New certifications for True Blue Power emergency power supply

WICHITA. — True Blue Power has received several FAA Supplemental Type Certificates (STCs) for the TS835 Series lithium-ion emergency power supply (EPS).

True Blue Power received a Part 25 STC for installation of the TS835 Series in LearJet 35/36 models and a Part 27 STC for installation in BK117 and EC145 helicopters. The company amended a Part 23 Approved Model List (AML) STC to include more than 20 aircraft models, including the Beech King Air and Pilatus PC-12.

“The new and amended STCs provide service centers with an easier and more efficient certification path for the installation of our lithium-ion power supplies,” explained True Blue Power’s director of sales Tom Genovese. “Combined with the product’s advanced design, the STCs add to the unit’s overall lower cost of ownership.”

Through the Part 23, 25 and 27 STCs, the TS835 Series is now approved as a direct replacement for the J.E.T. PS-835 and PS-855 lead-acid batteries. The power supply utilizes the same rack, connector, wire harness and OFF/ARM/TEST switch as the PS-835 and PS-855. In most cases, the installation just requires removing the original battery and inserting the TS835 into the existing 1/4 ATR mounting rack, company officials said.

Additionally, the TS835 Series received European Aviation Safety Administration (EASA) Technical Standard Order (TSO) certification in December 2012. True Blue Power now holds FAA, EASA and Transport Canada certifications. “We are pursuing several EASA STC approvals for both OEM and aftermarket installations,” stated Genovese. “We are paving the way for service centers around the world to install True Blue Power products.”

The TS835 Series Emergency Power Supply provides 24.5 VDC power for critical and standby equipment and maintains full capacity by recharging during normal flight operations. The EPS utilizes lithium iron phosphate technology, which offers advantages over lead-acid chemistry, company officials said. A 63% weight savings contributes to payload efficiency, while the improved life expectancy is more than double that of legacy products, officials add.

The TS835 Series is available from approved avionics dealers and the following True Blue Power distributors: Adams Aviation Supply Co., Aviation Partner Group, Inc., Avionics International Supply, Avionik Straubing GmbH, Dallas Avionics, EDMO Asia Pacific Pty.
