PWM Controller
■ Features
Reduces system power consumption and fan noise
For PWM fan speed control, a PWM control circuit needs to
be newly designed and configured.
By using this product, however, PWM control function fans
can be fully utilized without the need for preparing new
circuits, contributing to reducing the system power
consumption and the fan noise.
Can be common-powered by the fan power supply
The controller can be powered by the fan power supply of
rated voltage 12, 24, and 48 VDC, and no separate supply is
required.
BOX Type
Maximum of four fans connectable
Up to four fans with PWM control function can be connected
and controlled.
