ZR20 resistive and capacitive overvoltage absorber is a brand new high-tech products. The product is developed to meet a standard GB/T2900.16-1996 capacitors, been called a "protection capacitors" for the absorption of impulse voltage exclusive high voltage capacitors, Distribution no sense resistor in series received after the load-side switching between and, It can operate effectively inhibited the transient over-voltage and high-frequency oscillation current, over-voltage waveform AFP Steep and amplitude reduction, coupled with the damping resistance, allowing rapid attenuation of high frequency oscillations.
