Application Scenarios
The SLC611-Z and SLC621-M-Z excel in various smart energy management and home/industrial automation use cases:
Residential energy management, enabling remote On/Off control and real-time energy consumption monitoring (including wattage (W) and kilowatt hours (kWh)) of connected devices such as lamps, space heaters, fans, and small household appliances via mobile App.
Smart device automation via scheduling, allowing users to set timed On/Off operations for electronics (e.g., decorative lights, daily-use appliances) to optimize energy usage and enhance convenience.
ZigBee network enhancement, functioning as mesh nodes to extend the communication range and strengthen the stability of ZigBee networks, thereby improving connectivity for other compatible smart devices in the system.
Small-scale commercial and industrial energy monitoring & control (e.g., in offices, convenience stores), leveraging their 35mm Din Rail installation design for easy integration into distribution boxes, and supporting load control via dry contact outputs to manage energy consumption of small commercial appliances while tracking accumulative and instantaneous energy usage.
OEM components for energy solution providers, offering smart energy monitoring and control upgrades for scenarios like residential complexes, rental properties, and small commercial spaces, thanks to their lightweight design, easy installation, and reliable energy measurement capabilities (with accuracy of ±2W for loads ≤100W and ±2% for loads >100W).
