In the modern industrial field, uninterruptible power supply (UPS) systems play a crucial role. It can provide continuous and stable power supply to critical equipment in the event of power grid failure or interruption, ensuring the continuity and reliability of industrial production. As a key detection component, current sensors have been widely used in industrial UPS power supplies.
For example, CHIPSENSE CM4A H01 is a high-precision closed-loop Hall current sensor developed based on Hall technology, with a range of 1000A, a power supply voltage of ± 15-24V, an accuracy of 0.4%, and a response time of 1us. It is a key electronic component for current isolation measurement without insertion loss, low temperature drift, and high precision. Widely used in welding machine power supply, wind energy frequency converter and other fields.
1.Input and output current monitoring
The input current of industrial UPS power supply usually comes from the power grid or generator set. By monitoring the magnitude and waveform of the input current through a current sensor, the input situation of the power supply can be understood, and the stability of the power grid and the normal operation of the generator set can be determined. By monitoring the magnitude and changes of the output current through a current sensor, the working status of the load can be understood, and abnormal conditions such as overload and short circuit can be determined.
2.Battery charging and discharging current monitoring
Industrial UPS power supplies are typically equipped with battery packs to provide backup power in the event of grid failures. Current sensors can monitor the charging and discharging current of batteries, understand their status and performance, and determine whether charging or battery replacement is necessary. And used to optimize battery management strategies and extend battery life.
3.Inverter output current monitoring
Inverter is one of the core components of industrial UPS power supply, which converts DC power into AC power and provides stable power supply for load equipment. Current sensors can monitor the magnitude and waveform of the inverter output current, understand the working status of the inverter, and determine whether there is a fault.
The application prospects of current sensors in industrial UPS power supplies are broad. With the continuous advancement of technology, current sensors will provide more accurate and reliable current detection and control for industrial UPS power supplies, helping to ensure stable and efficient operation of industrial production.
