Four-Wire Three-Phase Kilowatt Hour Meter with RTU Protocol - Prepayment Electricity Meter
The DTS368-D is a DIN-rail mounted meter designed for three-phase, three-wire or four-wire systems, capable of measuring both active and reactive energy consumption. This modern smart energy meter, available in a 7-modular configuration, incorporates advanced technology to ensure high quality, stability, and excellent electromagnetic interference resistance. It also features low power consumption and adheres to international standards. Key advantages include its compact size, lightweight design, high precision, and suitability for applications such as office buildings, shopping malls, airports, and distribution boxes.
Main Features:
- Installation & Design: 35mm standard DIN rail installation, compliant with DIN EN 50022 standard.
- Configuration: 7 modular units, requiring a 125mm width.
- Display: LCD display showing 6+2 digits (six integers and two decimal places), with a maximum display capacity of 999999.99 kWh.
- Standards Compliance: Conforms to IEC 62053-21 and IEC 62052-11 standards.
- Reliability: Highly reliable operation with no need for calibration.
- Status Indication: LEDs indicate phases A, B, and C, as well as impulse and reverse conditions.
- Load Detection: Automatically detects the direction of load current.
- Measurement Capability: Measures three-phase three-wire active energy or three-phase four-wire active energy.
- Connection Options: Supports direct connection operation (up to 100A) or Current Transformer (CT) operation (1.5-6A).
- Data Communication: Meter readings available via RS485 Modbus RTU protocol.
- Measured Parameters: Tracks three-phase voltage (V), current (A), active power (kWh), reactive power (kVARh), and power factor (COSφ).
- Functionality: Multi-function capable, including reactive energy consumption measurement (kVARh).
- Tariff Support: Multi-rate functionality supports tracking total electric energy across different periods: sharp peak (T1), peak (T2), flat (T3), and valley (T4).
- Data Logging: Maintains 12 months of historical records for both active and reactive energy consumption.
