Operation Notes An excessively large capacitance at C1 may cause the output to become inactive. Therefore, a capacitance between 500F to 2200F is recommended, with a rise time of 10us or less. The capacitance of C3 should be 10F, since an excessively small value will result in malfunction. The activation time is defined as : t(s)=R2*C3ln[1-17/(VI-30A*R2)], where VI is the DC voltage after smoothing. The resistance of R2 should be 1.5M, since an excessively small value will result in malfunction. Overcurrent (reset type) and overvoltage (latch type) protection circuits are built in, preventing damage from occurring due to unexpected conditions. The overvoltage protection circuit shuts down operation once VDD exceeds 20V. In order to reset the input capacitor C4 must be discharged and the power turned back on.
