Model

MKS MOSFET Module (e.g., MKS MOS-24, MKS MOS-30, or similar)

Rated Current

30A+ (Supports high-power heat beds & extruders)

Input Voltage

12V - 24V (Compatible with most 3D printer PSUs)

Output Voltage

Same as input (Direct pass-through with MOSFET switching)

MOSFET Type

N-channel (High-efficiency, low-resistance switching)

On-Resistance (RDS(on))

< 5mΩ (Minimizes heat generation)

Control Signal

3.3V - 5V PWM (Compatible with 3D printer mainboards like MKS, RAMPS, etc.)

Max Power Dissipation

Depends on cooling (Heatsink or active cooling recommended for >20A)

Protection Features

- Overcurrent protection (varies by model)

- Thermal protection (heatsink required)

Connectors

- Screw terminals (for high-current wires)

- Standard PWM input (from mainboard)

Compatibility

Works with MKS Robin, SKR, RAMPS, Duet, and other 3D printer controllers

Applications

- High-power heat beds (24V silicone heaters)

- Extruder heaters

- Other high-current DC loads

Cooling Requirements

Heatsink + fan recommended for sustained high-current operation

Dimensions

Varies by model (typically 40mm x 30mm x 15mm with heatsink)
