ASB75 series 

## 75W **Baseplatecooled** 

**AC-DC power supplies** 

The ASB75 series is a range of low profile, half brick, baseplate cooled AC-DC power supplies which require no external components. 

The series includes a built in EMC filter and AC fuse as well as bulk storage capacitor providing a complete AC-DC power solution ready for installation into end applications. 

The ASB75 offers high efficiency to minimise waste heat and heat sinking requirements and operates from -40°C to +85°C on the module baseplate.

## **Application notes** 

## Output voltage adjustment 

The Trim input permits the user to adjust the output voltage up or down by 10%. This is accomplished by connecting an external resistor between the Trim pin and either the +Vo pin or the -Vo pin.

## To Trim Down 

Connecting an external resistor (Rd) between the Trim pin and the +Vo pin decreases the output voltage. The following table can be used to determine the required external resistor value to obtain a percentage output voltage change of Δ%. 

|Trim down (%)|12V|15V|24V|36V|48V|
|---|---|---|---|---|---|
||Rd (kΩ)|||||
|**5**|82|130|180|330|390|
|**10**|9.1|30|20|30|39|



## To Trim Up 

Connecting an external resistor (Ru) between the Trim pin and the -Vo pin increases the output voltage. The following table can be used to determine the required external resistor value to obtain a percentage output voltage change of 5%. 

|Trim up (%)|12V|15V|24V|36V|48V|
|---|---|---|---|---|---|
||Rd (kΩ)|||||
