Be sure to use fuse for safety.
Please verify operation and characteristics in the customer's circuit before actual usage. Ensure that the load current does not exceed the maximum rating.
External Component Specifications FUSE: Fuse C1: Input capacitor C2: Noise reduction capacitor C3: Output capacitor Use a quick-acting fuse of 2A Above 200V, 47 to 220µF Ripple current 0.22Arms or greater Above 200V, 0.1 to 0.22µF Use a film or ceramic capacitor. Evaluate under actual operating conditions. Above 25V, 330 to 1000µF, low impedance ESR : 0.08Ω Max. Ripple current 1Arms or greater Capacitor impedance affects effects the output ripple voltage Inductance : 330µH, Rating current : above 1.6A Select components that do not easily get magnetically saturated at high temperature. Above 400V, current : above 3A Fast recovery diode Please note that both the switching and efficiency characteristics of the module are affected by this diode. Recommended products : 31DF4 (Nihon Inter) or RU30 (Sanken) Use a rectifying diode with a peak reverse voltage of 400V or higher, an average rectification current of 1A or larger and a peak surge current of 20A or larger. When using a large capacitance input capacitor, select a component that is strong against inrush current during power up. Full-wave rectification can be used. 1 to 2.2Ω, 1/4W Reduce the noise terminal voltage. Determine the ideal value through actual testing. A varistor is required to protect against lightning surges and static electricity.
