SDM630-DI is Digital Input RS485 Modbus Din Rail Three Phase UL Energy Meter.

This unit measures and displays the characteristics of Single Phase Two Wire (1P2W), Three Phase Three Wire (3P3W) and Three Phase Four Wire (3P4W) networks. The measuring parameters include voltage (V), current (A), frequency (Hz), power(kW/kVA/kVAr), power factor (PF), imported, exported and total energy (kWh/kVArh). The unit also measures Maximum demand current and power, which is measured over preset periods of up to 60 minutes.

SDM630-DI also comes with a complete comms capability with built-in RS485 Modbus RTU outputs and 2 digital inputs. This unit supports Max. 100A direct connection. Configuration is password protected.

The meter has been assessed and certified as meeting the requirements of UL 61010.
