3-phase electricity meter Eastron SDM54-M
A small and handy electricity meter, 3 modules wide, with Modbus, CE approved and MID certified making it suitable as a billing meter.
- Three phase 100A direct feed
- MID B+D certified
- Class B accuracy (1%)
- Bidirectional measurement for active energy and power
- Configurable pulsed output (import/export and Net kWh)
- Modbus output
- Measurement of multiple parameters
- 3 modules mounted on DIN rail
The SDM54-M measures and displays the characteristics of single-phase two-wire (1p2w) and three-phase four-wire (3p4w) power supplies, including voltage, frequency, current power, power factor, active and reactive energy, imported or or exported.
Energy is measured in terms of kWh and kVArh. Maximum power and current demand can be measured for preset periods of up to 60 minutes. The SDM54 supports max. 100A direct load per phase. The meter is designed for DIN rail mounting, with IP51 protection on the front. The meter is equipped with RS485 Modbus port. Configuration can also be done via the keypad, which is password protected.
