DDLS200200.1-50-M12 50125767 Optical data transmission

DDLS200200.1-50-M12 50125767 are a large number of harmonics, lightning surges, high-frequency interference and other noise in the AC power grid, so measures should be taken to suppress interference from the AC power source for control devices and electronic and electrical equipment powered by the AC power source. The use of power isolation transformer, can effectively inhibit the noise interference into the AC power supply.

DDLS200200.1-50-M12 501257671 ordinary transformer can not completely play the role of anti-interference, this is because, although the primary winding and the secondary winding is insulated between the primary and secondary windings, can prevent the primary side of the noise voltage, current directly transmitted to the secondary side, there is isolation effect.

DDLS200200.1-50-M12 50125767 Noise in the AC grid is coupled to the secondary side through the distributed capacitance (between the winding and the core, between the windings, between the layer turns and between the leads). In order to suppress the noise, it is necessary to add a shielding layer between the windings, which effectively suppresses the noise, eliminates the interference and improves the electromagnetic compatibility of the equipment.
