Application note: TPP150-output-voltage-adjustment,

page 1 of 1, rev.: 14. April 2016

As per datasheet, the output voltage level of the TPP 150 power supplies is adjustable ±10%.

Step 1:

Disassemble the fan by removing the screws in the num-

bered order

Step 2:

Now, the adjustment potentiometer can be seen th-

rough the vent holes. We suggest to adjust the output

at power on condition under no load. Turning ccw

decreases the output voltage, turning cw increases

the voltage. Please make sure to use an isolated screw

driver for safety reasons.

Note; The output power of the power supply must not

be exceeded. If the output voltage is increased > Vout

nom, the load level must be lowered in order to ensure

Pout = 150W max.

Step 3:

Re-assemble the fan by tightening the screws in the same order as removed. Tightening torque = 0.5 – 0.6Nm. We

recommend to use bolt adhesive to lock the screws and prevent them from being loosened by the vibration of the

operating fan.

TPP 150 Series Output Voltage Adjustment As per datasheet, the output voltage level of the TPP 150 power supplies is adjustable ±10%. Step 1: Disassemble the fan by removing the screws in the numbered order Step 2: Now, the adjustment potentiometer can be seen through the vent holes. We suggest to adjust the output at power on condition under no load. Turning ccw decreases the output voltage, turning cw increases the voltage.
