Load Regulation
External components setting C1 : Capacitor for input voltage smoothing C2 : For noise terminal voltage reduction C3 : Capacitor for Output voltage smoothing Capacitance : 3.3uF to 22uF Ripple current is 0.13Arms above. Rated voltage : 200V or higher Capacitance : 0.1uF to 0.22uF Rated voltage : 200V or higher Film capacitor or ceramic capacitor. Reduce the noise terminal voltage. The constant value should be evaluated in the set. Capacitance : 100uF to 470uF Rated voltage : 25V or higher, Low impedance part Impedance is 0.39 max at High frequency range. Ripple current is 0.1Arms above. Impedance of capacitor affects the output ripple voltage. In the absolute maximum ratings, the reverse surge voltage should be 400V or higher, the average rectifying current should be 0.5A or higher, and the forward surge current should be 20A or higher. 10~22 1/4W Reduce the noise terminal voltage. The constant value should be evaluated in set. Varistor must be used. It protects this part from lighting surge and static electr
icity.
