RESISTOR REOHM BW 151

Braking resistor, max. continuous power: 300 W

DESCRIPTION

Braking resistor for drives with frequency converters of low to medium power or as a charging resistor. Mounting close to the frequency inverter.

  • protection class IP 20 / IP 54
  • higher protection classes on request
  • test voltage 2.5 kV AC
  • other capacities and mounting dimensions on request

ADVANTAGES

  • easily combined
  • intrinsically safe
  • very flat and compact design with open grooves for vertical mounting
  • adaptation to any frequency inverter
  • very good heat dissipation, mounting on heat sink possible
  • high resistance at overload
  • quick connection
  • also with UL certification
  • options available with temperature switches

TECHNICAL DATA

  • Resistance values : 1,1 – 2000 Ohm
  • Continuous power : 50 – 300 W
  • max. operating voltage : 900 V

Typical applications: Braking resistor for drives with frequency converters of low to medium power or as a charging resistor.

Mounting close to the frequency inverter.

Performances: Protection class IP54, test voltage 2,5 kV AC, other capacities and mounting dimensions on request.

DIMENSIONS IN MM

In the event of failure, 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.

We are also happy to produce customer-specific solutions outside our standard portfolio – just contact us!
