Aiswei SDM630 Energy Meter (3-Phase, 100 A)

The Aiswei SDM630 3-phase energy meter is an advanced multi-functional device designed for direct current measurement up to 100 A in installations with Solplanet inverters. The device features bi-directional energy measurement, DIN rail mounting, and RS485 Modbus RTU communication.

The SDM630 energy meter is a dedicated solution for monitoring 3-phase network parameters. The device enables direct measurement up to 100 A, which eliminates the need for additional current transformers. The meter provides high operational precision, recording data with a 0.5 accuracy class for active energy. The design is adapted for mounting on a standard DIN rail and has an IP51 protection rating for indoor applications.
