The first generation of intelligent wireless monitoring module
The first generation of intelligent wireless monitoring module HD-WAM series product is a device that is mainly used to provide sound and indicator alarms when a lightning arrester
Second Generation SPD Online Status Monitoring Instrument
Performance Overview:
The HD-OLM-CH3 surge protector status online monitoring system is a comprehensive intelligent device that monitors the lightning strike count, leakage current, remote signaling switch quantity and surface temperature of surge protectors in real time. It is equipped with an LCD display and operation buttons for conveniently viewing real-time data, setting alarm threshold values and querying historical alarm data. It also has an alarm function - once real-time data exceeds the set threshold, an alarm sound will sound and the corresponding indicator light will light up. It is also equipped with an RS485 wired interface and a 2.4G wireless interface, enabling IoT and LAN networking. Through networking, real-time data collection, automatic monitoring and remote management of multiple surge protectors can be achieved, intuitively and effectively understanding the operating status and aging condition of surge protectors.
