    in reply to: 400W 8A buck converter: regulating power from solar panel to attic fan #35505

    Hello Gary，
    This item doesn’t have under voltage setting.
    8A is the max output current it can handle. Output current is mainly decided by load.
    Unless there is short circuit or other issue, the max output current will not be over 8A.

    Any more questions, please kindly contact us.
    Best regards.

    in reply to: YB27VA #35461

    Hello Nick,

    Thanks for writing in.

    YB27VA has several meters with different current measurement range.  Could you please let us know which one it is?

    Please kindly check below two wiring diagram. Both of them are available. If your meter is with 10A range, you don’t need to connect shunt.

    Best regards.

    in reply to: Shunt #35455

    Hello Scott D Elliott,

    Thanks for writing in.

    The 20A means if measurement range of meter is 20A, it doesn’t need shunt. 200075 is with 50A range, no matter how large the actual current it is, shunt is necessary.

    Best regards.

    in reply to: Is output pure dc? #35453

    Hello Tony Curtis,

    Output is DC voltage and current. Regarding to current ripple, would you mind waiting some times?  As our technicians have been out of office for holiday, we are sorry we can’t keep in touch with them now. Beg for your forgiveness.

    Best regards.

    in reply to: Product Code: 200128 I purchased one of these on Amazon ! #35452

    Hello Dan,

    Thanks for writing in.

    The power supply for 200128 is AC 110v. It can’t work with DC 12V.  The 12V in wiring diagram is auxiliary output. It is DC12v,30mA max.

    Best regards.

    in reply to: Time delay relay #35432

    Hello Matthew,

    Besides power supply connected to VCC and GND, could you please tell us if you connect the other power supply for load? The power goes through  VCC and GND is for powering on item only, it doesn’t offer power for load.

    Best regards

    in reply to: How to turn on constant current? #35423

    Hello David Mcwhorter，

    Could you please tell us which item it is?

    For most of our converters, current can’t be adjusted directly.

    Constant current regulation is for limit  output current. For example, when you set output current as 12A, actual output is mainly decided by load, but the max output will not be over 12A.

    Best regards.
