Load Banks

Fairchild AFB, WA

1. BACKGROUND: The project entails the acquisition of four essential load banks to facilitate the testing of ground power units (GPUs) for KC-135 aircraft maintenance. Load banks, in this context, serve as devices that mimic the dynamic electrical load variations encountered during aircraft maintenance, verifying that GPUs can handle diverse loads reliably. Regulatory compliance is paramount, ensuring that GPUs adhere to airworthiness standards for military aircraft maintenance. This initiative is pivotal for safety, preventing unexpected failures and complying with aviation regulations. It aligns with broader aircraft maintenance systems, integrating seamlessly with ground support equipment (GSE). The load banks will play a crucial role in enhancing the overall safety and reliability of maintenance operations. Key features include the ability to simulate load variations and real-time monitoring capabilities. The integration of load banks into routine maintenance checklists ensures systematic testing, while data logging provides valuable performance metrics for analysis and predictive maintenance planning.

2. OBJECTIVES: The primary objective is to ensure the safe and efficient upkeep ofKC-135s by subjecting GPUs to simulated electrical loads during testing.

3. REQUIREMENTS: The contractor shall provide four (4) Ll00D load banks with the following salient characteristics:

a) 400hz Aircraft connector

b) 28V Transformer

c) Digital Meter to measure volts/amps/frequency/kw/power factors

d) Power indicator lights

e) Thermal protections

f) Phase rotation indicator

g) E and F circuit indicators

h) Carrying case with wheels and handle

i) Nominal Voltage is 200v

j) Levels of the load are discrete

k) Needs to be portable (current style is a portable 'suitcase' style which is ideal - 22in L x 8in W x 16.5in H. approx 45lbs)

l) Minimum required Watt Absorption Range: 10kW-109kW
