DCDC电源模块（国外英文资料）.doc

DCDC电源模块（国外英文资料） DC/DC power module features Small size and high reliability; The output is stable and the accuracy is plus or minus 3 [%]. High performance ratio; Multiple input and output voltage; Built-in input filter, low electromagnetic compatibility feature; The aluminum shell is oxidized and the six sides are blocked. Typical application: industrial instrument, digital circuit, electronic communication equipment, satellite navigation, remote sensing telemetry, ground communication research equipment, etc. 1, the input features Input voltage range: 4.75 VDC 5.25 VDC 11.40 VDC 12.60 VDC 14.25 VDC 15.75 VDC 22.80 VDC 25.20 VDC 45.60 VDC 50.40 VDC 2, the output characteristics Output voltage accuracy: nominal output voltage plus or minus 3 [%] Load effect: 20 [%] ~ 100 [%] load change is less than or equal to plus or minus 1.0 [%] (maximum) Source effect: the input voltage is less than or equal to plus or minus 1.0 [%] (maximum) from the low end to the high end. Ripple noise: less than 50mVpk - pk (maximum) Temperature coefficient: [%] 0.02 mm or less / ℃ (maximum) Isolation voltage: input to output (1 minute leakage current 2mA) 1000VDC Storage temperature: - 40 ℃ to + 120 ℃ Relative humidity: 10RH ~ 90RH Working temperature: 25 ℃ to + 85 ℃ Biggest shell temperature: + 90 ℃ Dc-dc power module isolates pressure detection Directly with a pressure gauge to test the DC - DC power supply module, but want to see the first DC - DC module compression performance is how much, if the compression performance is 1000 VDC, cant be used at the time of detection is higher than 1000 VDC to measure DC voltage, if use 1500 VDC to detect possible products directly to burn out, this is destructive testing! Failure analysis: Although the power module is more reliable, it can also fail, in the DC/DC module, there are several possible failures: 1, the module output voltage drop during use; The module stops working; The module output voltage is too high; Module input short circuit; 5,
