Especially, Confirm whether output current never exceeds a maximum standard with current probe. External components setting FUSE: FUSE C1: Input Capacitor C2: Output Capacitor Recommended the use of fast-acting type fuse 1.0A. Rated voltage : More than 450V Capacitance : 22F to 100F Rated voltage : More than 25V Capacitance : 100F to 1000F, low impedance type ESR : Less than 0.18 Rated ripple current : More than 0.62Arms Evaluate it with the actual opportunity because it influences an output ripple voltage. Rated voltage : More than 450V film capacitor, or Ceramics capacitor Capacitance : 0.1 to 0.22F ; Inductance : 1mH Rated Current : More than 0.41A It is changed electrical characteristics by winding direction of Power Inductor Resistance : 10 to 22 Power : More than 1/2W Peak reverse voltage : More than 800V Mean rectifying current : More than 1.0A Peak forward surge current : More than 20A This product can use even all the wave rectification. If capacitance for input voltage smoothing is large, please use rectifier diode that peak forward surge current is larger Be sure to use it to protect this product from thunder surge and the static electricity.
