The document provides technical specifications for various series of multifunction meters, including the SFM118 Series Single Phase, SFM Series Phase, and DC 472M Series D Multifunction Meters. These meters are designed to measure a range of electrical parameters and support bi-directional measurement.
Specifications:
- Measurement Capabilities: The meters measure kWh, kVArh, kW, kVAr, kVA, PF, Hz, demand, voltage (V), and current (A). They support both import (IMP) and export (EXP) measurements.
- Pulse Output: The meters provide one or two pulse outputs for active energy measurement.
- Communication Interface: RS485 with Modbus RTU protocol is used for communication.
- Installation: Designed for DIN rail 35mm installation.
- Direct Connection: The meters can be directly connected with varying current capacities (e.g., 45A, 80A).
Display and Accuracy:
- Display: LCD with white back-light, capable of displaying up to 999999.9 kWh.
- Accuracy: Class 1, Class B with specific accuracy percentages for different parameters (e.g., 0.5% for active energy and voltage).
Environmental and Mechanical Specifications:
- Temperature Range: Operating temperature from -25°C to +55°C, storage temperature from -40°C to +70°C.
- Humidity: Operating humidity up to 90%, storage humidity up to 95%.
- Altitude: Suitable for use at altitudes up to 2000m.
- Withstand Voltage: AC voltage withstand of 4kV for 1 minute, DC impulse withstand of 6kV with a 1.2μs waveform.
Power Supply:
- Voltage range for power supply is 85-265VAC/DC or DC 24V.
