The Single Phase Power Meter with internal CT are solid state transducers for measuring the current and voltage of fans, pumps, and other HVAC equipment.The current sensors are available in two types for either AC @ 300A or DC @ 100A applications.The connections are by Modbus.
The CS series current sensors can work on any supply, from 12V to 24V using either an AC or a DC supply. Data for the current and voltage are available over RS485 Modbus RTU protocol.
