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?
