Product description: Zamel Supla MEW-01 Lite - 3F + N WiFi electricity consumption monitor
The Zamel MEW-01 Lite module allows for remote electricity measurement for 3 phases via wireless communication. The Lite version has a built-in WiFi antenna, which makes it suitable for small switchboards with plastic doors. The module is mounted directly on the TH35 DIN rail, it takes the place of two modules. MEW-01 is a 3-phase, bidirectional monitor, so it is suitable for both input and feed-in monitoring. Data is collected in the Supla mobile application and can be sent via MQTT. The set also includes 3 SC-16 100 A transformers .
Our offer also includes the Zamel MEW-01 version with an external antenna - check it out!
