Ii. Core Functions
High-reliability power supply
Provide a stable 24VDC power supply for ABB’s AC 800M controller and 800xA DCS system to ensure the continuous operation of the control system under harsh conditions, such as in the petroleum, chemical, and power industries.
The regulated output (±1%) and electrical isolation design prevent system abnormalities caused by voltage fluctuations or interference.
Comprehensive protection mechanism
Overload protection: When the output current exceeds the continuous value of 10A or the peak value of 14A, the power supply is automatically cut off to prevent equipment damage.
Overvoltage protection: Monitor the output voltage and trigger protection when it exceeds the range of 24VDC ±1%.
Short-circuit protection: Quick response when the output terminal is short-circuited to prevent circuit damage.
Iii. Application Scenarios
Oil and gas industry
Provide stable power supply for the wellhead control system and pipeline monitoring equipment to ensure reliable operation in extreme temperature and vibration environments.
Chemical and pharmaceutical industry
Drive key equipment such as the temperature controller and valve actuator of the reaction vessel to prevent production accidents caused by power fluctuations.
Electric power industry
It supplies power to the substation automation system and the generator set control module, supporting stable operation in high-altitude or coastal areas.
Metals and Mining
Provide redundant power supply in mining equipment and smelting production lines to reduce production disruptions caused by power outages.
Transportation and Infrastructure
It is used in rail transit signal systems and tunnel risk control systems to ensure continuous power supply in harsh environments.
