When any liquid is detected, the EA1540's beeper sounds, and its red LED lights up, calling for immediate attention and response, thereby effectively decreases the risks of damages to both the PDU and powered devices. It is ideal for PDU installation environments such as subway data centers located underground.Suitable for a wide range of applications, the EA1540 features a compact and anti-interference design, allowing it to avoid external signals from affecting its normal operations while saving valuable space for critical work. Built with corrosion-resistant materials, it is adaptable even to hazardous environments.The EA1540 is the perfect solution for those who need to ensure PDU's daily operations and prevent any potential risks of device damages in advance.
