Scope and field of application
Used to supply power to relay AI and ALB systems housed within interlocking tower modules and EI towers, level-crossing signalling system equipment in LCE modules, as well as communication devices, local control and supervisory systems, and utilities, including lighting, air conditioning, fire extinguishing and access control systems. Designed for use with single-phase external power sources.

Used to supply power to relay AI and ALB systems housed within interlocking tower modules and EI towers, level-crossing signalling system equipment in LCE modules, as well as communication devices, local control and supervisory systems, and utilities, including lighting, air conditioning, fire extinguishing and access control systems. Designed for use with single-phase external power sources.
Main features
- connection to no less than two external powersources;
- automatically switching from one external power source to another whenever the power disappears or no longer meets the voltage requirements;
- galvanic isolation of signalling equipment loads from external power supply devices;
- guaranteed load power supply;
- continuity of power supply loads connected to the UPS for a specified duration of time from batteries, when switching to a different external power supply or when disconnecting them;
- automatic and manual switching of power supply devices for signalling system equipment, bypassing inverter;
- indication and transmission of status information to TDMS and remote-control machines.
