IEC 62368 1 ed 2 0 2014 02 external circuit b IEC 62368 1 electrical circuit that is external to the equipment and is not mains Note 1 to entry An external circuit is classified as ES1 ES2 or ES3 and PS1 PS2 or PS3 Normal condition Steady state is considered established when the voltage values persist 2 s Example The insulation between ES3 and ES1 shall be R I or D I insulation Abnormal
The established safety standards for ICT equipment 60950 1 and AV equipment 60065 are to be phased out in favor of a single standard 62368 1 in North America and the EU The new standard introduces a different hazard based Under EN 62368 1 all electric circuits are now classified as PS1 PS2 or PS3 based on the electrical power available to the circuit from the power source The electrical power source classification is determined by measuring the
