Overview and Features
1. Frequency and Voltage Variable Function
· Accepts 3-phase AC power at 50Hz or 60Hz and varies frequency from 0 to 400Hz
· Supports 3-phase AC power and adjusts voltage up to the Up toimum AC voltage
· Fully performs the fundamental functions of VVVF (Variable Voltage Variable Frequency)
2. Convenient User Operation
· Simple operation using a 4-20mA command signal and dry contact for start/stop
· Easy access via industrial-standard MODBUS-485 communication
3. HVAC System Compatibility
· Optimized default settings for HVAC applications, enabling immediate use without additional configuration
4. High Power Efficiency
· Achieves higher power efficiency compared to conventional constant-speed operation
· Integrates with PMSM and ACIM compressors and fans in HVAC systems, including air conditioning units, chillers, and constant temperature/humidity machines
· Supports variable system implementation with the INB series to achieve high SEER (Seasonal Energy Efficiency Ratio)
5. Enhanced Protection Features
· Continuously monitors current, voltage, and temperature to safeguard the system
· Ensures stable operation through multi-x-layer current and voltage protection
· Provides predictive protective control, adjusting for environmental variations in current and temperature
6. Adaptive Protection Function
· Includes adaptive protection mechanisms to maintain inverter functionality without system shutdown
· Operates at optimal speeds to prevent shutdowns due to rising ambient temperatures
· Detects performance fluctuations in compressors and fans to adjust speed accordingly
7. Optimized Sensorless Operation
· Implements advanced sensorless control for stable low-speed operation
· Accurately detects mechanical speed without requiring an encoder
· Precisely controls fan and compressor speeds without the need for additional sensors
