Product Introduction
The dual-power control cabinet achieves intelligent switching of power paths through a dual-power automatic transfer switch (ATS). When the primary power source experiences a voltage anomaly or power outage, the transfer switch completes the closing operation for the backup power source within 10 to 200 milliseconds. This process is monitored in real time by circuit current transformers, which feed signals to a microcontroller that controls an electromagnetic actuator to perform the mechanical switching. The core control module includes a voltage comparison circuit and a delay protection unit, which help prevent false operations caused by transient voltage fluctuations.
Functional Features
A dual safeguard mechanism—electrical interlocking and mechanical interlocking—is employed to eliminate the risk of two power sources operating in parallel.
It features an integrated RS485 communication interface, supporting remote monitoring of power supply status as well as query of switching records.
Equipped with an overcurrent protector and a temperature sensor, the circuit breaker trips when the current exceeds the limit or the internal temperature rises above 85℃.
Configure a power failure alarm device and a voice alarm system. When the main power supply is cut off, a multimodal alert will be triggered via audible and visual alarms as well as voice prompts. Integrate a voice-controlled lighting module that activates the lighting function upon receiving a voice command during an alarm.
Application scenarios
Firefighting power supply guarantee
In fire protection equipment power supply systems, the dual-power control cabinet serves as an end-stage switching device, ensuring that critical equipment such as fire alarm systems and smoke exhaust fans automatically switch to backup power sources—such as diesel generator sets—when the main power supply is interrupted. The 2024 improved model features a wall-mounted split installation structure that enhances its seismic performance, making it suitable for environments with frequent vibrations, such as subway tunnels.
Smart Water Supply System
In scenarios where municipal water supply pressure is insufficient, the control cabinet provides an uninterrupted power supply to the pump unit. Technically speaking, its built-in power protection unit continuously compares the quality of two power sources in real time and prioritizes the power path with greater voltage stability.
