‘Isolated’ refers to a circuit separated from the AC line in order to prevent electric shock. A ‘non-isolated’ circuit is one not shielded from the AC power source, making electrocution possible. Applications requiring isolation circuitry include TVs and A/V sets. ROHM offers a lineup of power modules (i.e. BP5710-1, BP5716, BP5729) optimized for isolated equipment. A number of consumer devics – mainly appliances – typically are not isolated, ranging from washing machines and hot pots to rice cookers and air cleaners.
