Inferring the Topic

Q: Can I use this for 120V AC coils?

A: The standard "3MP4001" denotes 24V DC. However, Dopoochai produces the same mechanical relay with 120V AC coils under a different suffix (e.g., 3MP4001-120A). Check your specific order.

• Turn the onboard potentiometer (or external one provided in the Set) fully counterclockwise to set minimum voltage.
• Power on the module.
• Slowly adjust clockwise while monitoring the output with your multimeter until desired voltage is reached.

• “Dopoochai” – Not a recognized major brand in electronics or tools. Could be a seller name on Amazon, eBay, AliExpress, or Shopee.
• “3MP4001” – This looks like a chip part number (e.g., a MOSFET, regulator, or sensor) or a generic model number for a camera (3MP = 3 megapixel) or a tool set.
• “Top” – Might refer to “top set,” “top model,” or a clothing item (top).
