INJECTED VOLTAGE SPIKES TEST
Injected Voltage Spikes Test
The MIL-STD-1275 D/E/F series, which defines 28V DC input power characteristics for equipment used in military vehicles, is applied to verify the compatibility of electrical equipment with vehicle power sources. MIL-STD-1275 D/E/F includes the Injected Voltage Spikes Test to evaluate the robustness of onboard electronic equipment against sudden voltage variations that may occur while the vehicle engine is running and when it is not running.
The Injected Voltage Spikes Test is performed by applying specified voltage levels to the vehicle power source. These voltage transients typically occur during engine operation. Throughout the test, the voltage on the power source is increased and decreased to predefined levels. The duration and severity of these transients are adjusted to measure how the electronic equipment responds under controlled spike conditions.
Purpose Objective
- To evaluate the immunity of onboard electronic systems to sudden voltage transients.
- To confirm that electronic equipment operates reliably under defined spike conditions.
- To support more dependable use in military operational environments.
Test Scope Scope
- Application of specified voltage levels to the vehicle power source.
- Ramping voltage transients up to and down from predefined levels.
- Adjusting transient duration and severity to evaluate equipment response.
Technical Implementation Process
- During the test, the power source voltage is increased and decreased to specified levels in a controlled manner.
- Transient duration and severity are configured to capture the electronic equipment response.
- Test results determine whether the equipment can operate within the defined transient envelope.
Application Areas Use
- Improving the reliability of electronic equipment used in military vehicles.
- Verification of equipment designed to withstand sudden voltage transients.
- Compliance evaluation for voltage variations under engine-on and engine-off conditions.
