Wireless Current Sensor – 3-Phase

EPH-C30 | Wireless Current Sensor – 3 Phases


Phantom EPH-C30 is a Wireless Current Sensor with 3 channels (Amperage) which uses a simple installation to easily monitor the 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.

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.
