The product is a multifunctional 3-circuit and 4-wire fan controller. The first circuit is used for automatic temperature control speed change, the other two circuits for potentiometer adjustment. The first and second circuits are also equipped with an optional open silence alarm.
At present, types of the four-wire fans which cannot be controlled by this controller are as follows:
1. TAIDA FFR0612VHE, FFR0612DHE: 6038 in size, fans of nonstandard inverse time sequence( inverse regulation for rotational speed)
ATTENTION: This is a four-wire PWM fan controller, which can only control the four-wire fans that meet the standardization terms of In-tel four wire( it fits all the PC cases and CPU four-wire fans; over 97% servers can be controlled by
violent fans),; two-wire and three-wire fans are out of control, and the fans cannot be totally turned off!
Information about Function Settings Switches:
TFL (NO.1): the lowest PWM setting for temperature control channel: 40% for FAN1 when it is on, 20% when off.
TP1 TP2 (NO.2, 3): Settings for temperature control range of the temperature control channel are as follows( collocating temperature probes in use is needed):
TP1 TP2 Temperature of Accelerating Speed Temperature of Full Speed
OFF OFF 35 degrees Celsius 45 degrees Celsius
ON OFF 40 degrees Celsius 55 degrees Celsius
OFF ON 50 degrees Celsius 70 degrees Celsius
ON ON 60 degrees Celsius 90 degrees Celsius
Output at the lowest rotational speed when the temperature is beneath that of accelerating speed, always output at full speed when the temperature is over that of full speed.
BF1 BF2 (NO.4, 5): Switches for Respective Silence Alarm of FAN1 FAN2: Once the switch is on, the channel fan breaks down and stops rotating, the controller will send alarm with sound and light( a buzzer is needed), and when the fan
starts again, the alarm will automatically disappear. If BF1 AND BF2 are both on, either or both of FAN1, FAN2 stops rotating, the controller will send alarm!
