What is The Difference Between Industrial UPS and Commercial UPS?
Mar , 06 2024
An industrial UPS (Uninterruptible Power Supply) provides backup power to critical industrial equipment during power outages, fluctuations, or disturbances. The specialized purpose of an industrial UPS system is to serve as a power protection device designed for industrial environments. Industrial UPS systems meet the demanding requirements of industrial environments, where power disruptions can c...

What is the difference between three-phase current and phase current
Mar , 01 2024
The relationship between line current and phase current is as follows For a star connected motor, the phase current is equal to the line current. For motors with triangular connections, the line current is equal to √ 3 times the phase current, and the line current lags behind the phase current by 30 °. Phase current refers to the current flowing through each phase load in a three-phase power suppl...

Series and parallel connection of capacitors
Feb , 23 2024
Capacitor series connection: The total capacity decreases, but the withstand voltage value increases. The withstand voltage value is the sum of the withstand voltage values of two capacitors. Capacitor parallel connection: The total capacity increases, and the voltage withstand value is taken as the voltage withstand value of the smallest capacitor. If two capacitors are exactly the same, the volt...

Dc insulated relay DIW-2025
Feb , 03 2024
DIW-2025 (Type A, B, C)) DC insulation monitoring relay is a relay that monitors the insulation of the DC bus, and sends a warning signal when the insulation of the bus to the ground is reduced to a certain value. Structure and working principle. The relay mainly consists of a balance resistor and a detecting integrated circuit. When the resistance of the DC bus on both sides to the ground is equa...

Zero line electrification poses the following hazards
Feb , 03 2024
(1) When the zero line is disconnected, due to load asymmetry, the neutral point drift is caused, and the voltage of one phase of the light load will increase. When it exceeds the rated voltage of the electrical equipment, it will shorten the service life of the equipment. If it exceeds the rated voltage too much, it may even damage the equipment and cause a "group explosion" of household applianc...

AC & DC Maintenance Benefits
Jan , 26 2024
Introduction Maintenance is a necessary aspect of maintaining your critical backup power system and essential to ensure optimal performance when needed. What's the difference between an AC a DC UPS? An AC UPS transports electricity current over long distances, whereas a DC UPS is an uninterruptible power system that takes in primary power (usually utility AC) and outputs DC voltage, while providin...
