PLC Control Coloring Machine(EDAC-12)
The EOE-09A silicon controlled rectifier power supply is designed to provide reliable and efficient DC power for specific applications that require precise voltage or current control. It is particularly well-suited for processes such as aluminum alloy anodizing, surface hard oxidation of aluminum alloy pots, electrolytic container formation using aluminum foil, and electrolysis.
One of the key features of the EOE-09A power supply is its automatic voltage or current regulation function. By utilizing PID (Proportional-Integral-Derivative) adjustment, the power supply continuously monitors the output voltage or current and makes adjustments to maintain the desired levels. This ensures stable and consistent power delivery throughout the process.
Setting the output voltage or current is made easy with the digital setting capability provided by the PLC (Programmable Logic Controller). The PLC allows users to input the desired values digitally, providing precise control over the power supply's output.
To ensure the safety and longevity of the equipment, various protection mechanisms have been incorporated into the design. These include current limiting, voltage limiting, phase loss detection, and overtemperature protection. These safeguards help prevent damage to both the power supply and the connected equipment in case of any abnormal operating conditions.
The intelligent operation control screen provides a user-friendly interface for managing the power supply. Users can easily monitor the status, adjust parameters, view data, and identify faults through the intuitive display.
Furthermore, the power supply offers communication capabilities with an upper computer system via the PLC. This enables online control and data acquisition, allowing for remote monitoring and management of the power supply's performance.
Additional features of the EOE-09A power supply include soft start and soft descent adjustment functions. These functions enable a smooth and gradual startup and shutdown process, minimizing any sudden changes in voltage or current that could impact the connected equipment.
The intelligent touch screen further enhances the ease of operation by providing different modes of operation, such as stable voltage mode, stable current mode, and area mode. Users can select the appropriate mode based on their specific requirements.
In terms of usage criteria, the EOE-09A power supply is intended for indoor use. It is designed to operate within certain environmental conditions, including an altitude below 1000 meters (adjustments may be necessary for higher altitudes), a temperature range from -15 to +40 ℃, and a relative humidity below 85%. The installation site should be free from gases, vapors, chemical deposits, dust, dirt, or any other corrosive substances that could compromise the insulation of the power supply. Additionally, the site should be stable and free from significant vibrations or turbulence. Finally, fluctuations in the power grid supply should not exceed ±10% to ensure reliable and consistent operation of the power supply.
