ER-25KV Application Field and Working Principle
ER-25KV is a kind of emergency stop relay which plays an important role in the modern electrical control system. It mainly consists of a main contact, a flange with wiring terminals, a spring, a control switch, a signal indicator, and a fuse. It is usually installed at key points in the control circuit of all kinds of electric ads.
Application Field
ER-25KV is widely used in various kinds of electric drives. It’s perfectly suitable for robots, welding machines, manipulators, stone cutting machines, punching machines, elevators, cargo handling systems, as well as other AC motor drive systems. Its installation position can be both in indoor and outdoor settings, and its enclosure is usually made of aluminum alloy.
Working Principle
When the circuit board receives a signal from the braking current, the ER-25KV will be triggered by its internal crystal and output a controlled voltage that modulates the speed and braking of the target equipment. This helps improve the protection of electric appliances and the safety of personnel operating the machinery. The ER-25KV adopts modern relay with sensitive action and strong stability, so reliable performance is guaranteed.
In addition, ER-25KV adopts full automated production packaging for the complete system. It has passed the testing and certification of UL, CE, and CSA. Its integration is quite simple and straightforward. The integral unit has a generally easy-to-install design.
Conclusion
ER-25KV is an invaluable accessory for enhancing the safety level of both electrical appliances and personnel operating the machinery. It is a cost-effective way to protect expensive electrical equipment from over-voltage, over-current, short-circuit, and other hazards. For large-scale industrial production systems, this emergency stop relay plays an irreplaceable role in maintaining system accuracy and reliability.
