Perun AB++ Programmable In-Line MOSFET with Active Brake

The Perun AB++ is a versatile inline MOSFET unit engineered to pack high-end computerized trigger control into an accessible on-wire layout without requiring complex gearbox disassembly. Featuring a specialized, high-power solid-state transistor, the unit routes current directly from the power pack to the motor. By taking heavy electrical loads away from vulnerable mechanical switch assemblies, it completely prevents contact burnout, lowers total system resistance, and boosts rate of fire and battery efficiency.

Beyond circuit protection, the AB++ integrates a sophisticated feature set that can be reprogrammed in seconds in the field. Using a combination of the physical onboard button, the weapon's trigger, a multi-color LED status diode, and intuitive sound cues, adjustments can be made on the fly without programming cards or external cables. Designed to manage extreme gearbox upgrades, the module supports input voltages from 7V to 17V without restrictions on mainspring ratings.

• Precocking Mode: Holds the piston retracted before the shot, producing a real-steel instantaneous trigger break.

• Active Brake (AB): Halts motor inertia instantly after each cycle to stop piston overtravel, prevent double feeds on semi, and preserve gearbox shell longevity.

• Electronic Burst: Configures full-auto selectors into realistic multi-round bursts to conserve ammo.

• ROF Reduction: Dials down cyclic rates to emulate real-world service rifles or enhance control.

• DMR Timing Delays: Enforces programmed pauses between consecutive semi-auto trigger pulls to meet designated marksman field rules.

• Battery Safeguard: Microprocessor monitors voltage levels and sounds audible alerts when cells dip below critical thresholds.

• Smart Self-Diagnostics & Electronic Fuse: Automatically severs current during stalls, shorts, or jams, insulating motor brushes and lithium cells against damage.
