Eastron SDM630-EV V2 three-phase electricity meter

Eastron SDM630-EV V2

Three-phase multi-function electricity meter for measuring energy consumption when charging electric vehicles. The measured parameters include voltage (V), frequency (Hz), current (A), power (kW/kVA/kVAr), import, export and total energy (kWh/kVArh). The maximum current consumption can be measured at preset intervals of up to 60 minutes. This device measures and displays the characteristics of single-phase two-wire (1p2w), three-phase three-wire (3p3w) and three-phase four-wire (3p4w) power supplies.

The device supports direct current measurement up to 100 A, which eliminates the need for external current transformers (CT) - thereby significantly reducing costs and minimizing the risk of installation errors. Thanks to this concept, the operation of the unit is simple and cost-effective. Built-in communication interfaces include pulse outputs and RS485 with Modbus RTU protocol for easy integration into higher-level systems. The device configuration is password protected, ensuring secure operation and protection against unauthorized changes.
