Amends
After it delivers it, I will repair three years free of charge for an
emergency breakdown. However, because handling is careless, it becomes for a fee.
Soldering condition
Dip: 240℃-255℃ (within five seconds)
Hand solder: 350℃±10℃ (within three seconds)
Others
This series is designed in our standard power supply for the general electronic
equipment building in. Please do not use it for the equipment (medical equipment,
aircraft, and nuclear power control system, etc.) by which the malfunction and
the breakdown of the power supply threaten the human body and the life directly.
Directions
☆
The short-circuit leaving for a long time doesn't cause the breakdown
and do not do, please.
Please note that there is a case to cause a defective start when a mass
capacitor (about 10,000μF) is connected with the load edge.
The input fuse prevents secondary destruction due to the breakdown of the power
supply, and it doesn't operate normally in the exchange only of the fuse.
Please request the repair to the agency or our company when the input fuse fuses.

Please secure 5㎜ or more from the power supply when you arrange the pattern and

It is likely to make an internal connection disconnected when the stress more
than the necessity is added to the I/O pin of the power supply.
Please adjust the stress to 2㎏f or
less by horizontal direction by 1㎏f
