No need for power wiring, retrofittable! Battery-operated power monitoring unit.
WLM Series
Approximately 5 years of battery operation reduces power supply construction. Visualization of power in locations where power wiring is difficult.
Easily monitor power and energy remotely from distant locations with LTE-M communication! The LTE-M compatible energy measurement unit "WLM" series is an IoT measurement unit suitable for monitoring power and energy at multiple sites spread over a wide area, as well as equipment and devices scattered in the field. The measured data is transmitted to the cloud via LTE-M communication, allowing for remote monitoring and centralized management of power usage across multiple locations, replacing the manual visual measurement and verification tasks previously performed on-site. ■ Transmits measurement data to the cloud via LTE-M communication ■ Supports approximately 5 years of battery operation * ■ Can be installed in locations where power wiring is difficult ■ Supports remote monitoring of multiple sites and scattered equipment ■ Allows for device settings from the cloud ■ Supports remote monitoring via alarm emails ■ Can be used in conjunction with an AC adapter
