DC Electronic Meter--GSH6225.8B manufacturer
Simplified system structure, reduced failure probability
The DC measurement and control system does not need to process complex parameters such as the phase and frequency of the AC power, the circuit design is simpler (such as eliminating the rectification and inversion links), and the number of components is reduced, thereby reducing the probability of failure caused by component aging, poor contact, etc.
Fast dynamic response, control accuracy can reach micron level
The speed and position control of DC motors, actuators and other equipment can be directly adjusted by DC voltage/current, with fast response speed (millisecond level), and control algorithms (such as PID control) are easier to achieve precise adjustment.
FAQ
1. What is DC electronic measurement and control?
DC electronic measurement and control refers to the electronic measurement and control technology for DC circuits or systems. Through sensors, controllers, actuators and other equipment, it can realize real-time monitoring of DC voltage, current, power, temperature and other parameters.
2. What is the main difference from AC measurement and control?
DC measurement and control processes constant or slowly changing DC signals (such as 0-1000V DC voltage), and AC measurement and control processes alternating signals (such as 50Hz sine wave).
3. What is the key to DC power measurement?
Dynamic response: synchronous sampling of voltage and current when the load changes suddenly; Noise suppression: switching power supply ripple and electromagnetic interference (EMI) in the DC system may cause measurement deviation, and low-pass filtering or shielding measures are required.
