EPH-C31 | Wireless Current Sensor - 3 Phases

Phantom EPH-C31 is a Wireless Current Sensor with 3 channels (Amperage) which uses three simple Current Transformer sensors for installation. Easily monitor the AC electrical current of your machines and devices.

This sensor is meant for either measuring 3 phases on a single motor, or else measuring 1 phase for 3 different motors. Includes 3 AC Split-Core current transformer clamps.
EPH-C30 can be set for a Range of 1 to 500 AMP. 

Additionally, this sensor can measure with precision the power consumption of your electric devices. Each sensor includes 3 simultaneous channels to measure each phase.

Condition Monitoring & Industrial Automation | Modbus

Wireless Modbus Current Sensor -- EPH Sensors include Modbus Protocol for industrial applications. Compatible with Condition Monitoring systems, Scada Systems PLC Etc.
Modbus is the most important Standard for Industrial Communication Protocol.

In conclusion, your Wireless Current Sensor is totally compatible with any PLC, Scada system or any other Modbus TCP / IP communication systemLearn more
