Scope and field of application
This device is used to provide uninterruptible power supply to relay, hybrid and computer-based interlocking systems, as well as other computer-based, electronic and relay signalling system equipment.
UBP-AT reliably provides an uninterruptible supply of three-phase alternating current with the required voltage to signalling system equipment. The device is designed to ensure that any equipment connected to the uninterruptible power supply system will be powered for a specified duration of time from batteries, when switching to a different external power supply or when disconnecting them.

Advantages
- working in three-phase power supply systems while supplying uninterruptible three-phase power to signalling systems;
- modular structure of rectifier-inverter blocks;
- possibility to foresee the N+1 redundancy of power supply modules;
- possibility to hot swap power supply modules;
- flexible system configuration;
- possibility to increase the output power of UBP-AT through additional rectifier-inverter modules;
- automatic and manual bypass;
- UBP-AT status information is transmitted via a relay interface, Ethernet interface with the SNMP protocol (to the computer-based interlocking system), RS-485 interface with the Modbus RTU protocol (to the technical diagnostics and maintenance system (TDMS)).
