T238 DTU 1.42 V2 QUALITY Micro Switch Version For V2 Gearbox

The V2 QUALITY is a is a programmable MOSFET electronic trigger system based on the T238 platform, engineered specifically for V2 gearboxes. Featuring full micro switch technology, it integrates intelligent control with comprehensive protection to enhance performance, reliability and versatility.

Comprehensive circuit and mechanical protection includes real-time monitoring of motor/magazine short circuits and MOSFET temperature; automatic battery cell detection with adjustable low-voltage protection; automatic shutdown with alarm during gearbox jams to prevent secondary damage.

Compatible gearboxes:
V2: G&G ARP9, Novritsch SSR4/SSR9, S&T M4, JM9, FB1.0-3.0, Kublai, Jingji, Jiqu etc.

Key Features:

Dimensions: 45×30×14mm
Operating voltage: 6-16.8V
Max current: Startup 300A, Braking 85A, Magazine 30A
Full micro switch for detection
Motor short circuit/MOSFET overheat/Battery over-discharge/Gear block-up protection
Programmable auto-loading duration and multiple firing modes
Active brake technology for instant piston stopping

Functions:

Motor Short Circuit Protection: Automatically cuts power to motor when short circuit is detected, with LED flashing alert. Immediately disconnect battery for troubleshooting.

MOSFET Overheat Protection: Activates when MOSFET overheats - gearbox won't fire when triggered, motor emits one "Beep!", system resumes after cooling.

Battery Over-discharge Protection: Auto-detects cell count, default cutoff 3.2V/cell. When triggered, motor emits "Beep! Beep! Beep! Beep!" then enters sleep mode. Replace/charge battery promptly.

Gear Block-up Protection: Cuts motor power and emits elongated "Beep~" during gearbox jams. Immediately disconnect battery and inspect gearbox/gears.
Auto-Loading: When magazine is inserted, the system automatically powers the magazine motor to run independently for few seconds, achieving auto-loading to prevent dry fire on first shot. Loading duration can be set via Programming Option 9.

Active Braking: Utilizes excess energy from the motor to stop inertial rotation, promptly halting the piston and eliminating gear over-rotation. Prevents semi-auto becoming full-auto issues. Most effective with high-torque motors.

Multiple Fire Modes: Semi-auto/Full-auto/Burst/Binary-trigger/Sniper Delay. Program fire modes for each selector position through programming mode.

Pre-cocking: Only active in semi-auto mode. Delays motor braking to stop piston near rear position, pre-compressing spring. On next shot, gears only need minimal rotation to release piston, significantly improving trigger response.

Adjustable ROF: In full-auto mode, adds delay between cycles to control motor speed, achieving adjustable rate of fire.

Firing Modes:

Safe：Functions same as factory. Trigger is immobilized by safety lever - retain this lever during installation.

Semi-Auto：Programmable for standard semi-auto, binary trigger, or 3-6 round burst. Default: standard semi-auto.

Full-Auto：Programmable for full-auto, 3-round burst, or 4-6 round burst. Default: full-auto.

Binary Trigger: Gearbox fires once on trigger pull and again on release.

Sniper Delay: Simulates bolt-action rifle cycling. Requires waiting period between shots before system responds to trigger.

Selector Type: G36 and AK47 replicas may have reversed semi/full-auto order. Use this setting to match your replica's configuration.
