Higher power ratings on request

  

Note

The ratings apply for 100 % duty cycle and free access and exit of cooling air.

In general: Is the ambient temperature higher than 40 °C, the continuous power must be reduced by 5 % per 10 K temperature rise.

REOhm series 156 (UL)

Max. continous power: 1.500 W

Design with different protection ratings

                                  IP20 / IP40                                                         IP20 / IP40 with temperature switch

 

                                 

                                 IP54 / IP65                                                  IP54 / IP65 or higher with temperature switch

 

Protection ratings

Depending on the design and execution various types of protection ratings can be realized up to IP66. At protection ratings less than / equal IP40 the temperature increase must be at the surface resistance max. 300K. For a higher degree of protection (> IP40) a maximum temperature increase of 200K is allowed.

Attention! Duration overtemperature values of> 200 K could result to an impairment of protection rating.

 

Overvoltage protection

It is possible to control the temperature of the resistance by using a temperature switch. In case of exceeding a rated temperature the temperature switch opens and can, for example, trigger an existing signaling contact. The temperature switch is mounted externally in protection class IP20 / IP40 and provided with two connection strands.

At IP54 / IP65 or higher, the temperature switch is integrated in the resistance and provided the connection with a temperature resistant cable.
