3BSE005029R1通讯模块,3BSE005029R1怎么使用
电阻-电容抑制器优先用于产生
电压变化率高（dv/dt）。CI626A 3BSE005029R1超过RCs使用电压能力的大功率负载
夹紧装置，如MOV，通常可从装置制造商处获得。
电阻电容抑制器也优先于MOV，因为除了
吸收负载能量。
一般来说，RC缓冲器的电容值应与线圈的值相同，单位为微法拉
额定电压至少为峰值电源电压两倍的电流（安培）。电阻器为
通常等于线圈的直流电阻。3BSE005029R1通讯模块对于直流线圈，电容器通常替换为
一个“反激”二极管，其阳极指向线圈的负极。电阻器有助于
保持设备快速退出；如果不担心这一点，可以消除它。

Resistor-capacitor suppressors are preferred for low-current high-inductance loads that generate a
high rate of change in voltage (dv/dt). High power loads beyond the capacity of RCs use voltage
clamping devices such as MOVs, which are usually available from the manufacturer of the device.
Resistor-capacitor suppressors are also preferred to MOVs because they reduce EMI in addition to
absorbing load energy.
In general, the capacitor for an RC snubber should be the same value in microfarads as the coil
current in amperes, with the voltage rating at least twice the peak supply voltage. The resistor is
usually equal to the DC resistance of the coil. With DC coils, the capacitor is usually replaced with
a “flyback” diode oriented with the anode to the negative terminal of the coil. The resistor helps
maintain a fast dropout of the device; it can be eliminated if this is not of concern.
Most control and contactor manufacturers make suppressor accessories that can be conveniently
mounted on their devices. The following types are available from GE General Purpose Control,
