MIL STD 704A Standard Test for Airborne Applications

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of MIL STD 704A testing. MIL-STD-704 is an Aircraft Electrical Power Military Standard that defines a standardized power interface between a military aircraft and its equipment.

MIL STD 704A Standard Test for Airborne Applications

The purpose of this standard is to ensure compatibility between the aircraft power system (including external power) and the utility equipment (with connected power supplies). A power source running directly from a generator or AC/DC rectifier must be able to handle various transients from these "dirty" power sources.

Depending on the power type, seven specific power types are defined in the MIL-STD-704 standard:

  • 400Vac at 115Hz (single phase);
  • 400Vac at 115 Hz (three phase);
  • 115Vac variable frequency (360 to 800);
  • 60VAC @ 115 Hz (single phase);
  • 28 volts (DC systems);
  • 270 volts (DC systems).

Power systems compliant with MIL-STD-704 must be able to operate to specification with numerous other disturbances such as input frequency modulation, voltage transients, and possible phase shifts from improper installation. For both 28V and 270V DC sources, it should operate in steady-state voltage ranges with a certain maximum output ripple amplitude and distortion factor, even if surviving the reverse polarity of the input.

In addition, our network solutions are equipped with internal DC-DC and AC-DC power supplies that support the MIL STD 704 standard requirement, making them the best choice for installation on a military tactical platform.
