Reliability

Burn-in

The power supply shall go a minimum of 4 Hours burn-in test under full load condition.

Design MTBF

50,000Hrs @25°C, MIL-HDBK-217 Method 2 Components Stress Method

Design Electrolytic Capacitor Life

17520Hrs @50°C Full load and units continuously working.

Note

Measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1 uF & 10uF parallel capacitor.

Test spare parts: test voltage for 500 VDC, 65% RH @ 25 °C.

The SPS is considered a component which will be installed into final equipment. The equipment must be re-confirmed that it still meets EMC directives.
