AB ++ is a traditionally installed ("on-cable") mosfet that transfers battery power directly to the motor via a high-power transistor, rather than fine mechanical contacts. This allows to increase the reliability and performance of the replica. Additionally, it enriches the replica with new, useful functions.
The mosfet is delivered with almost complete universal cabling, which enables installation in every replica. Only a few easy solders need to be made during the installation of the device.
Electronic burst: Change auto to an electronically controlled burst to save your ammo and increase realism!
Active brake: Active brake stops the motor after each shot preventing spring compression or in case of replicas with high rate of fire, overspin (double shot problem).
Precocking: Fast trigger response can be a matter of victory or defeat, especially in CQB situations. With precocking enabled, the piston will remain in rear position after each shot with the spring already compressed, ensuring that next shot will be fired immediately after you pull the trigger. To release the spring after using precocking, pull the trigger while simultaneously holding button on the unit. A shot will be fired, with no precocking and fully braked.
Rate of fire reduction: Reduce the rate of fire in automatic or burst fire to save ammo or make the replica shoot in a more realistic fashion.
DMR mode: Introduces intervals between semiautomatic shots to comply with DMR rules on some fields.
Low battery voltage alarm: Dedicated for Li-Po and Li-Ion batteries. Should the battery voltage fall to a dangerously low level, user will be notified by short sound signals that are repeated every minute. This may also be freely switched on and off.
Diagnostic system: Constantly monitors the replica and the MOSFET itself. In case of any problems, immediately lets you know what it might be, making troubleshooting much easier.
Electronic fuse: Will save your replica and battery in case of a major malfunction. It will automatically disconnect the battery if a short circuit or blocked motor is detected.
