EMITTED VOLTAGE SPIKES TEST
Voltage Spike Test
MIL-STD-1275 (Characteristics of 28 Volt DC Input Power to Utilization Equipment in Military Vehicles) defines a set of
test procedures intended to verify the power-input requirements of electronic equipment used in military platforms and to
demonstrate robustness against electrical transients. One of these procedures is the voltage spike test.
The voltage spike test is performed to evaluate the immunity of onboard electrical/electronic equipment to abrupt voltage
excursions that may occur during engine start, alternator/battery switching events, or other operational conditions. During the test,
the output of the vehicle power source (battery or alternator) is increased in a controlled manner to represent a transient event, and
the equipment response is monitored to verify continued functionality and the absence of degradation or damage.
Purpose Objective
- Define and verify power-input requirements for electronic equipment used in military systems.
- Demonstrate protection and immunity against voltage spike events.
- Ensure onboard electronic equipment remains intact and operates correctly under transient conditions.
Test Scope Scope
- Simulation of abrupt voltage excursions that may occur during engine operation or due to other onboard events.
- Controlled increase of the output from the vehicle battery or alternator and measurement of equipment response.
- Monitoring of equipment operational status and observation of any damage or performance degradation during and after the exposure.
Technical Implementation Process
- The applicable spike waveform and test conditions are defined in MIL-STD-1275 (revisions D/E/F) and are applied at the specified DC input levels for the platform.
- During the test, the output of the vehicle power source (battery/alternator) is increased in a controlled manner to represent the transient event, and the equipment response is measured.
- Equipment performance is monitored throughout the exposure and inspected for any functional anomalies, damage, or degradation.
Application Areas Use Cases
- Verifying that onboard electronics in military vehicles are protected against voltage spike events.
- Ensuring electronic equipment remains reliable and operates correctly under transient power conditions.
- Supporting qualification and compliance activities under MIL-STD-1275 D/E/F test procedures.
