LDC302 Abnormal Voltage Transitions Test
MIL-STD-704
MIL-STD-704 Aircraft Electrical Power Specifications Standard, prepared by the United States (US) Department of Defense, is a military standard that covers issues such as voltage, frequency, phase, fluctuation and maximum current in a military aircraft and its equipment. The most current version of the standard is MIL-STD-704F_CHG-1, published in 2016. However, this standard is not a standard that only covers the US military and its subcontractors, but is a globally accepted standard for evaluating the suitability of military aircraft and systems. It is converted to the voltage levels required for the operation of the equipment used in the aircraft power system, which comes with a power source that complies with the MIL-STD-704 standard. In order for a piece of equipment to operate in accordance with the MIL-STD-704 standard, it must pass MIL-STD-704 tests to see its effects under difficult conditions and to verify its conformity.
The LDC302 Abnormal Voltage Transitions Test is used to verify that 28V DC power handling equipment operates at specified performance when subjected to abnormal voltage transients as specified in MIL-STD-704.
In the LDC302 Abnormal Voltage Transitions Test, the usage equipment has passed if it operates and maintains performance as specified in the usage equipment performance specification document for abnormal aircraft electrical conditions when subjected to transient voltage fluctuations within the abnormal limits of the applicable version of MIL-STD-704, as specified in the table. acceptable.
Unless otherwise specified in the LDC302 Abnormal Voltage Transitions Test operating equipment performance specification document, operating equipment should automatically return to specified performance for normal aircraft electrical conditions when power returns to normal limits.
The equipment used in the LDC302 Abnormal Voltage Transitions Test must not be damaged or cause an unsafe situation.
