ula, Cl units of anal F. The relationship between the resistance and capacitance values is arbitrary. Capacitor selection should be considered to meet the required current relay KA, can be calculated as follows: C Christine wherein Bu desired current relay KA, A; stupid - reliable factor, taking a 2.5 chu ~ 3; U. - Rated capacitor voltage, v; f power frequency, the frequency is 50Hz.
