External fast blow fuse with a rating of 15A should be used in the application.
If the load is far from the unit, connect S+ and S- to the terminal of the load respectively to
compensate the voltage drop on the transmission line.

Trim Characteristics
Connecting an external resistor between Trim pin and Vo- pin will decrease the output voltage.
While connecting it between Trim and Vo+ will increase the output voltage. The following equations
determine the external resistance to obtain the trimmed output voltage.

Soldering
The product is intended for standard manual or wave soldering.
When wave soldering is used, the temperature on pins is specified to maximum 260°C for
maximum 7s.
When manual soldering is used, the iron temperature should be maintained at 300°C ~ 380°C and
applied to the converter pins for less than 10s. Longer exposure can cause internal damage to the
converter.
Cleaning of solder joint can be performed with cleaning solvent IPA or similative.
Thermal Considerations
Note: When the temperature of this
test point is lower than 116℃, the
module thermal reliability is available

Hazardous Substances Announcement (RoHS Of China)
Hazardous substances

AGQ150-48S05 ○ ○ ○ ○ ○ ○
○: Means the content of the hazardous substances in all the average quality materials of the part is within the limits
specified in SJ/T-11363-2006
√: Means the content of the hazardous substances in at least one of the average quality materials of the part is

Emerson Network Power Co., Ltd. has been committed to the design and manufacturing of environment-friendly
products. It will reduce and eventually eliminate the hazardous substances in the products through unremitting
efforts in research. However, limited by the current technical level, the following parts still contain hazardous
substances due to the lack of reliable substitute or mature solution:
1. Solders (including high-temperature solder in parts) contain plumbum.
2. Glass of electric parts contains plumbum.
3. Copper alloy of pins contains plumbum
