Power Integrations announces IEC-certification of CAPZero

Power Integrations has announced that its CAPZero automatic X-capacitor discharge IC has obtained IEC certification for IEC CTL DSH 1080, the new addition to the Certification Body (CB) system of the IEC60950 and IEC60065 standards covering X-capacitor discharge safety regulations. The company said the IEC-certified X-capacitor discharge IC saves time, minimises design complexity, and reduces cost.

CAPZero ICs are simple, SO-8-packaged, two-terminal devices that require only the addition of discharge resistors to automatically implement the X-capacitor discharge function.

New power supplies must comply immediately with the IEC CTL DSH 1080 requirement, which ensures that a power supply's X-capacitor safety-discharge function remains operational over the life of the product. CB-certified X-capacitor discharge devices such as CAPZero pass a stringent safety-testing protocol, including a lengthy period of high-temperature and high-humidity testing, and high-voltage line-surge testing.

Power supplies using a certified X-capacitor discharge device are deemed automatically compliant. Power supplies not utilising a CB-certified device, including those using discrete components or other non-certified ICs, must pass the same environmental tests as well as line-surge testing with all protection devices such as varistors and bulk capacitors removed. Any redesign would result in a need for re-certification of the power supply.
