Product Overview
The 9GT0412P3J001 belongs to Sanyo Denki San Ace 40T wide temperature range fan series, a 40×40×28mm DC axial cooling fan engineered to operate reliably under extreme low and high temperature environments. Rated at 12V DC, this industrial fan integrates 25kHz PWM speed regulation and a pulse tachometer sensor, delivering stable cooling performance for harsh industrial equipment operating from -40°C up to +85°C.
Constructed with a robust aluminum frame and UL94V-1 flame retardant plastic impeller, the fan complies with UL, CSA, EN and RoHS standards, ensuring safety and universal compliance for global electronic and thermal management projects. It features built-in locked rotor burnout protection and reverse polarity protection to avoid accidental motor damage during installation or operation.
