REOHM series D 158

Unique Selling Point


  • Very compact construction
  • Suitable for use with high ambient temperatures
  • Specific and optimised cooling for high capacities
  • Very low temperature of enclosure (<50°C)
  • Suitable for standard cooling liquids (water/glycol)
  • High protection rating up to IP66 possible
  • Operating pressure of the cooling circuit up to 4 bar (test pressure 10 bar)
  • Small space requirement

Description


The series D 158 can be used as braking or load resistor for drive technology, industrial applications, test fields, E-Mobility and railway engineering with integrated water cooling. Thanks to localised, optimised cooling, high outputs can be generated in the smallest space with low heat generation. It is also possible to deploy it in areas with high ambient temperatures.

The resistors are available as braking-, load-, or highvolt resistors.

Applications:

  • Drive technology, frequency converters
  • Railway
  • E-Mobility
  • Test systems

 

Maximum energy with minimum space

  • Protection IP20 up to IP66
  • Test voltage 2,5 kV AC
  • Ambient temperature: -15 to +80ºC
  • Other fixing points or power ratings on request

Optional

  • With temperature switch

 

Technical Data


  • Resistance values : 2 - 850 Ohm
  • Continuous power : 1000 - 60000 W
  • max. operating voltage : 1000 V

Higher power ratings on request

 

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

Load diagram 

The power ratings apply for continuous duty. The power ratings can be increased in short-time operation in function of duty cycle by multiplication with the relevant factor from the diagram below or according to the formula as follows.

 

 

 

Resistance value in function of temperature

The resistance values refer to standard products with a standard tolerance of +/- 10 % with an ambient temperature of 20 °C. The resistance value insignificantly changes in function of the winding temperature. Therefore,  resistance changes of approx. +10 % in comparison to the cooled-down conditions may occur.

 

Cooling liquid/Refroidissement 

The aluminium cooling pipes used are suitable for most of the standard cooling liquids and oils. In order to ensure safe operation of the units it is most important to comply with the VBG-cooling water regulations (VBG-R 455 P). Cooling channels: Aluminium (AlMgSi 0,5) Di = 10,5mm; G1/4” inside thread

Cooling medium: for example water with anti-corrosion agent for closed cycle cooling system; oils

The cooling pipes are not suitable for industrial and potable water, aggressive liquids, sea-water or de-ionised water. The maximum inlet temperature is + 25 °C and the maximum drain temperature + 45 °C.

The resistors are designed with a flow rate of 10 l/min. This should preferably not be gone below. A lower flow rate may result in reduction of the power. This is to be checked.
