AFE3010:AFE3010AIRGTT

Part Number: AFE3010

We are developing electric vehicle charger products. RCD must be built in.


There are 3 types of RCT types. (1) AC type (2) A type (3) B type
(1) AC type : Sinusoidal AC with rated frequency : AC 30mA
(2) A type : Sinusoidal AC and Pulsting DC up to 6mA : AC 30mA + DC 6mA
(3) B type : All kinds of current up to 1kHz

Where does AFE 3010 apply?

I am trying to design B type. At least we are trying to develop A type products.

ref : 60Hz , AC220V, detection  : AC 30mA, DC 6mA 

Do you have time chart ?

    Hello valued engineer,

    I am looking this over and will respond shortly.

    Sincerely,

    Hello,

    Is Type B mean that device needs to reject DC leakages <3mA and trip to all DC leakages > 6mA?

    The AFE3010 was designed to comply with UL 943, which is an AC type application, including single-rectified AC signals.

    It could be used to detect AC 30 mA RMS or 6 mA DC signal, but not both at the same time because this DC signal will be sensed by internal amplifier and superimposed onto the AC component and this will cause a premature trip at around 25.8 mArms.

    So the AFE3010 by itself is not a Type B RCD.

    Sincerely,

    Peter
