Product Details
✓Perun ETU++ Mosfet replaces the G&G Armament OEM Mosfet featured in G&G's Mosfet Integrated Gearbox (MIG) seen on the G&G ARP9 Series, FAR556, CM16 Raider 2.0E, and many others. ETU++ can be easily installed without ever opening the gearbox! Simple wiring to replace the OEM triggerboard located in the battery compartment. IMPORTANT: ETU++ is only compatible with G&G AEGs that have a pre-installed ETU Triggerboard.
✓Programmable Firing Modes with independent select fire modes allowing safe, semi, burst or auto firing on both selector positions. Reduce the rate of fire in automatic or burst fire to save ammo or make the AEG shoot in a more realistic fashion or Adjust intervals between semiautomatic shots to comply with DMR rules on some fields.
✓Programmable Binary Trigger Mode for easy double shots in semi auto which allows a single shot to fire followed by an additional shot after trigger release.
✓Active Brake mode which stops the motor after each shot, preventing spring compression or in case of models with high ROF / overspin issue.
✓Low Battery Alarm Dedicated for Li-Po and Li-Ion batteries. When the battery voltage falls to a low level, the user will be notified by short sound signals that are repeated every minute. This may also be freely switched on and off.
✓Built in diagnostic system that provides LED feedback so you can easily monitor the status and immediately troubleshoot any issues when they occur with LED color indicators.
