The TTU-4530
™ is designed to operate in environments typically encountered by fleet vehicles,
including wide temperature extremes, voltage transients, and potential interference from other vehicle
equipment.
To ensure proper operation in such an environment, the TTU-4530
™ was subjected to standard tests
defined by the Society of Automotive Engineers (SAE). The specific tests included temperature, shock,
vibration, and EMI/EMC. These tests were performed by independent labs and documented in a
detailed test report. In accordance with Appendix A of SAE J1113 Part 1, the Unit is considered a
“Functional Status Class B, Performance Region II” system that requires Threat Level 3 Testing.
The following shows the environmental conditions the TTU is designed to operate in and the relevant
SAE tests that were performed. No formal altitude tests were conducted.
