How to regulate the voltage of laser power supply?

Along with the continuous development of economy in our country, most areas begin to produce electric power equipment, which makes the national grid electric power output insufficient, coupled with the aging of the power output facilities, eventually causes the voltage at the end of the circuit to be too low, which brings great influence on the stability of laser output. The stable output of laser energy is a necessary condition for laser production. The voltage instability will affect the laser frequency, production quality and production efficiency, and eventually cause unnecessary economic losses. In order to avoid this loss, should use the voltage regulator laser power supply, when the input grid voltage or load changes, the voltage regulator laser power supply can provide stable voltage for the laser through its own voltage regulator circuit, to ensure the stability of the light, prolong the service life of the laser.

So how does the regulated laser power supply achieve the regulated voltage work? In fact, when the external power supply input AC, through the transformer step-down, rectification, filtering will output stable DC. Voltage regulator laser power supply has a complete set of voltage regulator circuit, including adjusting circuit module, amplifying circuit module, sampling circuit module and reference voltage module, wherein the amplifier circuit module input is connected to the sampling circuit module, the output is connected to the adjusting circuit module, the other input is connected to the reference voltage module, the sampling circuit is connected to the capacitor group, The output end of the capacitor group is connected to the main board through the isolation circuit, the power supply is connected to the load, through the sampling circuit to obtain the output voltage, the output voltage is compared with the reference voltage, if the output voltage is less than the reference voltage, the error value will be amplified to the input end of the regulator, the regulator began to increase the output voltage until the amount is equal to the reference value.

Voltage regulated laser power supply has a wide range of power input requirements, enough to meet the existing common voltage input, and its power consumption is small, high efficiency, stable voltage input, also has overvoltage protection (over the output voltage) +10%, undervoltage protection (below the output voltage of -10%), phase loss protection, short circuit overload protection and other protection functions, when the grid voltage or load instantaneous fluctuations, The stabilized laser power supply will fluctuate at the speed of 10-30ms to compensate the response of the voltage amplitude value, so that it is stable within ±2%, to ensure the stable operation and safe production of the laser.
