Is the 220V electric valve powered via a UPS?
Thread Content
There is a project in which all the valves on site are 220V electric valves (around 300 units), with only a few pneumatic valves. Are these electric valves powered by UPS? Do hundreds of circuit breakers need to be installed in the control cabinet (or should wiring terminals be used instead?) ）
Answer: Regarding the power supply issue for these electric valves, a UPS can be used to provide power, which ensures the stable operation of the equipment. However, it is necessary to determine the number of electric valves that need to be powered, as well as the number of circuit breakers that should be installed in the control cabinet, based on the power capacity and quantity of the UPS units. If the UPS power supply is insufficient, unstable power supply or power outages may occur, which can severely affect the normal operation of the equipment. As for whether hundreds of circuit breakers need to be installed in the control cabinet, it depends on the specific project requirements and safety standards. If it is necessary to install multiple circuit breakers, using wiring terminals to connect the cables of the electric valves is also a good solution. .
Is there no dual-power supply? With over 300 electric valves, just a UPS is not sufficient; a UPS provides emergency power supply. There is a separate circuit breaker for each circuit in the control cabinet, and if terminal blocks are used, fuse terminals are required.
This power supply is generally provided by the electrical control cabinet, and is not within the scope of the instrument power supply.
UPS does not supply power to electric valves; to ensure safety, a dual-power supply must be used
