10. Before concluding that the unit is at fault
Before concluding that the unit is at fault, make the following
checks.
(1) Check if the rated input voltage is connected.
(2) Check if the wiring of input and output is correct.
(3) Check if the I/O terminal connection is properly tighten by
regulated torque.
(4) Check if the wire thickness is enough.
(5) Check if the output voltage control (V.adj) is properly ad-
justed. OVP might be trigged and output is shut down.
(6) If use function of the Remote ON/OFF control, check if the
Remote ON/OFF control is properly used.
(7) Check if the built-in FAN is not stopped. Is FAN stopped by
something irregular or etc?
If FAN stops, the ALM signal turn
“High” level and OTP
might be activated.
(8) Power supply has ventilating holes on the front and back
panels. Check if there is any irregulars or dust, etc.
(9) Is the chassis of power supply hot abnormally? The output
is shut down by OTP operation. Please re-input after the
unit is cooled down suffi ciently.
(10) Check if the output current and output power does not over
specifi cation.
(11) Audible noise can be heard when input voltage waveform
is not sinusoidal.
(12) Audible noise can be heard during dynamic load operation.
