140mm DC brushless fan 48V

 

1. The feature of over-current protection, the value of over-current protection is not bigger 4A when input voltage is 230VAC;

2.soft-start function

3. power factor≥0.99

4. circuit board over-temperature protection features

5. loss phase protection

6. the locked motor protection

7. relay alarm output: when fan bus overvoltage, under-voltage, driver circuit over temperature ,motor loss phase, the relay public contacts from close regular contact connect to open regular contact;

8. Reverse function: the fan can be reversed ,by use of computer or other controller setting control modes;

9. by RS485 communications and using MODBUS Protocol, a PC can also control 255 fans; the computer be able to control fan of start, stop, set the speed of the fan, and feedback status information: speed or a failed State;

10. auxiliary power output: the output 10VDC, Max 10mA

11. Speed control: online control modes: the speed blower is set by PC;

                  stand-alone mode: you can control the linear voltage by entering input-linear voltage or PWM signal control:0~10VDC,; starting voltage:1.2±0.2V .
