Perun ETU++ chip (T-Deans)

Perun ETU++ circuit

ETU++ is a replacement of the standard electronics in G&G replicas equipped with the ETU system. It enriches the replica with many new, useful functions. All you need to do is unplug the factory electronic board located in the stock and plug in the ETU++. The factory contacts in the gearbox are retained, so there is no need to open it.

Works with any replica equipped with the ETU system from G&G, as well as with 7.4V, 11.1V and 14.8V Li-Po batteries.

Functions of the system:

-Programmable fire modes -Single, series or automatic fire can be set at any selector position (except "protected").
-Active brake -Stops the motor after each shot, preventing spring compression and overspin.
-Precocking -The plunger will remain in the rear position after each shot, ensuring that the shot is fired as soon as the trigger is depressed. To release the spring after using precocking, depress the trigger and hold it for 2 seconds.
-Binary trigger - Allows you to easily fire double shots in single-fire mode. When enabled, single shots will be fired not only when the trigger is pressed, but also when the trigger is released.
-Reduced rate of fire
-DMR Mode -Institutes minimum intervals between shots to meet the requirements for DMR replicas at certain competition venues.
-Low Battery Alert -If the battery voltage drops to a dangerously low level, the user will be notified with short beeps repeated every minute.
-Diagnostic System Continuously checks the status of the electronics and the replica. In the event of a problem, it will immediately provide information on what might have caused it, making it easier to rectify the fault.
-Electronic fuse -Protects the replica and the battery in a serious malfunction. It will automatically disconnect the battery if a short circuit is detected or a jam occurs in the gearbox.

All settings are changed using only quick and easy to remember combinations of fire selector and trigger movements. The system communicates with the user via audible signals and a multi-coloured LED.

The Polish company Perun entered the ASG market in 2016. Thanks to the use of high-quality materials, well-thought-out designs, quality control constant contact with players and service technicians, the manufacturer offers Mosfet and ETU systems from the top shelf.
