Using industrial frequency UPS power supply will greatly improve the safety and stability of load equipment. The components of the industrial frequency UPS power supply can be designed according to the customer's specifications and needs. Each component can withstand higher rated power and has a longer life span to ensure the safety and durability of the user's equipment operation process.
The industrial frequency UPS power supply is mainly designed to be used in harsh industrial environments, and the protection level has reached IP54. The industrial frequency UPS power supply is designed to work in an industrial environment and is used in various harsh industrial outdoor environments, and can adapt to high-temperature environments. 0~ 55℃, relative humidity 0%~95%, dustproof and rainproof.
The power frequency UPS power supply installs the isolation transformer at the output end, mainly to boost the output voltage with insufficient peak value to the output voltage with sufficient peak value. The isolation transformer realizes the function of electrical isolation and isolates the load from the power supply to prevent sudden situations from impacting the load.
The role of isolation transformer in industrial frequency UPS power supply:
It can filter load-side harmonics and improve the quality of power supply: the isolation transformer itself has inductive characteristics, and the output isolation transformer can filter out low-order harmonics at the load-side, reduce high-frequency interference, and can attenuate high-order harmonics. Power frequency UPS power supply isolation The transformer can also suppress the noise interference of AC power.
Reduce the zero-ground voltage and optimize the power supply network at the end of the UPS power supply: The inverter output of the industrial frequency UPS is equipped with an isolation transformer to isolate the electrical connection between the input and the output, thereby effectively reducing the output zero-ground voltage. Because the secondary winding of the isolation transformer adopts the Y-connection method, a new neutral line is generated after the neutral point is grounded, thereby achieving the purpose of reducing the zero-ground voltage.
"Passing AC and blocking DC", protects the load when UPS fails: The output isolation transformer has the ability of "passing AC and blocking DC", which can make the load run safely when the power frequency UPS power supply fails.
Enhance the overload and short-circuit protection ability and isolate the safe load(mini offline ups power supply): the isolation transformer is the most stable device in the industrial frequency UPS power supply. During the normal operation of the UPS, if a large short-circuit current is encountered, the transformer will generate a reverse electromotive force, which delays the impact of the short-circuit current on the load and the inverter and protects the load and the UPS host.
