Therefore, please use from taking enough tests.

■Usage Cautions● Always mount fuse on the plus side of input for ensuring safety because the fuse is not built-in the product.
Please select the fuse considering conditions such as steady current, inrush current, and ambient temperature.
When using a fuse having large rated current or high capacity input electrolytic condenser, by combining
another converter and input line and input electrolytic condenser, fuse may not blow off in the case of abnormality.
Do not combine high voltage line and fuse.
● The output voltage accuracy may be affected by the COM sink current.
If you want to maintain the accuracy of the output voltage, adjust the current value between VO+～COM and COM～Voby adding a resistor or the like so that the current value is the same between VO+～COM and COM～VO-.
