What It Evaluates

Test at maximum duty cycle using 14, 28, or 270 Vdc, or 115/230 Vrms AC. Voltage tolerance is ±1% at 100 V or above and ±2% below 100 V; transition times must remain below 1.5 ms.

Equipment Categories:

• A(CF), A(NF), A(WF): Constant 400 Hz, narrow 360–650 Hz, or wide 360–800 Hz AC power.
• A, B, D, Z: Transformer-rectified 28 Vdc, battery-supported 14/28 Vdc, 270 Vdc, or other 28 Vdc systems.
• H, L, P, I, R: Additional harmonic, current-modulation, power-factor, inrush, or DC-ripple designations.

When It Applies

Applicability depends on the airborne equipment installation, declared category, aircraft environment, and program requirements.
