Power Protection and Control Devices, Potential Transformer

Power protection and control equipment are used to monitor the voltage to a load to ensure it is within specified bounds. If an out-of-bounds level is detected, a protection and control devices can either regulate the voltage or current or switch off the power source to protect the load from damage.

For any detailed inquiries, please kindly send us your inquires. We will supply One- Stop Solution for you.

Power protection and control devices offer a range of power switches, to fully configurable overcurrent, overvoltage, and undervoltage monitoring. Specialized protection and control circuits manage redundant power systems and in-rush current for hot board insertion applications.
