True Blue Power has introduced the company's new TS28 emergency battery power supply (EBPS). Designed for a 28V electrical bus, the TS28 provides DC power for aircraft loads, such as emergency lighting and critical equipment in the event of main aircraft power failure. It is a direct replacement for radiant battery power supply (CBS28-1) on Citation 550, 560, 650, 680, 680A and 700 aircraft.

The TS28 reduces costs for aircraft operators by delivering superior quality, longer life and easy field replacement of the unit's battery pack. Benefits of the TS28 on Citation aircraft include: longer life: four to six years battery pack life; reduced maintenance costs: two-year capacity check; higher battery capacity; no memory effect; and is field-replaceable.

The True Blue Power TS28 features nickel metal hydride (NiMH) battery technology. This offers improved performance, battery life and more energy per cell compared to competing battery chemistries, including nickel cadmium (NiCad). The TS28 is more environmentally friendly and provides significantly better dispatch reliability, with no memory effect and increased capacity.

The TS28 is easy to install and designed with a rugged, metal chassis and four-pin Mil-Spec, circular-style connector for electrical interface. Only four threaded fasteners are needed for installation. The easily removable, rechargeable battery pack shortens maintenance timelines and extends product life. The TS28 features a two-year maintenance cycle with a full charge and discharge capacity check.

True Blue is also bringing out a new main ship battery during the New Product Introduction session at this week's Aircraft Electronics Association (AEA) International Convention and Trade Show in Dallas, Texas. The new Gen5 TB50 lithium-ion aircraft battery is a 50 amp-hour, engine-start battery. Its dimensions are equivalent to the industry standard 44 amp-hour battery, while offering more power, less weight and zero maintenance. The TB50 provides aircraft owners and operators a direct path to a lithium battery upgrade, with all the benefits the advanced technology offers.

The TB50 weighs 50 per cent less and delivers more amp-hours per pound than lead-acid and NiCad alternatives. It provides more power for engine starts, more energy for emergency and back-up power and ultra-fast recharge. It eliminates expensive battery maintenance and frequent, costly capacity checks.

With an eight year useful battery life, The TB50 offers up to four times longer battery life than lead-acid and three years longer than NiCad batteries. It communicates real-time state-of-charge (SOC) and state-of-health (SOH) data to the cockpit. Field-programmable parameters enable charge current limiting and alerts for end-of-life, minimum dispatch capacity and engine-start readiness.

The TB50's battery status indicator provides SOC, battery mode and health data without the need for aircraft power or external test equipment. It also addresses the negative environmental impact of heavy, lead-acid and NiCad batteries. It eliminates toxic metals and acid spills, and significantly reduces carbon emissions. All True Blue Power lithium-ion batteries can be recycled or disposed of in area landfills.

The TB50 is certified to TSO-C179b, RTCA DO-311A, RTCA DO-160G and RTCA DO-178C Design Assurance Level A. The battery delivers superior reliability and performance. It is ideal for use in rugged environments and outperforms all other aircraft batteries in extreme temperatures.
