Application of Hall Effect Current Sensors in Rail Transit
In the traction system of a locomotive or EMU, high-precision voltage and current sensors are used to measure the voltage and current signals at the grid end and the traction motor end. High-precision sensors convert high-voltage signals or high-current signals into weak current analog signals to facilitate the identification of back-end acquisition equipment.
Application of Hall Effect Current Sensors in UPS power supply system
In the UPS power system, the closed-loop Hall effect current sensor is used to measure the output current, and the UPS controller performs feedback control based on this current to ensure the normal operation of the inverter power supply. Due to its fast response time, it is particularly suitable for uninterruptible power supplies in computers.
Application of Hall Effect Current Sensors in photovoltaic new energy system
Hall effect current sensors play an important role in monitoring and controlling photovoltaic power generation systems. In photovoltaic power generation systems, the magnitude and flow direction of current are important indicators for monitoring and control. Hall effect current sensors can measure and monitor the output current of photovoltaic panels with high precision, and transmit these current signals to the inverter. The inverter controls and adjusts based on these signals to ensure the stability of the photovoltaic power generation system and efficiency.
Application of Hall Effect Current Sensors in electric welding machines
In the welding machine power supply, the Hall effect current sensor plays a measurement and control role. Its fast response can reproduce current and voltage waveforms and feed them back to controllable rectifiers A and B to control their output. Using a chopper to superimpose DC with AC can control the current more accurately. Using Hall effect current sensors for current detection can measure the true instantaneous value of the current without introducing losses.
