Application: This high-power module is a universal hot bed power expansion module compatible with 3D printers. Can be used with anet a8.Unique design: The unique snowflake heat sink design has excellent heat dissipation effect. Hotbed power modules are available compatible with lerdge motherboards and other 3d printer motherboards.25A Max Current: This high power module helps 3D printers equipped with lerdge controller boards become more powerful. This module can solve the current load problem when the hot bed power is too large. With this add-on module, the maximum current on board can be up to 25A.Good protection: When the 3d printer heating bed uses 12v power supply, sometimes the current will be too large. Using this module can well protect the connector on the controller board from being burned out.Power supply/working voltage: 12v-50v (recommended 12-24vdc)Maximum current: 30A (increase heat dissipation), safe use compatible with a long time. Make sure to actively cool the radiator.Size: 70x45mmHole distance: 62.8x37.8mmVoltage: 12-50vColour:blackMaterial:pvc+metalPackage Contents:4 x module4 x Signal control line8 x Power wiring4 x Fan port wiringOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
