In Case There Is No Output Voltage
The possible cause for no output voltage may be that the overcurrent
or overvoltage protection has operated. The internal protection may
operate if a large amount of surge voltage such as a lightening surge
occurs while turning ON the Power Supply.
In case there is no output voltage, please check the following points
before contacting us:
•
Checking overcurrent protected status:
Check whether the load is in overcurrent status or is short-
circuited. Remove wires to load when checking.
•
Checking overvoltage or internal protection:
Turn the power supply OFF once, and leave it OFF for at least
7 minutes. Then turn it ON again to see if this clears the condition.
Switching the AC Input Voltage between 100 and 200 VAC
The input voltage can be switched between 100 and 200 V by shorting
or opening the input voltage selection terminals. Set the required
voltage as shown below. (The voltage is factory-set to 200 V.)
Note:
A 300-W model is shown above.
Fan Replacement
The service life of the fan is approximately 50,000 hours (at 25
°
C).
The service life varies, however, depending on the ambient
temperature or other surrounding environmental conditions such as
dust. As a preventive maintenance measure, replace the fan within
approx. two years if it is used at an ambient temperature of 40
°
C.
Fans are available as replacements.
Replace the fan as shown in the following illustration.
