REOHM Resistor Series BW 151

Braking resistor, max. continuous power: 300 W

Description

Braking resistor for drives with small to medium power frequency converters or usable as a charging resistor.
Mounting close to the frequency converter.

  • IP54 protection class
  • Higher protection classes on request
  • Test voltage 2.5 kV AC
  • Other power ratings and mounting dimensions on request

Advantages

  • Easily combinable
  • Inherently safe
  • Very flat and compact design with open grooves for vertical mounting
  • Adaptable to any frequency converter
  • Very good heat dissipation, mounting on heat sink possible
  • High-impedance in case of overload
  • Quick connection
  • Also with UL certification
  • Optional with temperature switch

Typical Applications

Braking resistor for drives with small to medium power frequency converters or usable as a charging resistor. Installation close to the frequency converter.

In case of destruction, the resistor becomes high-impedance, therefore each series is available with a temperature switch. The specified power ratings were recorded with the resistors in a horizontal position in the air, with a minimum distance of 100mm to the substrate. The power ratings refer to the standard products with a normal tolerance of +/- 10% at an ambient temperature of 20°C.
