A 230 V Signal Injector is a device used for testing and troubleshooting electrical circuits and components within systems that operate at 230 volts. They are commonly used by electricians, technicians, and engineers for diagnosing issues in power systems, electrical panels, and other 230V-rated equipment. These are designed to deliver specific electrical signals into the circuit to help identify faults, test individual components, and verify the functionality of various electrical systems and devices. 230 V Signal Injector is a valuable tool for diagnosing electrical faults and verifying the proper functioning of electrical systems that operate at standard line voltage.
