DC Inverters
For BLDC compressors
A dedicated inverter for controlling BLDC compressors that can be integrated into UX* PLCs. Through continuous control of the compressor speed, it can accurately manage load variations. Combined with the perfect combination with the electronic expansion valve, energy savings can reach more than 30%.
This driver adopts a position sensor-less 180-degree sinusoidal wave vector control solution to realize the drive control of the BLDC compressor. It has built-in bus voltage too low or too high and compressor phase loss protection, IPM module over temperature protection, compressor over current protection and other functions. Customers only need to control the logic of the product and use standard ModBus RTU communication to set the target frequency and read the inverter status to easily control the safe and efficient operation of the compressor.
Main functions
• Control functions include soft start and controlled shutdown, speed/torque control and power interruption capabilities
• Protection functions include overload/over-current protection, compressor operating range protection, under voltage/over voltage, high voltage cut-off and temperature protection
• Multiple maximum output power options: 3.5, 4.7, 6.5, 10.0 and 15 kW
• RS485 Modbus RTU communication standard
• 0-10V/PWM control option is optional
• Professional design, compliant with safety and EMC standards
