APS finally released their first Electronic Gear Box, named eSilver Edge Gear Box. A micro chip (Super Dynamic Unit) S.D.U.™  that works together with magnet gears set, reinforced piston, quick change spring guide and micro switch trigger that gives you instant trigger response when shooting.

Base on our design and testing, eSilver Edge Gear Box works perfectly under 7.4v to 12.5v. The current are always stable at <11 Amps in any voltages between 7.4v to 12.5v. Low and stable Amps means it drains less battery and the lifespan of the components could last longer.

The S.D.U.™ chipset that used in eSilver Edge Gear Box has a unique function that stop the gearbox from further damage if electric current is too high. Simply to say, electric current / Ampere will increase if there is a malfunction inside the gearbox. For instant, bad motor, damaged gears or short circuit. When our S.D.U. detected more than 5 trigger presses in exceed Amps, the whole gearbox will shut down to prevent further damage. User has to disconnect and then reconnect the power supply to reboot the gearbox, we strongly recommended user to check the internal immediately if mal-function happened.
