  • Mosfet targets the energy from the battery directly to the motor, bypassing the mechanical trigger contacts. In result, your rifle gains a higher rate of fire as well as faster trigger response. In addition, the trigger contacts are protected against burnout.
  • Debouncing, which provides full compatibility with micro-switches, ensures full resistance to contact bounce (vibration). You gain a bigger ROF, a faster trigger response and your MOSFET is less prone to overheating.
  • Automatic resettable Protection Against Reverse Polarity. This function protects the motor and MOSFET itself in the event of reverse polarity.
  • SMART FUSE, protects MOSFET in case of motor jam. The SMART FUSE prevents from overheating, overloading and over currenting.
  • The MOSFET is protected in case of short circuit of signal and motor wires. X-ASR does not require additional fuse in AEG installation.
  • BUILT-IN SELF-TEST – 2 LED allows for quick troubleshooting
  • Due to its special conformal coating, X-ASR is resistant to heavy atmospheric conditions (Military Specification MIL-V-173C)
  • In case of too strong AEG configuration, the SMART FUSE will turn off the MOSFET in order to prevent overheating.
