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 full auto mode, X-ASR cooperates even with M150 spring. Moreover, in case of high torque motor and gears you can use stronger spring.
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.
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.
Quick test feature allows you to quickly check if the device is working properly. It helps to locate where the problem lies if anything goes wrong.
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
