Electromagnetic lock

The DSN series electromagnetic lock is an electrically controlled mechanical interlocking device designed to prevent electrical misoperations in high-voltage switchgear. It is primarily used to enforce mandatory locking of high-voltage switchgear doors and other locations requiring safety interlocks, thereby preventing unauthorized operations and inadvertent entry into energized compartments. As such, it is an indispensable interlocking device for power utilities. The DSN5 model is a combined electromagnetic lock that integrates a high-voltage live-indication device with an electromagnetic lock; it can receive signals via capacitive or inductive sensors to provide high-voltage indication and perform mandatory locking functions.

Product Overview

The DSN series electromagnetic lock is an electrically controlled mechanical interlocking device designed to prevent electrical misoperations in high-voltage switchgear. It is primarily used to enforce mandatory locking of high-voltage switchgear doors and other locations requiring safety interlocks, thereby preventing unauthorized operations and inadvertent entry into energized compartments. As such, it is an indispensable interlocking device for power utilities. The DSN5 model is a combined electromagnetic lock that integrates a high-voltage live-indication device with an electromagnetic lock; it can receive signals via capacitive or inductive sensors to provide high-voltage indication and simultaneously activate the mandatory locking function.
