Smart power supply surge protector SPD 40KA, mainly collects SPD damage status, air switch trip status, SPD false grounding, poor grounding, and SPD movement work times, configure standard RS485 interface data communication, support wired and wireless communication mode can provide custom programming interface. Smart outlet surge protector is convenient for electricians to connect with other private agreements.
No crash, adjustable starting threshold for accumulative counting, self-lightning protection, to ensure that it is not damaged by intrusion surge
40kA/80kA SPD optional, support wired and wireless transmission
The on-site alarm function can easily realize on-site management even if it is not connected to the Internet.
Remote alarm function, through the cloud server, a remote monitor any data collection terminal, acquiring the real-time alarm information.
