Fan 80x80x38mm, 12V DC, IP20, DBTB0838B2S

DBTB0838B2S is a powerful axial fan of 80 × 80 × 38 mm format designed for cooling devices with higher thermal load, where high airflow is required and at the same time the possibility of speed control using a PWM signal. It is typically used in server cabinets, industrial distribution boards, network elements and for blowing dense passives, where higher static pressure is also important.

Why choose this product?

• Compact industrial format 80 × 80 × 38 mm with high performance
• PWM speed control for integration into temperature-controlled systems
• Suitable parameters for applications requiring higher static pressure
• Ball bearing design for long-term operation

Installation and operating instructions

• When installing, observe the direction of air flow according to the arrow on the fan frame.
• Provide an appropriate 12 V DC power supply with sufficient current reserve
• For PWM control, use a compatible control signal according to the 4-wire fan standard
• In applications with higher contamination, we recommend using a filter and regular maintenance to maintain flow.

Safety notice

• The fan is a rotating device: do not interfere with the blades during operation and provide mechanical protection in the available installations
• Before connecting, disconnect the power supply and verify the correct polarity of the 12 V DC
• Observe operating temperature conditions and ensure sufficient cooling of surrounding components
