IoT Power Sensor Unit DDS Series
No electrical work required! Just clamp onto two wires to visualize power!
■ Non-contact IoT power sensor unit that can be installed on three-phase three-wire and single-phase three-wire/two-wire systems. By simply attaching it to two of the three wires (for single-phase two-wire, the L/N two wires), it measures the active power including power factor. Utilizing Bluetooth wireless technology and powered by a lithium battery, it operates for approximately three years. It can be installed not only in factory cubicles but also in distribution boards and panel boards, enabling power measurement for each manufacturing line and equipment. No electrical or wiring work is required, making it easy to visualize active power. ■ Accurate understanding of power consumption through power factor detection. Typical clamp-on type power meters calculate power values by multiplying the measured current value by fixed voltage and power factor values. However, the SIRC IoT power sensor unit can detect the power factor. By multiplying the measured current value by the detected power factor simultaneously, it accurately determines the active energy consumption. For companies and factories, understanding the current accurate power consumption is essential for efforts towards carbon neutrality. The SIRC IoT power sensor unit allows for accurate measurement of power consumption, enabling effective CO₂ reduction (decarbonization) measures.

SIRC Corporation provides IoT sensors that can be retrofitted to existing equipment without large-scale construction for factories and plants. The main products include the "IoT Power Sensor Unit," which allows for easy measurement of power consumption for each piece of equipment and can be installed in about 15 seconds, and the "IoT Angle Sensor Unit," which can convert existing analog meters into IoT devices. Additionally, SIRC has developed its own cloud service, "SIRC Cloud," to visualize this data and support centralized management of on-site data. SIRC supports "on-site DX" that can be initiated while valuing and making the most of existing equipment.
