As a professional manufacturer, Comewill would like to provide you with quality Indoor High-Voltage Live Display Indicator DXN-Q/T III Lockout Type. We will offer you after-sales service and timely delivery. It uses non-contact sensing technology to monitor the energized status of high-voltage equipment in real time and provides a clear warning through a bright flashing light. More importantly, when high voltage is detected, it automatically locks the switchgear door, physically preventing personnel from entering the energized area. Currently, this product is widely used in various substations, power distribution rooms, and industrial plants and mines, becoming the "first line of defense" for on-site electrical safety.
The Indoor High-Voltage Live Display Indicator DXN-Q/T III Lockout Type is a "lock-controlled" high-voltage live display device.
Its working logic is very simple and direct: when high voltage is detected, a warning light illuminates and the device automatically locks; when the voltage disappears, the screen turns off and the device automatically unlocks.
Most ordinary live display devices on the market only provide audible and visual alarms. However, alarm signals can be ignored, and warning lights can be misread—human factors are always the weakest link in the safety chain.
Our Indoor High-Voltage Live Display Indicator DXN-Q/T III Lockout Type adds a layer of physical locking control:
When power is on: the display window emits a bright flash, and at the same time, the internal electromagnetic lock activates, locking the cabinet door. Even if someone tries to force the door open, they will be powerless.
In the absence of power: The display window turns off, the electromagnetic lock automatically releases, and the cabinet door can then be opened.
This dual locking system, combining visual and physical mechanisms, truly achieves a leap from "safety reminders" to "mandatory safety."
The DXN-Q/T III employs the principle of electric field coupling, sensing the electric field signal (6-40KV) of high-voltage charged bodies through a built-in sensor, representing a completely non-contact sampling method.
This means there is no electrical connection between the sensor and the high-voltage charged body; installation requires no alteration to the original cabinet structure and does not disrupt insulation; fundamentally eliminating the risk of leakage and short circuits.
Furthermore, the Indoor High-Voltage Live Display Indicator DXN-Q/T III Lockout Type's casing is made of industrial-grade flame-retardant ABS plastic, which is itself a high-quality insulating material. Even in humid, dusty electrical distribution room environments, it ensures that the device itself will not become a "conductor."
The DXN-Q/T III features an extremely simple structural design with no complex internal electronic components. Core components are all industrial-grade long-life selections:
LED Indicator Module: Long lifespan, low power consumption, high brightness
Electromagnetic Lock Module: Stable mechanical structure, reliable operation
Shell Material: Impact-resistant, aging-resistant, high flame-retardant rating
Under normal operating conditions, the Indoor High-Voltage Live Display Indicator DXN-Q/T III Lockout Type is designed for a lifespan of 8-10 years, requiring absolutely no maintenance during operation. For project owners, this translates to extremely low post-operation and maintenance costs and a very high return on investment.
The DXN-Q/T III comes standard with:
Standardized pre-drilled holes, eliminating the need for on-site measurement and drilling
A complete set of installation accessories (stainless steel screws, gaskets, etc.)
Clear installation instructions (text/video optional)
