Wangdd22 3D Printer Hot Bed Power Expansion Board / Heatbed Power Module / MOS Tube High Current Load Module

Wangdd22 3D Printer Hot Bed Power Expansion Board / Heatbed Power Module / MOS Tube High Current Load Module

Wangdd22 3D Printer Hot Bed Power Expansion Board / Heatbed Power Module / MOS Tube High Current Load Module Features

  • 100%brand and new
  • Completely solve the hot bed power is too large and the load current issue
  • General Add-on Heated Bed Power Expansion Module
  • Helpful to solve the problem of hot bed's large power and the load current
  • Can work with the Anet A8
Notice:
Under the premise of normal cooling, it work stable under I(Max)=25A, the current must not exceed 25A while the process working

Description:
With this addon module to your 3D printer motherboard you can lead the maximum current up to 25A.
If you intend to use heated bed with your 3D printer that uses a 12V power supply, then this module is recommended, else it may cause excessive current during times which may burn the connectors on the controller board.
If you need anything greater or equal to 15A this module is a must! For example, if your total power usage is 240W and you have 12V power supply, then it means at least 20A is needed (20X12=240W). As ChiTu controller board is only capable of 15A this setting will not work. To make it work, you need this extra power module.

  • Easy No-Solder, No-Tape, No-Adhesive assembly and maintenance.
Descriptions:

●With PTFE in hot regions of our HotEnd we can reach 260C with the supplied thermistor. By swapping a thermistor for a thermocouple (may require additional electronics) you can reach over 280C.
●This not only allows you to print extremely high temperature materials like PP/ Polycarbonate and Nylons but also eliminates HotEnd meltdown failures associated . latest v6 hotend has a PTFE liner inside the hotend this liner is never subjected to high temperatures so there is no risk of damaging the liner through overheating.
●Our new HeaterBlock gives the fastest heat up times and the most responsive temperature control by clamping around the cartridge for maximum thermal contact. The new thermistor placement means you get the most accurate temperature readings with the fastest response. What this means for you the user is that you can go from 20C to 200C in just 65 seconds, temperature control is responsive enough that you can keep the hotend within 0.5C of your set temperature or less with ease.
