- Microprocessor control system
- Quick setup using a software utility for specific batteries
- Battery parameters registration in non-volatile memory
- Registration of not only the battery charge current, but also the discharge current
- Low internal consumption at idle
- Full compatibility with the system of advanced diagnostics of the electric train
- A typical range of pre-set factory charge profiles adapted to specific batteries used on rolling stock
- Low charge voltage and current ripple factor
- Rolling stock mechanical and climatic design
- Battery protection against deep discharge
- Battery overheating protection
- Full-scale indicating system
- Modern and convenient combined sensor for measurement of battery current and temperature
- Function of emergency power on from the discharged battery to start the electric train
- Before being sent to the customer, the charger goes through a full cycle of factory tests
- The solution has been developed on the rolling stock of Russian Railways
