NB-IoT three-phase power meter with CT

The MyPM-03TA with ammeter transformers is a power meter that can be used in projects that involve monitoring the electrical energy consumed by a system and sending the data, via M2M NB-IoT wireless connectivity, to cloud platforms capable of analyze and aggregate them.

Equipped with a disconnector, the MyPM-03TA is capable of interrupting electricity; useful feature if you use a Pay per Use (prepaid) energy supply service.

• Power supply and DIN rail installation.
• Equipped with displays to check the readings and set parameters in real time.
• Data visualization on Contact Pro IoT in real time. Transmission frequency can be set based on the activated NB-IoT plan. 

Main advantages of the TA

• Suitable for residential and commercial systems.
• Wide range of current transformers available, from 50A to 1,000A.
• One current transformer per phase.
