REOhm series 153 (UL)

Max. continous power: 360 W

REOhm series 153 (UL)

Unique Selling Point


  • Small dimensions, 
  • Fast connection
  • Short-circuit proof
  • Matching to any frequency converter
  • Can be used under rough conditions 
  • Vertical or horizontal installation possible
  • High-resistance at overload
  • Protection class up to IP65
  • Certified for railway engineering

Description


The BW 153 braking is designed  for drives with frequency converters of small to medium output. The installation is close to the frequency converter. 
In addition to the high protection class IP66, the profile resistors REOhm 153 are also UL-certified and have a power of 100 W up to 400 W (also as combination).

 Maximum energy with minimum space

  • Unity-version can be assembled as low-profile and upright
  • Suitable for IP 65 applications
  • The REO flat resistor can be screwed under or on
    the side of a frequency drive using a mounting plate
  • In case of failure of resistor, this will become highly resistive
  • Test voltage: 2,5 kV AC (at 900 V rated voltage)

Optional

  • With temperature switch
  • Cover for protection against high surface temperatures


Technical Data


  • Resistance values : 0,26 - 2000 Ohm
  • Continuous power : 100 - 400 W
  • max. operating voltage : 900 V

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.
