Designed for High Current Loads
This expansion board solves the issue of excessive load current in 3D printer hot beds, providing stable performance under currents up to 20A with proper cooling.
It is essential for setups where the hot bed power requirement is 15A or greater, ensuring safe operation beyond the limits of many controller boards.
Compatibility and Specifications
Compatible with 12V and 24V power supplies, this module suits a variety of 3D printer models and improves heating control reliability.
Specifically recommended when total power usage reaches 240W at 12V, which demands about 20A current capacity that some controllers cannot handle.
Compact Size for Easy Installation
With dimensions of 60mm by 50mm, the board offers a space-saving solution that fits into typical 3D printer configurations without difficulty.
Stable Operation with Normal Cooling
Designed to operate reliably under standard cooling conditions as long as current does not exceed 20A during use.
Ensures protection for your printer's hot bed against overload and power issues.
Key Specifications
- Maximum current: 20A
- Voltage compatibility: 12V and 24V
- Dimensions: 60 x 50 mm
- Condition: New
- No high-concern chemicals
What's in the box

Product FAQ
Frequently asked questions
01 What is the maximum current this power expansion board can handle?
It works stable up to a maximum load current of 20A under normal cooling conditions.
02 Is this power module compatible with 12V and 24V systems?
Yes, the module is designed for use with both 12V and 24V power supplies.
03 Why do I need this hot bed power expansion board?
If your 3D printer hot bed requires 15A or more current, this module prevents overload by handling higher current loads than some controllers.
04 What are the physical dimensions of this expansion board?
The board measures 60mm by 50mm.
05 Can it be used with a ChiTu controller board?
Yes, it is recommended where ChiTu boards can only handle up to 15A and your hot bed requires more than that.
06 Does the module require additional cooling to operate safely?
The module operates stably under normal cooling conditions, but current should not exceed 20A during operation.
07 What happens if the current exceeds 20A on this module?
Exceeding 20A load current is not recommended as it may cause unstable operation or damage.
08 Is this product new or used?
The expansion board is brand new.
09 Does the module contain any high-concern chemicals?
No, it does not contain any high-concern chemicals.
10 Is the module customizable?
Yes, the product is marked as customizable according to supplier data.

I was going to use it for the ESP32 but it didn't work for me; it requires a 5V output and the ESP32 has 3.3V.
The advertisement says it's 30A, but the plate says it's 25A, but it seems that all advertisements selling this model of plate are like that!
received in a timely manner, of good quality
The screw thats on the bed terminals has been over tighten that it wont come off, the mosfet is no longer any good. waste of money. be careful on purchase, verify all terminals are able to be loosen and make sure the heater block is not lose. mine is.
