Gearbox V2 ASCU2 Gen.5

ASCU is a two-piece electronic module (consisting of a command unit
and a sensor unit), which, once installed in airsoft replicas, significantly
improves their operation. A traditional connector circuit was replaced with
a sensor unit that monitors the current location
of the sector gear, fire mode selector
and trigger. Collected information is transmitted to the command unit – where the software in the CPU analyzes them and
controls the motor of the replica via the active MOSFET brake.

ASCU improves gearbox V.2 operation and causes the replica to match
the most expensive and complicated PTW replicas.

ASCU oversees the replica’s operation no matter the speed with which the
trigger was squeezed and it is responsible for completing a full cycle of the
piston’s operation, both in semi-auto and full-auto modes.  After each shot,
the piston stops in its starting position.

ASCU features a Low Drain Protection system specially designed to protect
lithium-ion batteries (LiPo) from damage.

ASCU stops the replica’s firing cycle in case of any problems, thus protecting
the internal elements from further damage.

The
sensor unit monitors the
operation of the sector gear and thanks to that the whole system is capable of
completing full cycles of the gearbox operation (a BB will never remain in the
barrel when the magazine has been pulled and the spring will never be strained
when the replica is idle).

– ASCU unit is adapted for operation with new sensors that will prevent
firing shots when the magazine is empty or
when using an “M” type replica, they will force the usage of the bolt release
button after insertion of a new magazine.

– The unit expedites the reaction of the trigger in an AEG replica, which
in comparison to the ordinary unit, is
practically instantaneous.

– It prevents accidental, double shots: when the trigger’s consecutive
squeeze is faster than a human reaction – each squeeze amounts to one shot.

– Easy-to-install unit replaces
connectors and an anti-reversal latch in any V2 gearbox, whose elimination
completely reduces the jamming of the piston. Furthermore, it guarantees that a
replica will complete a full cycle every time (the spring will remain in the loose state).

– ASCU controls the charge level of a battery and does not allow its
over-discharge, which is very important when utilizing lithium batteries (LiPo, LiIon, LiFe).

– The module detects issues and malfunctions by emitting a sound and
vibrations as well as cutting off the power source, thus preventing further
damage in a GB.

– In replicas equipped with an operational
bolt-catch mechanism, by cooperating with the dedicated
Hop-Up chamber, the unit eliminates empty shots, which means it is impossible
to fire a shot when the magazine is not feeding BBs.

– ASCU significantly prolongs battery lifetime.

– It provides more possibilities than Systema
Revolution or PTW at a significantly lower cost of installation and allows to
make use of a wide array of spare parts available for standard V2 and V3
gearboxes.

– Easy programming of fire modes in following configurations:

 Safe + Semi + 3 Rnd
Burst + Full Auto
 Safe + Semi + Full Auto 
 Safe + Semi + 3 Rnd
Burst 
 Safe + Semi Only

– Compatible with every standard and reinforced Gearbox V2 gearbox frame

– The product has a 36-month warranty only when installed by an authorized
service. 

What changes were introduced in the newest Gen.5 version?

In the case of the new module, functions and parameters
are similar to that of the previous model, however,
the new ASCU unit is stored entirely in the Gearbox. As a result, no additional
wiring and space in a replica a necessary. Furthermore:

1. New MOSFET module with a 6 times smaller resistance – it results in a
faster firing cycle, higher efficiency of the active brake, higher amount of
shots per battery charge and a smaller amount of generated heat.

2. New, stronger trigger
connector

3. New, reinforced design,
entirely covered with polymer

4. Easier installation

5. Software update with an
easier system programming

6. Improved cutoff lever

7. Improved selector plate

8. Compatible with all, also
reinforced GB V2

9. 3 years of warranty around
the world

ASCU unit has a CE certificate and adheres to the RoHS directive.
