Introduction
This Technical Specification defines characteristics and interfaces for electric onboard power supply
systems. The following European Standards and Technical Specifications refer to the defined target
energy supply system in this present Technical Specification:
CLC/TS 50535 Railway applications – Onboard auxiliary power converter systems
(Auxiliary converter interfaces applicable for the different options defined in
the target system architectures)
1)
EN 50533 Railway applications – Three-phase train line voltage characteristics
(Characteristics of the voltage system used for auxiliary power supply)
2)
EN 50546 Railway applications – Shore (external) supply system for rail vehicles
(Interface description of the shore supply including protection functions)
2)
EN 50547 Railway applications – Batteries for rail vehicles
(Standardized batteries for rail vehicles and charging characteristics)
CLC/TS 50537 (series) Railway applications – Mounted parts of the traction transformer and
cooling system
(Standardized products used in conjunction with traction transformers and
traction cooling systems)
CLC/TS 50534 has to be understood as a basic document of a set of hierarchically structured
specifications. This set of European Standards and Technical Specifications defines a consistent
technical framework beginning on an architectural level, followed by standards belonging to important
system interfaces and concluding this hierarchy with Technical Specifications on component level. The
diagram in the foreword points up these different system integration levels and shows the
dependencies between the documents.
One main objective of this standardisation initiative is to simplify the cooperation between concerned
railway stakeholders in charge of operating onboard auxiliary power systems, designing systems able
to cope with the operational requirements and stakeholders manufacturing auxiliary power system
components, which provide the requested services.

1 Scope
This Technical Specification defines characteristics and interfaces for electric onboard power supply
systems. It applies to locomotive hauled passenger trains and electric multiple units with distributed
power as well as trains with concentrated power for main-line application.
The objective of this Technical Specification is to define target systems, as regards the following
interfaces and characteristics in order to enable further standardisation:
• interface between traction system and auxiliary power supply system;
• train line type: voltage, frequency and number of poles;
• interface between auxiliary power supply system and battery system;
• interface of the auxiliary power supply system as well as the low voltage grid to a shore supply
(stationary workshop supply or external supply);
• supply concepts for essential loads e.g. HVAC systems and battery chargers;
• redundancy concept within the supply systems;
• auxiliary load control and protection strategy at train level.
Described system and interface characteristics define the technical basis for dependent European
Standards and Technical Specifications. The introduction of this Technical Specification shows this
dependency to adjacent documents.
Starting from a generic functional description of electric onboard energy supply systems structured in
line with EN 15380-4 and a description of the related vehicle concepts, generic system architectures
are derived, which are illustrated by examples of consistent sets of system designs showing interfaces
and dependencies among concerned subsystems.
Relevant train configuration and concerned energy supply subsystems in scope of this Technical
Specification are defined in Clause 4.
