Power Supply Adapter apply standard IEC / EN 61558-1 for bridging the initial level (Primary & Secondary) capacitance requirement description
Power supplies commonly used Bridging Capacitor, when applying the standard IEC / EN 61558-1, paying particular attention to the following provisions.
According to standard IEC / EN 61558-1 section 19.8 of the requirements, you must use two or more in line with IEC / EN Y2 capacitors in series 60384-14 jumper in the initial stage of the circuit (as in the example arrows), but if the initial level circuit between the working voltage not exceeding 250 V, acceptable Use only single line with IEC / EN 60384-14 of Y1 capacitors connected across the primary and secondary circuits.
Special note is due to IEC / EN 61558-1 certified power use is very wide range, if the power supply to match IEC / EN 60335-1 (household appliances) apply safety regulations, based appliances IEC / EN 60335-1 requirements, you must use two or more compliance with IEC / EN 60384-14 series of Y2 jumper jumper in the initial stage of the circuit, the above does not apply to IEC / EN 61558-1 of exception clauses.
