Single-phase Power Meter

Name: Single-phase Power Meter
Rating: 5.0 (67 reviews)

Our single-phase power meters are versatile instruments designed for real-time measurement of AC or DC voltage and current across various electrical lines. They provide accurate and real-time power consumption data, enabling remote reporting of measured power data through RS485 communication or an analog transmission output interface, ensuring precise data collection. Additionally, the meters offer over-limit protection for the current or voltage of different electrical equipment by allowing customization of upper and lower limit alarm values. Inside the instrument, two sets of relay over-limit alarms are present, each with one normally open and one normally closed contact. Upon leaving the factory, the product provides three default current output signals: 0~10mA, 0~20mA, or 4~20mA. Consumers requiring customized voltage signal transmission output can make specific requests.
