ACT is proud to offer MIL-STD-704 products. MIL-STD-704 power supplies are aircraft power supplies that meet the requirements called out in MIL-STD-704. Not all power supplies meet this, which is often required for US military aircraft, and it is a sure sign of performance you can trust when seeking power supplies for your own applications.
What Is MIL-STD-704?
According to MIL-STD-704, the purpose of this interface standard is to ensure compatibility between the aircraft electric system, external power, and airborne utilization equipment and establishes the requirements and characteristics of aircraft electric power provided at the input terminals of electric utilization equipment. It is a required standard created by the U.S. military.
- AC systems
- 115/200 volts at 400 Hz
- 115/200 at 60 Hz (COTS only)
- 115/200 volts varying from 360 to 800 Hz (known as variable frequency source)
- 230/400 volts at 400 Hz (known as a double-voltage system)
- DC Systems
- 28 VDC
- 270 VDC
Some of the input steady state characteristics with set limits, according to the MIL-STD-704 standard, are:
- Steady state voltage (AC and DC Systems)
- Voltage phase difference (AC Systems)
- Voltage modulation (AC Systems)
- Voltage unbalance (AC Systems)
- Crest Factor (AC Systems)
- Steady state frequency (AC Systems)
- Frequency modulation (AC Systems)
- DC component (AC Systems)
- Distortion factor (AC and DC Systems)
- Distortion spectrum (AC and DC Systems)
- Ripple amplitude (DC Systems)
Also included are transient characteristics like:
- Peak voltage (AC Systems)
- Frequency transient (AC Systems)
- Voltage transient (AC and DC Systems)
Other topics the MIL-STD-704 standard covers include abnormal operation, emergency operation, and load characteristics for both AC and DC power systems.
It’s no easy task for a product to meet MIL-STD-704. These products must prove they can function effectively under extreme conditions, and customers may subject them to a variety of different tests to see how well they hold up and how those conditions affect them. Once a product passes this vigorous testing, you can be confident it will work for you as promised and stand up to the harshest conditions you can subject it to, whether you are interested in military or private sector applications for your MIL-STD-704 power supply product.
