3D Printer Part DIY HotBed Heating Platform Dual Voltage PCB MK2 b214x214mm

Description

Features: 1. 12V/24V power supply (random selection). 2. Double-sided panel, one side unwired for even heating and crisp prints. 3. Wiring is reversible (positive/negative). 4. This heated bed easily reaches 110°C. For bed temperatures exceeding 100°C, this model is ideal if you're looking for an effective solution to insufficient heating problems.

Test Report:

At 12V, the current is 9.8A. As the temperature increases, the current decreases to 8.8A (physical explanation: resistance increases with temperature).

At 24V, the theoretical maximum current is less than 5A.

Using 24V results in very high current, which can cause significant overheating of the MOSFETs and a risk of damage. Therefore, it is essential to ensure adequate power supply. A 576W power supply is very expensive, and an insufficient power supply can disrupt the operation of motors and other components. Also, check that the cable is thick enough to prevent it from overheating and becoming brittle.

Latest version mk2b:

Compared to the latest version Mk2a, the main improvement is its dual 12V/24V power supply.

12V connection: Connect one wire to terminal 1, then the other wire to terminals 2 and 3.

24V connection: Connect one wire to terminal 2, then the other wire to terminal 3 (wire 1 is left unconnected).
