MIL-STD-810 Temperature Testing for Custom Power Supplies<\/h1>\n<\/div>Viable Power performs MIL-STD-810 temperature testing on its power supplies in accordance with the specific client requirements and needs. These tests are performed at our facilities to ensure the durability and reliability of our power supplies when operating in extremely hot, cold, or rapidly fluctuating temperatures.<\/p>\n
When temperature testing under MIL-STD-810 (current version being MIL-STD-8910H), we perform a series of stress tests that help ensure the longevity, reliability, and durability of our ruggedized power supplies.<\/p>\n
We look for specific things, such as the ability of the circuit boards, transistors, and other parts of the power supply to stand up to high heat and freezing temperatures while continuing to function normally.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
MIL-STD-810 Temperature Testing That We Perform<\/h2>\n
We perform three separate temperature tests:<\/p>\n<\/div>

Test Method (502.7) \u2013 Low Temperature<\/strong><\/p>\n<\/div><\/li>- <\/i><\/span>\n
Test Method (503.7) \u2013 Temperature Shock<\/strong><\/p>\n<\/div><\/li><\/ul>Each test has up to three procedures that we perform in all temperature ranges included in the specification (with or without humidity). The temperature\/humidity tests can be done at operating or non-operating conditions.<\/p>\n
To perform the tests, we utilize a state-of-the-art thermal chamber that has the following features:<\/p>\n<\/div>
- <\/i><\/span>\n
Temperature range of 65\u00b0C to +190\u00b0C (-94\u00b0F to +375\u00b0F)<\/p>\n<\/div><\/li>
