Industrial-grade 170 mm fan for Mitsubishi inverters

This 170 mm case fan is built to the 175R-069D-0566 specification and operates on a 24 V supply drawing 3.5 A. It targets engineers and integrators who need a direct replacement for Mitsubishi inverter cooling assemblies. The four-wire connector provides PWM control and tachometer feedback for precise speed regulation.

Ball-bearing thermals with PWM speed control

The ball bearing design sustains continuous operation at the rated 24 V input without sleeve-bearing wear. PWM signalling on the fourth wire allows the host system to match airflow to thermal load, reducing acoustic output when full speed is unnecessary. Power draw remains at 3.5 A only when the inverter demands maximum cooling capacity.

Four-wire harness enables closed-loop monitoring

The bundled 4-wire harness delivers power, ground, PWM input and RPM output in a single connector, eliminating the need for separate sensor wiring. This lets the inverter controller verify fan health in real time and trigger alerts if speed drops below threshold. No additional software, lighting controllers or mounting brackets are included.

Questions sur cet article

How do I connect the 4-wire power connector to a 24 V supply, and what is the common polarity mistake?

Match the 4-wire lead to the inverter’s 24 V header; the yellow wire carries the PWM signal and must not be swapped with the red 24 V line.

Which part of the 170 mm ball-bearing fan wears out first and needs replacement?

The ball bearing assembly inside the 175R-069D-0566 rotor is the service item; when noise or vibration appears the whole fan unit is replaced.

At what current draw does the 24 V 3.5 A motor hit its thermal limit during continuous operation?

The motor is rated for 3.5 A at 24 V; sustained operation at that current is the design limit before overtemperature protection activates.
