MIL-STD-1275 Characteristics of 28 Volt DC Electrical Systems in Military Vehicles

Developed by the US Department of Defense, the MIL-STD 1275 standard is an immunity standard that defines a set of test conditions to be applied to the input of a 28V electrical power system inside a military vehicle. These include spikes, surges, operating voltages and surges.

This standard defines test methods for a device to be used or an equipment to be installed in a military vehicle. According to these test results, it is determined whether the device or equipment meets the standard requirements.

The main tests performed under the MIL-STD 1275 standard are:

  • Radiated voltage peak
  • Radiated voltage fluctuations
  • Injection voltage peak
  • Injected voltage fluctuations
  • Operating voltage range
  • reverse pole
  • Start-up
  • voltage fluctuation

The best way to guarantee compliance with the MIL-STD-1275 standard in a direct current power system is to use a proven input protection module. Such modules are designed to immunity standards that protect against surges and spikes and include a filter to control electromagnetic interference.

The MIL-STD-1275 standard does not see electromagnetic interference and electrostatic discharge within the scope of the standard, but still most of the requirements are centered around electromagnetic interference and electrostatic discharge phenomena.

The goal of this standard is to ensure compatibility between the vehicle power system and the utility equipment, without unnecessary restrictions on the power supply, using equipment that cannot tolerate military vehicle power electrical incidents.

First published in 1976, this standard specifies various requirements for power supply steady-state conditions, spikes, surges, and surges, complementing the requirements contained in the MIL-STD-461 standard of the power system and usage equipment. This standard has seen many revisions in the following years. The MIL-STD-1275 standard is accepted as a complement to the MIL-ST-461 standard.

Within the framework of this standard, the general requirements are organized under the following headings:

  • temperature conditions
  • Circuit characteristics measuring point
  • Tested electrical device compatibility
  • Polarity
  • cargo warehouses
  • battery status
