Please click a question to see the answer.
- Q1
- According to Article 3 of the Rules for Voluntary Control Measures, "Testing and measuring instruments designed to be used for industrial, scientific, and medical purposes where the data processing function is a secondary purpose (i.e., ISM equipment) may be exempted from the rules." How about the following case as a concrete example of the above exemption? Is this printer regarded as non ITE off VCCI conformance requirement?
- Q2
- The Rules for Voluntary Control Measures says that testing and measuring instruments for medical use are exempted from VCCI control. I have a data processing system for medical applications used inside medical facilities. Is this system exempted or not?
- Q3
- I manufacture and market switching regulators to be built in ITE. Are switching regulators subject to VCCI control and, accordingly, is VCCI mark to be affixed on the product?
- Q4
- Do I need to measure mains ports conducted disturbance for an ITE operated by a battery?
- Q5
- In measuring conducted disturbance at mains portss, are there any distinctions made in standard between AC and DC of power supply? (Is only the AC case measured?) How about artificial mains network (AMN), are distinctions made between AC and DC? We use DC48V etc. for our products.
- Q6
- This is about AC adapters for ITE. The Electric Appliance and Material Safety Law prescribes requirements for AC adapters to meet. They are about noise voltage and noise power at mains ports for the frequency range 30 – 300MHz. I understand that ITE combined with an AC adapter is subject to VCCI control. As to noise voltage at mains ports of AC adapter, do you accept measurement done for the Electric safety law?
- Q7
-
- I have a DC powered ITE designed to be used in automobiles. However, it can also be used outside a car if you use an AC adapter. Is this kind of product subject to VCCI control?
- Is an ITE designed dedicatedly for a vehicle of amusement park subject to VCCI control?
- Q8
- Is PLC (Power Line Communication) equipment subject to VCCI control? If so, how can I carry out the measurement?
