converted to battery power when both AC inputs fail.
◆4.Static switch can continuously complete bypass and inverter switch function, can be completed automatically or manually.
◆5. Intelligent monitoring through 232/485. Passive contact for intelligent monitoring. Power transmitter will be ups real-time transmission of working status and data dcs to achieve intelligent monitoring system.
