FAQ&Important Notices

＜FAQ＞

Q.	If I input power to the VIN terminal, will the specified power be output?
A.	Our power supply module requires peripheral parts (temperature fuse, input noise filter, input rectifier diode, output smoothing capacitor). If you add an external component, the specified power will be output. For details, refer to the external component selection method and explanation in the "Application Note" of each product. For some products, it is also described in "Application circuit example" in the data sheet.
Q.	What is the composition of the external parts?
A.	Our power supply module requires peripheral parts (temperature fuse, input noise filter, input rectifier diode, output smoothing capacitor). For details, refer to the external component selection method and explanation in the "Application Note" of each product. For some products, it is also described in "Application circuit example" in the data sheet.
Q.	Is there a difference in usage with and without FG (frame ground)?
A.	Peripheral parts configuration is different.For details, refer to the external component selection method and explanation in the "Application Note" of each product.
Q.	Have you obtained UL certification?
A.	UL62368-1, CSA C22.2, UL60950-1, CSA C22.2 No.60950-1 certified. Please check "UL certification status by product" on the menu page for details.
Q.	Is it compatible with ROHS and SVHC?
A.	We are able to respond. For details, refer to "Environment&Rohs" on the menu page.
Q.	Is it possible to input AC?
A.	It can be handled via external parts.Please check "UL certification status by product" on the menu page for details.

＜Usage cautions＞

Always mount fuse on the Live 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 at your own responsibility.
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.
