The EPS Power Unit contains the brain of the system, DTI (DigitalTech Intelligence) as well as the battery pack. This is the heart, brain and power behind the Campagnolo electronic drivetrain. The DTI's main functions are monitoring and managing the battery pack, enabling and monitoring the derailleurs, signalling any problems via the LED or buzzer and communicating with the EPS interface. Once it has received digital signals from the interface, the Power Unit use a special algorithm to process them and translates into movement of the derailleurs. The DTI, housed inside the Power Unit, continuously monitors the signals that arrive from the interface and the derailleurs, managing their operation.
The Power Unit, along with the interface, also acts as the diagnostic centre of the system, signalling any problems in the system via an LED and acoustic buzzer in the Power Unit. Campagnolo deliberately housed all the system electronics inside the Power Unit, making the system less vulnerable to external contaminants (such as oil, water, mud and dust) and make it reliable even when subjected to significant vibrations, such as those generated by professional riders on events as extreme as Paris-Roubaix. By using this design philosophy the chances of any failures in the system are dramatically reduced and is guaranteed to function even in the most extreme weather or road conditions. To further protect the Power Unit, the housing for the Battery Pack has been produced from a self-extinguishing plastic material. The DTI is equipped with a number of input/output data ports which allow you to check the system remotely and even update the Firmware and EPROM. The battery uses Lithium Ion technology and has an unprecedented battery life. The fully-charged system operates at values of 11.1 nominal Volts (a capacity of 950mAh) and 12.6 maximum Volts. The battery life depends on how much the system is in use or on stand-by. In stand-by mode the system is able to maintain the charge for up to 6 months, at the end of which the red LED will signal that the battery requires charging. To avoid damaging the battery pack, the system turns off automatically when it reaches 9 Volts. If it reaches 7.2 Volts, a special circuit inside the battery pack (PCM) turns the battery pack off to avoid absorbing additional energy. When the charge has dropped to this level and the LED is off, it is advisable to recharge the battery to avoid damage to the system. It is advisable to recharge the system at least every 6 months to avoid the battery going flat. Weight: TBC
