Description
Eastron SDM630-Modbus V2 Three-Phase Energy Meter
The Eastron SDM630-Modbus V2 is a direct-connected, multifunction DIN-rail energy meter for three-phase electrical systems. It measures and displays key electrical parameters and provides RS485 Modbus RTU communication for monitoring and system integration.
Key Features
- Direct connection up to 100 A, with no external current transformers required
- Supports 1P2W, 3P3W and 3P4W system configurations
- RS485 Modbus RTU communication
- Two pulse outputs for imported and exported energy
- Bi-directional measurement of imported and exported energy
- Password-protected configuration through the front-panel controls
- Four-module, 72 mm DIN-rail format
Measured Parameters
Voltage, current, frequency, power factor, active power, reactive power, apparent power, imported and exported active energy, imported and exported reactive energy, and maximum demand over selectable periods of up to 60 minutes.
