• Manufacturer Part Number: TSI40-1210
• Description: High Efficiency DC/DC Converter - 40Watt TSI 40 Series
• Manufacturer: TRACOPOWER [TRACO Electronic AG]

Output voltage is adjustable in the range of 5.0~6.0V by connecting a resistor between V.ADJ1pin (11Pin) and V.ADJ2 pin (12Pin).
Resistance value is as the figure mentioned.

+Vs pin and -Vs pin are remote sensing pins.
The connecting point of sensing line and output line will be the output setting voltage. (Between A-B of above figure)
By this function, the voltage drop at the output line can be corrected.
As much as A point and B point gets closer to the load side, Vout (voltage between 7-8pin) will become higher than the output setting voltage.
Note 1. Be sure not to make the Vout（voltage between 7-8pin） over 6.1V.
Note 2. When adjusting output voltage
Note 3. Recommend fixed resistor when mass production.
Note 4. Wire between V.ADJ1-V.ADJ2 pin short as much as possible.
Note 5. Without a resistor between V.ADJ1-V.ADJ2 pin, rating output voltage will be +5.0V.

Note 1. This product can be effected by contacting resistor, so do not use a connector, and solder directly to the print board.
Note 2. For C1, C2 approximate the converter's pin as much as possible, and wire with a bold pattern.
Note 3. Connect +Vs pin and -Vs pin to the capacitor closer to the load side.
This pin is a remote sensing pin so do not keep it open.
Start initial energizing after checking that the adjustable resistor's lug is in the direction of low voltage.
