FOCUS ON EC FAN ONLY
In the new energy sector, the PB3N133B48H is a 48V dc backward curved centrifugal fan made especially for power electronic equipment heat dissipation. It provides 0~10V/PWM stepless speed control and operates on a secure 48V DC power source. This backward fan easily overcomes the resistance of heat sink fins and air ducts thanks to its large air volume of 360 m³/h and high static pressure of 382 Pa. This ensures that essential components like IGBTs and inverter modules are always at a suitable operating temperature, and the entire unit uses only 33.6 W. It is ideal for difficult situations like outdoor energy storage containers, charging heaps, and solar inverters because of its broad working temperature range of -25°C to 60°C and IP44 protection grade. It is the perfect option for effective heat dissipation of modern energy equipment because of its 50,000-hour lifespan and integrated stall protection feature, which completely ensure long-term dependability in unattended applications.
