Specification:
Size: approx. 60*50*31mm / 2.36 * 1.97 * 1.22"
Max. Current: 25A (Enhance heat dissipation)
Mounting Holes: 3.2mm diameter, for M3 screws

Feature:
High power module of general heating bed power expansion module for 3D printer.
Can be used on Chitu motherboards and other open 3D printer motherboards.
Help 3D printers equipped with controller boards (up to 15A) become more powerful.
With this add-on module, the maximum lead current on the board can be up to 25A.
This module is based on power MOSFET and will allow PID control of the heated bed (DC-DC Relays usually do not allow this).
If you intend to use heated bed for your 3D printer with a 12V power supply, then this module is recommended, else it may cause excessive current during the times, it can well protect the connectors on the controller board from burning.
For example, if the total power consumption is 240W and you have 12V power supply, then it means at least 20A is needed (20 x 12 = 240W).
Fine workmanship and good performance.
Easy to use.
Long service life.

Package included:
1 set x 3D Printer Module
