All-in-One Integration
Integrates metering, protection, auto-recloser, and remote control into a single unit, eliminating the need for separate professional wiring and saving significant cabinet space.
Advanced Intelligence and Control
• High-Performance Core: Uses a 32-bit ARM microprocessor for real-time signal processing and smart control.
• Smart Operation: Features an automatic reclosing function with a fast closing time of 2 s.
• Remote Management: Supports "Four Remote" functions: remote signaling, telemetry, control, and adjustment.
• Easy Maintenance: Supports online remote upgrades for easy system updates.
Comprehensive Circuit Protection
• Three-Stage Protection: Provides long-delay, short-delay, and instantaneous electronic tripping that is independent of power voltage.
• Reliable Safety: Offers high breaking capacity to ensure reliable short-circuit protection.
• Adjustable Parameters: Protection for over-voltage, under-voltage, phase loss, and neutral loss can be set and modified online.
• Fault Tracking: Identifies and stores trip types (such as overload, voltage faults, or phase loss) for later query or deletion.
• Temperature Monitoring: Real-time temperature monitoring for the incoming terminal block and contacts (optional).
High-Precision Measurement and Display
• Accurate Metering: Measurement accuracy for 0.05In to 1.2In reaches Class 1.0.
• High Precision: Current and voltage accuracy reaches up to Class 0.5s, while active/reactive power accuracy reaches Class 1.
• Real-Time Data: Displays three-phase voltage and load current in real time.
• Detailed Parameters: Measures active power, reactive power, apparent power, power factor, and total active energy.
• Dual-Language Interface: Equipped with an LCD screen supporting both English and Chinese for easy use.
Advanced Connectivity and IoT Features
• Multiple Protocols: Automatically identifies and supports both DL/T645 and Modbus protocols.
• Wireless Communication: Features plug-in HPLC modules and low-power Bluetooth wireless communication.
• Flexible Modes: Offers time-control and fee-control (billing) modes for different application needs.
Specialized Monitoring and Protection (Optional)
• Power Quality Monitoring: Supports monitoring for active/reactive demand limits, current surges, harmonics, and waveform distortion.
• Green Energy Ready: Includes passive islanding protection and power generation quality monitoring for renewable systems (optional).
• Balance Protection: Monitors and protects against three-phase imbalance in power generation current (optional).
