VFD500 air conditioner VFD
VFD500 inverter for central air conditioners is a high-efficiency device designed for central air conditioning systems. It uses advanced vector control technology and can automatically adjust the output voltage-frequency ratio according to the motor load rate, thereby realizing intelligent energy-saving control of the system. This inverter for central air conditioners not only improves the overall efficiency of the motor and system, but also greatly reduces the energy consumption, noise and vibration of the motor.
Application
VFD500 inverter for central air conditioners is particularly suitable for compressor equipment in water-cooled units and other HVAC systems. It can easily optimize the cooling capacity of constant temperature and pressure, ensure that the equipment always maintains a stable cooling effect under different load conditions, and meet the needs of efficient and energy-saving operation.
Product features
1. Small size: For the same power model, the size is reduced by more than 40% on average compared to the company's MD380 general-purpose inverter
2. Wide voltage range: Rated input three-phase AC 380 ~ 480 V, wide voltage up to 323 ~ 528 V
3. Long life: The busbar capacitor configuration is higher, and the design life is up to 10 years
4. Good protection performance: When the fan is accidentally short-circuited due to stalling or damage, the fan drive circuit can effectively protect it; the entire series can achieve effective protection of output short-circuit to ground, and buffer relay (contactor) pull-in fault protection
