1、叶轮/Impeller
叶轮由塑胶材料PA66,玻纤增强注模制成,材料符合 ROHS 及阻燃UL-V0级。Impeller made of plastic PA66,fiberglass reinforced. All material accord with ROHS and UL-V0
2、电机/Motor
外转子直流无刷电机。转子上安装铁氧体材料,转子外壳表面电泳成黑色,材料符合 ROHS。
External rotor brushless DC motor ,Rotor with ferrite and coated in black. All material accord with ROHS
3、软起动/Soft Start
电机开始在低转速起动,大约20秒到达全速,以防止来自电源的电流冲击。The motor start at low speed,after 20 SEC running to full speed, to prevent current surges being drawn from the power supply
4、速度输出信号/Speed output signal
风扇输出一个与外接上拉电阻成比例的速度信号,风机每旋转一周,这个信号包含3个脉冲输出,信号最大幅值电压为12V。
The fan provides an output signal proportional to its speed with out pull up resistor. The signal comprises of 3 cycles per revolution of a squar. The maximum amplitude of the signal is 12 V
5、速度控制/PWM input
PWM输入控制电压范围:0~10VDC, PWM控制信号频率范围:1~10 kHZ
Signal voltage range: 0~10VDC
The frequency for control signal of the fan shall be able to accept 1~10 kHZ.
6、保护/Protection
