My information is that the required Voltage is 220Vac, at 60Hz. We also are having to retest EMC for this purpose. Best regards, Brian C. Delta-Q Technologies Corp.
From: Kunde, Brian [mailto:[email protected]] Sent: December-02-13 3:06 PM To: [email protected] Subject: Re: [PSES] Korean EMC Standards So I have to ask, what is the voltage/freq in Korea? Is it that different compared to other countries? I heard for Emissions they like 6db margin but will accept 3db. They do know that Measurement Uncertainty is (Plus or Minus), right?

Even when I know of the Korean requirement up front their voltage doesn't fit into the EU or US input voltage levels including plus/minus tolerances. So essentially the RF immunity gets runs twice once for the rational and once for the fuss-budgets. We also run EMI scans three times.

For example. Test should be done at Korean voltages and frequency. Korea likes to add the measurement uncertainty in the limits. Etc. So usually we re-test our product in a KN accredited lab in Korea.

Is anyone familiar with the differences between KN 22 and CISPR 22/EN 55022 and KN 24 and CISPR 24/EN 55024?
