MERF 3.2™ programmable AEG MOSFET Gen.3 with active brake
Multifunctional programmable 3rd generation MOSFET. The system has 10 functions. Its latest feature is the 3-rd Burst Mode, which allows for limiting the number of shots. The system allows for lossless rate of fire adjustment.
It protects Li-Ion batteries: LiPoly and LiFePO4. It has a built-in active brake and it protects contacts against damage. The Smart Trigger function enables achieving faster trigger response. Thanks to two operating modes, the system works with both the original and the modified AEG installation. The system is designed for all replicas and especially for the upgraded ones. It has been adapted to work even with the most powerful springs, including M170.
Do you want to achieve a higher rate of fire and faster trigger response? Are you planning a power upgrade of your rifle? In that case, you need a MOSFET. It targets the energy from the battery directly to the motor, bypassing the mechanical trigger contacts. As a result, you gain a higher rate of fire of the rifle and a faster trigger response, and the contacts are protected against burn out.
Do you care about realism? Would you like to increase the life of the gearbox? Does your rifle have such a high rate of fire that you are not able to make a single shot? The Active Brake sorts things out. In SEMI Mode, the brake does not allow for compressing a piston after a shot. The piston will stop in the front position which eliminates unnecessary stresses, increasing the service life of the gearbox and its parts. This is important, especially with an AEG power upgrade. After releasing the trigger, the rifle immediately stops firing. So, you gain more realism and, additionally, you do not waste your precious ammunition.
We know how important reliability is on the battlefield. That’s why the unit has thermal protection. In tandem with a time-lag fuse, it fully protects your AEG installation.
Protection against Over-Discharge of the Battery. Modern LiPo and LiFe batteries are very sensitive to over-discharge. If you do not want to damage the battery and you care about its service life, this protection is indispensable. The microprocessor monitors the battery voltage constantly. When the voltage drops down to a critical level, the Controller will not allow firing.
This provides full compatibility with the micro-switches. It is fully resistant to contact bounce. You gain a bigger ROF, a faster trigger response and your MOSFET is less prone to heating.
3RD GENERATION MOSFET
The advent of modern transistors and microcontroller has enabled us to create the smallest and most reliable AEG Controller on the market.
RATE OF FIRE CONTROL
This ensures there is no loss of the rifle’s rate of fire, so you can use stronger LiPo batteries, and still have ROF just like in a real gun.
We know how vital the fast trigger response is during combat. This is why we have developed the Smart Trigger function. It enables you to achieve a faster trigger response. It works with the ROF Control system. During the first shot, the microprocessor sets the ROF Control to 100%. After the first shot, it switches to a previously programmed value (e.g. 50%). As a consequence, the first shot is fired at a full rate of fire, and subsequent shots at a reduced ROF. The best results can be achieved by using a battery with a higher than standard voltage. For example, if you use a 7.4V battery, you can replace it with 11.1V. In this way, you will achieve a faster trigger response with the same rate of fire as with a standard battery. The Smart Trigger is most effective when the Burst time is set at 3 rounds.
Burst mode enables you to make 3-shot series. In this way you can save ammunition and increase the realism. You can change AUTO mode to BURST mode or SEMI* mode to BURST mode. If in SAFE/SEMI/BURST mode you release the trigger earlier, you can make one or two shots. The burst time is set in the menu with accuracy to 4ms. The processor actively compensates for the change in burst time with a decrease in the rate of fire due to battery discharging.
*SEMI to BURST in enhanced mode only
CONFIGURABLE FIRE SELECTOR
The function gives you the option to program your fire selector. There are five modes:
- STOCK WIRING SEMI / AUTO
- STOCK WIRING SEMI / BURST
- MODIFIED WIRING SEMI/AUTO
- MODIFIED WIRING SEMI/BURST
- MODIFIED WIRING BURST/AUTO
You can connect the system to a rifle in two ways. Depending on the selected method, you should set a proper operating mode:
Plug & Play - All you need to do is connect the system between the battery and the rifle.
Enhanced Mode - It requires modification of AEG installation. We connect trigger contacts to MERF 3.2. We can do it using the signal wire attached to the kit.
