This wide range makes it possible to choose the right rheostat according to the desired resistance and intensity.
If you are finding it hard to choose between 2 models, it is always better to opt for the rheostat that accepts the highest intensity, the 320W model.
Technical characteristics:

• Coiled wire embedded in a ceramic tube
  
• Safety sockets (with coding pin for grounding)
  
• Umax: 50 V
  To avoid damaging the devices, it is advisable not to exceed 75% of the maximum capacity of the rheostats for more than 15 minutes.
