ASCU Gen. 3 Gearbox V. 2

The ASCU, or Airsoft Smart Control Unit, is essentially an advanced MOSFET capable of providing electric airsoft replicas with enhanced control and reliability. How does this MOSFET achieve this added comfort and reliability? By replacing the entire electrical system.

Starting from the beginning, this control unit establishes the connection between the consumer and the power source as safely as possible. Let's analyze the processes that are improved.

The classic contact made of brass blades is replaced with a micro switch that activates a series of high-power MOSFETs, eliminating the current loss generated by the closure of the classic contact.

The classic interruption module generating the semi-auto function, composed of a cut-off lever and a moving carbon brush, has also been replaced with a micro switch capable of sensing the slightest movement of the cut-off lever, thus signaling that it is time for the assembly to stop.

With the installation of the ASCU unit, the replica no longer requires a 4-6 mm travel to complete the operating cycle; 1-2 mm is sufficient to command the control unit, providing an extra level of control and comfort for the user. Regardless of the speed of the trigger pull, the gearbox will complete a cycle and then stop.

Thanks to the "fine" control of the commands, the gearbox can operate at optimal parameters. The sector gear will stop exactly in the position it needs to be, thanks to the active braking feature of the module. To be fair, this MOSFET requires powerful motors to function correctly, specifically to brake the entire assembly effectively.

With the installation of the ASCU unit, an anti-reverse is no longer necessary. Due to active braking, the piston will remain in the most forward position after each shot, keeping the spring in optimal conditions and eliminating the risk of the gearbox being under tension. The trigger safety is also no longer required.

If the battery no longer has sufficient voltage to operate the ASCU gearbox, it cuts off the power supply to prevent battery damage. If something malfunctions inside the gearbox and the ASCU detects an increase in load, it also cuts off the power supply to prevent more severe damage.

The ASCU control unit can be programmed to provide different firing modes according to needs.
