How Does The Line Fittings Select The Power Supply For The Ac Bridge?

How to choose the power supply of the AC bridge in Insulation Piercing Connector?

When the AC bridge can be used at low frequency, 50Hz industrial electricity can be used as the AC power supply. When in use, in order to stabilize the power supply voltage, an AC voltage stabilizer should be installed. In order to prevent interference from external factors, the power supply should be connected to the AC bridge through an isolation transformer. At present, the AC bridge usually uses a tube oscillator as the AC power supply. Since the RC oscillator is selected as the basic oscillation level, the waveform is good, the frequency is stable and the range is wide, and it has sufficient power, etc. There are also transistor oscillators as the power supply of the AC bridge. For some AC bridges with simple structures, buzzers are also used as AC power supplies. Its characteristics are that it has a certain frequency, generally 1000Hz, but the waveform is poor, so it is not suitable for use as a power supply for AC bridges with higher requirements.
