X-ASR – 4th Gen Mosfet Set

X-ASR is the world’s first 4th generation MOSFET protected against reverse polarity. It saves space, time and money because additional regular fuse is no longer needed. Acting as an electronic guard, X-ASR improves your AEG’s safety and durability through conformal coating and self-test with 2 LEDs. Although designed for up to M120 springs, in case of high torque motor and gears you can use stronger spring.

What makes X-ASR so special?
No additional fuse required in AEG installation
Automatic resettable protection against reverse polarity – protects motor and the MOSFET itself in the event of reverse polarity. Reverse connection will not damage the MOSFET or motor; the AEG will work again once you connect the battery in the right way.
Smart fuse – protects MOSFET in case of motor jam. It prevents from overheating, overloading and overcurrenting. The MOSFET is protected against short circuit of signal and motor wires. In case of too strong AEG configuration, the smart fuse will turn off the MOSFET in order to prevent overheating.
Built-in self-test – 2 LEDs allow for quick troubleshooting
Conformal coating – Military Specification MIL-V-173C provides resistance to difficult atmospheric conditions

What are X-ASR’s biggest assets?
Mosfet – targets energy from the battery directly to the motor, bypassing the mechanical trigger contacts. As a result, your rifle gains higher rate of fire as well as faster trigger response. Moreover, trigger contacts are protected against burnout.
Debouncing – provides full compatibility with micro-switches and ensures complete resistance to contact bounce (vibration). Your AEG gains higher ROF, faster trigger response and your MOSFET is less prone to overheating.

What is your AEG protected from when having X-ASR?
Simple motor jam consequences – after a motor jam, the MOSFET will not be damaged due to too high current or overheating
Damage resulting from battery reverse polarity – since R/C mini-tamiya connector has different polarity than the airsoft one, lack of experience or precaution while connecting the battery will cause no damage to it
Consequences of using weak NiCd/NiMH batteries – the MOSFET will not be damaged due to too low voltage
Damage to insulation of AEG installation and short circuit
Harms caused by poor weather conditions

Behind the lines
Considering its functions, X-ASR is an improved version of NanoASR MOSFET. However, when designing X-ASR, we focused even more on its reliability.

The most important assumption was that it must be installed without any additional fuse. All the other MOSFETs we offer require supplementary fuse in AEG installation. To eliminate such necessity, we implemented the smart fuse and protection against reverse polarity in X-ASR.

Get ready for these amazing functions:

SMART FUSE

We have developed an electronic fuse with an accurate current sensor. A combination of current, voltage and temperature measurements makes your AEG installation highly reliable. It protects the MOSFET against overheating, overloading and short-circuiting. If your airsoft gun becomes jammed, the function protects the motor and battery against damage.

MOSFET

Do you want to achieve a higher ROF and faster trigger response? Are you planning a power upgrade of your gun? 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 ROF of the gun and a faster trigger response.

DEBOUNCING

This provides full compatibility with the micro-switches. It ensures full resistance to contact bounce (vibration). You gain a bigger ROF, a faster trigger response and your MOSFET is less prone to overheating.

BUILT-IN SELF-TEST

This allows you to quickly check whether the device is working properly. It helps to locate where the problem lies when anything goes wrong.

COATING

Thanks to its special conformal coating, our product is resistant to atmospheric conditions (Military Specification MIL-V-173C).
