YINGHUA

YINGHUA V1.2 Automatic Shutdown Module CR10 Reprap 3.3-5V

SKU CH-D71W-AEY3E

An automatic shutdown module cuts mains power to a CR-10 printer when a print finishes, accepting 3.3–5 V logic and 85–265 V AC input

  • Automatic power-off saves energy after prints finish
  • Resume-printing support protects work during outages
  • Wide AC input range fits 85-265V supplies
  • Logic-level compatibility covers 3.3-5V controllers
  • PCB construction keeps module light and compact

Automatic Shutdown Module for CR10

The YINGHUA V1.2 module adds automatic power-off to a CR10 or RepRap 3D printer. It monitors the print job and cuts mains power once the project is detected as complete. The unit accepts a logic input of 3.3V to 5V and switches an AC load between 85V and 265V. It also includes short-circuit detection for added safety.

Makers automating print farms

This module suits operators who want unattended prints to finish without the machine idling overnight. It supports a resume-printing function after a power loss, helping recover long jobs. Builders using control boards that cannot supply a 3.3V to 5V logic signal will not be able to trigger the shutdown. Users needing DC switching or a different AC voltage range should look at other solutions.

85V to 265V AC switching range

The relay handles mains voltages from 85V up to 265V AC, covering most household supplies worldwide. The logic side operates from 3.3V to 5V, compatible with typical microcontroller outputs. Confirm that your printer’s control board can provide this logic level before purchasing.

Questions about this item

How much AC power can the module handle continuously?

The module accepts AC input from 85V to 265V, covering standard mains voltages worldwide.

Does the board generate noticeable heat or noise during a full-day print?

It is a passive PCB with no fan or moving parts, so it runs silently and adds negligible heat to the enclosure.

What printer electronics are required for the logic connection?

The logic input works with 3.3V to 5V signals, compatible with typical RepRap-style controllers such as the CR-10 board.
