REOhm resistors<br />

If installed on a non or poor heat-conducting material, the<br />

performance must be checked due to the reduced heat<br />

dissipation. When mounting vertically, it is essential to ensure<br />

that the connections or terminals are located on the underside<br />

of the resistor. An installation which has the connections on<br />

the uppermost side is not allowed! If several resistors are<br />

mounted one above the other, mutual interference must be<br />

taken into account. Here the compliance with the above<br />

mentioned ambient conditions must be observed and the<br />

installation conditions checked on site. When mounted directly<br />

on a heat sink or cooling surface, Ideal the continuous power of the<br />

resistor can be increased or the surface temperature reduced.<br />

Depending on the type and size of the cooling surface / heat<br />

sink, the output can be increased by a factor of 1.5 - 4.<br />

However, this must be checked Ideal in individual cases, whereby<br />

the specified ambient conditions still apply.<br />
