The LocBuffer in a 25V variant.

If your track voltage is higher than 16V dc, it is advisable to use the 25V variant so that more capacity is possible.

Tip for measuring your web tension:
You can ONLY measure a DCC track tension with adapted measuring equipment or an oscilloscope. But what many do not know is that the decoder has the electronics to function. You can therefore measure the track voltage on the V + and GND connections of the decoder. In the manual of the decoder you can read where you can find the V + and GND.

The LocBuffer 25V kit consists of the following smd components as standard:

3 Tantalum capacitors 100uF 25V
1 Charging resistor 100 Ohm 0.25W
1 Discharge diode 1N4007
