Describe

AMC16(L)-DETT base-station DC energy metering module is engineered for sites that require tenant-level billing but whose switch-mode power supplies lack per-user energy measurement.

It simultaneously meters 6 DC circuits while supplying operating power to the companion Hall-effect sensors.

An industrial-grade RS485 port with Modbus-RTU protocol and SGS-verified CE conformity ensure full compliance with EU standards.
