Details

Fourth generation of PSJ processor is our most advanced unit yet and one of the most advanced units in the world. Cut-off lever has been completely removed to ease the installation, energy consumption has been lowered even more down to 3.7mA and the fire modes have been updated to give you even more options. Also, some new functions have been added, including LED indication of proper installation of both the gear wheel magnet and the trigger magnet. All this is on top all the great functions previous generations had, like contactless magnetic switching, powerful MOSFET cooled via the whole gearbox, adjustable power of active brake with possibility to disable it, programming by the trigger and so on.
GEN.4 updates overview

Unit size revised to fit into most gearboxes without any trouble.
Easier installation into your replica.
Cut-off lever not used at all.
Improved silicone wiring. Longer wires to allow use in any replica type.
Polarity of magnets does not affect functionality.
Updated fire modes now with possibility to set mode independently for “semi” and “auto”.
Burst can now be set differently for “semi” (burst1) and “auto” (burst2).
Whole new mode SEMI.
Lower energy consumption, as low as 3.7mA.
Can be used with spring up to M210 with rate of fire 99rpm.
 
Function overview of processor unit M2 Gen.4
Fire modes
Separate fire modes can be set for “semi” and “auto”
Configurable burst mode - from 1 up to 255 BBs shot on one quick trigger pull
Separate burst setting for “semi” (burst1) and “auto” (burst2)
Automatically switches from semi to burst or from burst to full auto without any delay when the trigger is pulled for a longer time
Modes are fully programmable by trigger itself
 
Rate of fire
Allows you to set delay (in ms) between the two following shots
Allows rate of fire setting (by % of the rate)
Programmable by trigger
 
Special functions
Default settings reset: You can simply reset all settings to their default values by the trigger
Manual mode: If your PSJ indicates damage and you are sure it is not mechanical and your replica is able to shoot, you can Access manual mode. In this mode, malfunction is ignored and you can fire on full auto mode only.
WARNING! By poor judgement, you can cause more damage to your replica and the unit!
SEMI only mode: Other fire modes will be ignored and replica will shoot only on SEMI regardless of fire mode selected by Selector (equals selector setting Safe - Semi - Semi)
 
MOSFET
No mechanical switch, switching is contactless
Faster trigger response
Increased rate of fire and battery life
Maximum current up to 202A constant and 808A in peek
 
Active brake
Stops motor immediately with piston in default position and spring loose (when 100% set)
Increases lifetime of piston, spring and many other parts
Always finishes whole rotation of gear wheels
Fully functional in all fire modes
Adjustable by steps of 10%
Possibility to completely disable active brake (set 0%)
 
Malfunction detection
Unit detects mechanical damage and disables shooting to prevent any other damage
User is warned by motor vibrations
 
Li-Pol/Li-Ion/Li-Fe battery check
When lithium battery is discharged, unit warns user by motor vibrations
Battery type needs to be set – easily done using trigger itself
Warning is off for Ni-MH, Ni-Cd batteries
 
Realistic trigger operation
Trigger sensitivity can be set during installation to best fit your demands
 
Anti-reversal latch
Solves problem with double shot on semi
Anti-reversal latch may not be needed if the motor is powerful enough (not recommended)
 
LED indication
Unit is equipped with LED indication for easier installation
LED located on the unit itself will indicate correct installation of magnet on the piston gear wheel
Indication supplements motor vibrations - it indicates what motor vibrations would
Malfunction indication can be used to determine correct installation of magnet onto the trigger
 
All this hidden inside your gearbox
The whole unit is installed inside your gearbox, replacing trigger contacts
Only two power wires come from gearbox
 
Generation 4 units are suitable for AEG replicas according to the version of gearbox each unit is designed for. Units have been tested in gearboxes of following manufacturers*: AimTop, APS, ARES, ASG Ultimate, Cyma, DBoys, Guarder, RetroArms, SHS, SRC
*Every manufacturer innovates their products over the time, so there is possibility, that the gearbox tested by us is different from yours. However this only means, that your installation might require some minor adjustments.
Technical parameters
Powerful MOSFET with maximum current up to 202A constant and 808A in peak allows use almost without any restrictions
MOSFET is effectively cooled by the whole gearbox
The whole unit is coated in multiple layers of varnish for maximum durability even in poor conditions
Replica‘s rate of fire is limited by gearbox components and technical specifications. PSJ unit itself is able to do up to 500 000 cycles (shots) per second. Unit is tested for 99 cycles (shots) per second
Current consumption of unit in standby mode is as low as 3.7mA
