Description
Protect your 3D printer’s control board from the excessive electrical load generated by high-power heated beds and extruders. Many standard control boards are not equipped to handle the high DC currents required by these components, especially in 12V systems, which can lead to overheating or board failure.
The MKS MOS25 FET Heating Controller is designed to bypass this bottleneck, providing a dedicated power management solution that handles high-current loads safely. Rated for a maximum current of 25A (equivalent to 300W at 12V), this module ensures stable performance and long-term protection for your printer’s electronics. It is an ideal upgrade for both your heat bed circuit and your hot-end circuit.
Key Features
- High-Current Capability: Supports a maximum load of up to 25A, effectively handling demanding heating components.
- System Protection: Offloads high-power requirements from your primary control board to prevent thermal damage.
- Broad Compatibility: Suitable for 5V to 24V systems, making it highly versatile for various 3D printer configurations.
- Reliable Performance: Ensures stable power delivery to your heat bed and extruder for consistent printing results.
Important Installation Note
Always ensure that all wiring connected to the MOS25 module is correctly rated for the expected current and properly terminated to prevent electrical hazards. Do not exceed the 25A maximum limit.
