9 Before Concluding Power Module Damage
Verify following items before concluding power supply damage.
(1) No output voltage
・ Is specified input voltage applied?
・
Are the remote ON/OFF control terminal (RC), output voltage trimming terminal (TRM) correctly
connected?
・ For case where output voltage adjustment is used, is resistor or variable resister setting,
connections correctly done?
・
Are there no abnormalities in the output load used?
・
Is the case temperature within the specified temperature range?
・ Is the ambient temperature within the specified temperature range?
(2) Output voltage is high
・
For case where output voltage adjustment is used, is resistor or variable resister setting,
connections correctly done?
・
Is the ambient temperature within the specified temperature range?
(3) Output voltage is low
・ Is specified input voltage applied?
・
For cases where output voltage adjustment is used, is resistor or variable resistor setting,
connections correctly done?
・ Are there no abnormalities in the output load used?
(4) Load regulation or line regulation is large
・
Is specified input voltage applied?
・
Are the input terminals and the output terminals firmly connected?
・ Is the input or output wire too thin?
・ Is the input or output wire too long?
(5) Output ripple voltage is large
・
Is the measurement done according to methods described in the Instruction Manual or is it an
equivalent method?
・ Is the input ripple voltage value within the specified value?
