Sanyo Denki San Ace PWM Controller

The Sanyo Denki San Ace PWM Controller provides external speed control for PWM fans. It helps control fan speed without the need to design a separate PWM control circuit. The controller supports 12 V, 24 V and 48 VDC power supplies and can control up to four PWM fans. It can also use the same power supply as the connected fans.

Three control methods are available: voltage control, variable resistor control and thermistor control. The thermistor option can automatically adjust fan speed based on temperature. The series includes box-type and PCB-type controllers, with 25 kHz or 1 kHz PWM frequency options. Different models are available to suit different fan control requirements.
