Resistor Reohm Bw 155

Max. continuous power: 3.000 W

DESCRIPTION

Braking resistor for drives with frequency converters of medium to high power. Mounting inside and outside the control cabinet is possible.

ADVANTAGES

  • small dimensions
  • quick connection
  • adaptation to any frequency inverter
  • good power to size ratio
  • optional with cover and temperature switch
  • optionally also for aggressive environments (e.g. salt mist)
  • protection type: IP66

TYPICAL APPLICATIONS

Braking resistor for drives with frequency converters of medium to high power. Mounting inside and outside the control cabinet is possible.

SERVICES

  • degree of protection: IP20 / IP65 / IP66
  • test voltage: 2.5 kV AC
  • ambient temperature: 10+40 ºC
  • other services on request
  • other fastenings on request
  • optional with external cooling

In the event of destruction, the resistor becomes high-impedance. Each series is available with a temperature switch.  The specified performance values were measured at a horizontal position of the resistors in the air with a distance of min. 100mm to the substrate. The power values refer to the standard products with a normal tolerance of +/- 10% at an ambient temperature of 20°C.

*With small resistance values, the conductor cross-section is adapted to the current
