*Avoid short circuit between +BC/R and -BC.  It may cause the failure of inside components. 

- *Keep TRM open, if output voltage adjustment is not necessary. 

- *If remote sensing is not necessary, connect between +Vout & +S and between -Vout & -S.

## **TUNS-series** 

## **Implementation・Mounting Method** 

## Mounting method 

- ¡ Use with the conduction cooling (e.g. heat dissipation from the aluminum base plate to the attached heat sink). 

- ¡ Use a heat sink that larger than the power supply and has a large thickness so that the alminum base plate can be cooled uniformly. 

- ¡ The unit can be mounted in any direction. When two or more power supplies are used side by side, position them with proper intervals to allow enough air ventilation. Aluminum base plate temperature of each power supply should not exceed the temperature range shown in “derating”. 

- ¡ Avoid placing the AC input line pattern layout underneath the unit. It will increase the line conducted noise. Make sure to leave an ample distance between the line pattern layout and the unit. Also avoid placing the DC output line pattern underneath the unit because it may increase the output noise. Lay out the pattern away from the unit. 

- ¡ Avoid placing the signal line pattern layout underneath the unit because the power supply might become unstable. Lay out the pattern away from the unit. 

- ¡ High-frequency noise radiates directly from the unit to the atmosphere. Therefore, design the shield pattern on the printed circuit board and connect it to FG or -BC.The shield pattern prevents noise radiation. 

- ¡ When a heat sink cannot be fixed on the base plate side, order the power module with “-T”option. A heat sink can be mounted by affixing a M3 tap on the heat sink. Please make sure a mounting hole will be connected to a grounding capacitor CY.

|Standard|M3 tapped|
|Optional : -T|f3.4 thru|



## Stress onto the pins 

- ¡ When too much stress is applied to the pins may damage internal connections. Avoid applying stress in excess of that shown in right figure. 

- ¡ The pins are soldered onto the internal PCB. 

- Therefore, Do not bend or pull the leads with excessive force. 

- ¡ Mounting hole diameter of PCB should be 3.5mm to reduce the stress to the pins. 

- ¡ Fix the unit on PCB (fixing fittings) by screws to reduce the stress to the pins. Be sure to mount the unit first, then solder the unit. 

## Soldering temperature 

- ¡ Flow soldering : 260 C for up to 15 seconds. 

- ¡ Soldering iron (26W) : 450 C for up to 5 seconds.

## **Derating** 

## Output voltage derating curve 

- ¡ Use the power modules with conduction cooling (e.g. heat dissipation from the aluminum base plate to the attached heat sink). 

- Below shows the derating curves with respect to the aluminum base plate temperature. Note that operation within the hatched areas will cause a significant level of ripple and ripple noise. 

- ¡ Please measure the temperature on the aluminum base plate edge side when you cannot measure the temperature of the center part of the aluminum base plate.In this case, please take 5deg temperature margin from the derating characteristics shown in below. Please reduce the temperature fluctuation range as much as possible when the up and down of the temperature are frequently generated. Contact us for more information on cooling methods.
