Product Series: Choose the Right Model for Your Needs

6 Core Functions: More Than Just Protection

1. Comprehensive Protection (Avoid Motor Damage)

• Short circuit, phase loss, overload, and stalling protection
• Voltage sag (anti-interference/anti-sway electricity) protection (critical for continuous production)
• Leakage current protection and temperature monitoring (supports PTC/NTC/PT100 sensors)
• Customizable protection stages, start-up shielding time, and action settings

2. Flexible Control Options

• Multiple control methods (direct start, two-step start, etc.)
• Programmable input/output ports (up to 10 standard inputs, 6 standard outputs)
• Timer, counter, and logic programming functions (high-end models)
• Adapts to cabinet types: drawers, vertical cabinets, and control boxes

3. Precise Measurement & Monitoring

• Basic parameters: Three-phase voltage, current, power, energy, and power factor
• Advanced parameters (high-end models): 2-63rd harmonics, positive/negative sequence current, zero-sequence voltage
• Leakage current and temperature data
• Harmonic analysis (up to 63rd order) for energy optimization

4. Smart Operation & Maintenance Records

• Automatically logs start/stop events, fault history, running time, and fault counts
• Waveform recording (high-end models) for troubleshooting
• Disturbance recorder to track voltage fluctuations and anomalies
• Easy access to data for predictive maintenance

5. Versatile Communication Networking

• Standard protocols: MODBUS-RTU, PROFIBUS-DP
• Advanced options (high-end models): PROFINET, Ethernet, wireless networking
• Connects to PLC, DCS, and ECMS systems (common in power plants and large factories)
• Supports centralized monitoring of multiple motors

6. User-Friendly Human-Computer Interaction

• Clear display panels: Digital tube (basic models), monochrome LCD, or color LCD (high-end models)
• Simple operation buttons: Start, stop, reset, alarm, and ESC
• Intuitive interface for setting parameters and checking status

Industry-Specific Solutions

1. Power Plant Applications

• Needs: High reliability, waveform/fault recording, multi-protocol communication, anti-shake function
• Recommended Model: ARD3M (supports detailed parameter measurement and integration with DCS/ECMS systems)
• Associated Systems: Works with PLC, DCS, and ECMS for centralized motor management

2. Chemical Industry Applications

• Needs: Continuous production support, anti-interference electricity, fault recording, and multi-protocol communication
• Recommended Models: ARD2F, ARD3, ARD3M (ARD3M-K1-XX/SU-60L1 for anti-sway electricity)
• Key Feature: Anti-interference electricity function resists voltage sags caused by lightning, short circuits, or large load starts—preventing unexpected motor shutdowns
