Introduction to the use of regulated power supplies for protection in laser cutting machines
The major purpose of the laser cutting machine's stabilized power supply is to monitor the compensation transformer to determine whether the voltage regulating transformer's temperature rise is normal and whether any unusual phenomena, such as coil overheating and discoloration, are present.
Verify the input and output voltages are normal, the state of the carbon brush's contact, the presence of any overload phenomena, etc.
Generally every three months, the metal laser cutting machine voltage regulator should have its dust and filth cleaned off in order to perform better maintenance;
Check to see if the chain transmission system is operating normally, grease the sprocket, tighten the chain as needed, and look for any slanted or stuck carbon brush holders and adjust them as necessary.
Additionally, examine the metal laser cutting machine's electrical connectors for damage;
If it needs to be promptly replaced or repaired:
Check the flexibility of the column-type voltage regulating transformer and the condition of the carbon brushes; repair any carbon brushes that are excessively worn or broken as soon as possible;
Use No. 0 fine sand to clean the contact surface of the coil quickly and remove any dust if there are burns or carbon brush powder marks there.
The laser cutting machine's stable power supply's protection mechanism:
The output power will be turned off after a delay of three to five seconds if the overvoltage output reaches 10% of the rated voltage (adjustable).
The output power will be turned off after a delay of three to five seconds if the undervoltage output is less than the rated voltage by 15% (adjustable).
Wait two seconds before turning off the output power.
The output power will be turned off after a delay of three to five seconds when the overcurrent exceeds the rated output current.
brief circuit Cut the output power if the load device has shorted out.
The machine will alarm and turn off the output power if the three-phase electric phase's reverse phase sequence is incorrect.
The machine will alarm and shut off the output power if there is a three-phase power supply phase shortage.
So what should we typically watch out for while using a regulated power supply?
The main knob should be turned to the first position, and then the fine knob should be turned, for example, if 13V is needed, the main knob should be turned to 15V first, and then adjusted through the auxiliary knob. 1. The first step in operation is to adjust the knob or button according to the actual required voltage and current.
The main knob shouldn't be set to 10V because that will prevent the voltage from rising to 13V.
2. You should first adjust to the necessary voltage if you need to utilize the load, then connect it.
3. The load must be detached, the voltage adjusted, and then it must be reconnected when utilizing a DC regulated power supply and it becomes required to modify the "coarse adjustment" gear.
4. If the load short circuit or overload protection occurs while the device is being used again, disconnect the load first, then push the "Reset" button to resume the voltage.
Once a fault has been fixed, the voltage can resume normal operation before connecting to the load.
