Campagnolo EPS Power Unit -

After twenty years of research, Campagnolo developed an unrivaled electronic shifting system; it built the Campagnolo EPS Power Unit to house the brains and power source of the system in a case that protects these vital elements from everything under the sun.

Digital Tech Intelligence (DTI) is the brains of the entire Electronic Power System (EPS), and performs the most important operations in blisteringly fast time. For movement operations, DTI is in constant communication with the EPS Interface, receiving digital signals from the Super Record 11 EPS Shift Levers, processing them through unique algorithms, and translating that information into the movements for the front and rear derailleurs. Concurrently, DTI is checking and maintaining onboard diagnostics, managing and checking the charge status of the battery pack, and controlling all derailleur automatic correction functions. Impressed yet? It does more. DTI is the fail-safe against all system anomalies in EPS, signaling warnings through an acoustical buzzer on the undercarriage of the Power Unit and transmitting signal to the EPS Interface, which communicates the information to you through a detailed RGB-variant color coding system. It also relays a message upon resolution of any system anomaly.

As mentioned, the EPS Power Unit also houses the Battery Pack that powers the Digital Tech Intelligence. The lithium ion Battery Pack holds a charge longer than any electronic shifting system battery in production. In Standby Mode the Battery Pack can retain a charge for six months. In use, the charge autonomy varies by type of usage. At opposite ends of the spectrum, a 310 mile-per-month rider can expect around 964 miles per full charge, whereas a 1242 mile-per-month monster can expect roughly 1260 miles per full charge. Just as the DTI acts as a fail-safe for system anomalies, the Battery Pack has its own failure-prevention system to protect EPS and the battery. Operating at full charge from 11.1 nominal volts to 12.6 maximum volts, the system takes precaution at nine volts and turns itself off. Campagnolo exercised further precaution by installing a special circuit called PCM within the Battery Pack that turns off all charge when the Battery Pack reaches 7.2 volts.

Just as a helmet protects the brains of its user, the cover of the Campagnolo EPS Power Unit is designed to protect the brains of its electronic shifting system. The 'black box' of componentry, it is an ultrasonic welded housing unit made of a self-extinguishing fireproof thermoplastic called UL94 V0. Campagnolo added special dampening to the case to minimize terrain vibration, and took the additional step of incorporating an anti-vibration dampening plug on the rear of the EPS Power Unit. Campagnolo created a brilliantly basic bracketing system that lets you choose where to place the EPS Power Unit on the frame. The EPS Power Unit is also IP67 compliant, a rigid international standard for electronics that requires protection of electronic components from water and dust alike. To give you an idea of how stringent this test is, every Campagnolo EPS component had to operate perfectly while submerged under water for 30 minutes.

Campagnolo went overboard designing a Power Unit capable of withstanding any torture thrown at it. Whether it's from the road, the weather, or the Father Time, the EPS Power Unit is prepared to deliver unparalleled performance without missing a beat.
