Digital trigger unit DTU, PRO, gearbox V3, T238

Digital trigger unit DTU, PRO, gearbox V3, T238. Fully optical trigger unit DTU V3 PRO Light Sensor from T238 for gearbox version 3. Professional version of DTU with two powerful MOSFET switches and two trigger optical sensors that can set the exact sensitivity of the trigger and AUG mode (half-pull semi, Full-auto trigger). Specially designed ETU (Electronic Trigger Unit) for airsoft guns, Gel Ball Blasters and other standard V3 gearboxes with semi-automatic (Semi-auto) and fully automatic (Full-auto) firing modes. The fully optical processor unit can effectively improve the response to the trigger pull, the overall stability of the weapon and the rate of fire (ROF). This product is designed by the manufacturer for springs weaker than M150, requires soldering and professional wiring. It is therefore recommended that the installation be carried out by an experienced technician at an authorized service center.

Function of DTU V3 PRO Light Sensor:
Li-pol Support: A four-cell battery with a voltage of up to 14.8V can be used.
Short circuit protection: When a short circuit is detected in the motor/magazine circuit, the system will cut off the power supply to the motor/magazine and notify with a flashing LED. Disconnect the battery and solve the problem.
Programmable shooting mode: You can set the binary trigger, Burst 3-6 BBs, trigger sensitivity, AUG mode, rate of fire, choose the lower limit of the battery voltage, the delay between shots, G36/AK type switch, etc.
Auto-loading function: Designed for gel blaster magazines with a motor inside. When changing the magazine, the motor in the magazine automatically starts for 0.5 seconds.
Preload: The initial position of the piston is adjustable in semi-automatic mode thanks to the delayed braking. The pre-piston function can reduce the shot delay and increase the trigger response speed.
Overheat protection: When the MOSFET is overheated, the motor will beep when the trigger is pressed. This will continue until the MOSFET automatically restarts after cooling down.
Low voltage protection: The default setting is for a 7.4V battery. Replace the battery when you hear 4 beeps as a low voltage warning sound.
Active brake: Prevents the large inertia of the gear wheels. Solves the problem of multiple shots per trigger pull (applicable to fast gears or high battery voltage). The maximum spring release (piston in the front position) can be achieved, and the parts in the gearbox are thus less stressed. The effect of the active brake is especially significant for a high torque motor.
Block-up protection: When the wheels lock up, the gearbox stops working and the DTU emits a long beep. Immediately disconnect the battery and resolve the problem.
Programming: By setting the switch to the SEMI position and holding the trigger (10s), you will access the programming menu.
