SECTION 1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The True Blue Power TS6 Emergency Battery Power Supply part number 6430006 is designed to
supply DC power for emergency equipment after aircraft power failure occurs. During normal
aircraft operation, the TS6 Emergency Battery Power Supply (EBPS) will utilize the aircraft’s power
to recharge or maintain existing charge at full capacity. The TS6 is a sophisticated power system
that utilizes NiMH cell technology which provides improvements in performance, safety, life, and
weight when compared to traditional or competing backup systems. Consideration given to key
electrical and mechanical design principles yield compliance with regulatory standards and meet or
exceed industry expectations. The TS6 is a complete EBPS that provides significant value and
benefit to an aircraft designer, owner, and operator.
The TS6 requires professional use and maintenance to deliver maximum performance and value
as designed. This manual contains information related to the specifications, installation, operation,
storage, scheduled maintenance, and other related topics associated with the proper care and use
of this product.
1.2 PHYSCIAL ATTRIBUTES
The TS6 consists of a rugged metal chassis with a DB9 style connector for electrical interface, and
a permanently installed rechargeable battery. The unit is designed to be mounted with four 6-32
screws to the aircraft structure.
1.3 UNIT ARCHITECTURE
The unit has four primary functional features:
Power pass through
Internal cell charging.
Cell state of charge gauging
Consistent standby output voltage
The unit passes through normal 28V power, while maintaining internal power storage with internal
battery charge and discharge control. The unit input provides a regulated 24V output in the event
of loss of input power. Additional functions include analog state-of-charge, 80% capacity dispatch
test, and discharge shutdown. All battery management functions are handled internally, including
protection against safety considerations such as short circuit, over temperature, under voltage, and
over voltage conditions.
