Frequently Asked Questions — A402002

Does A402002 connect directly to mains power?

Yes. A402002 runs directly on 110 V / 220 V AC, 50/60 Hz — no external power supply or driver is needed, which simplifies wiring inside cabinets and appliances.

Can the speed of A402002 be adjusted?

AC fans run at a fixed speed determined by mains frequency. If you need variable speed, we can quote an EC version of the same frame size with 0–10 V or PWM control.

What capacitor does A402002 use, and can it be replaced?

A402002 uses a certified running capacitor matched to the winding. Replacements are available from us; we do not recommend third-party capacitors with different capacitance or voltage ratings.

Is A402002 suitable for continuous 24/7 operation?

Yes. A402002 is designed for continuous duty in machine cabinets, welding equipment and workshop panels, with 100 % aging test before packing and an expected L10 life of about 30,000–40,000 h.
