Resistor REOHM series NTT R D 158

Max. continous power: 60.000 W

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. Through targeted and optimized cooling in a compact space, high power can be achieved with minimal heat generation. They can also be used in environments with high ambient temperatures. The Resistors are available as braking, charging, and high-voltage resistors.

Advantages

  • Very compact construction
  • Suitable for use with high ambient temperatures
  • Specific and optimised cooling for high capacities
  • Very low housing temperature(<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

Typical Applications

Drive systems for motor drives, Mechanical engineering, Elevators / escalators, Pipes, Conveyor technology, Ventilation and air conditioning, Robotics, Automation technology, Power supplies, Wind turbines

  • Temperature switch

Should the resistor be destroyed, it becomes high-impedance. Therefore, each series is available with a temperature switch.
The specified power values were recorded with the Resistors in a horizontal position in the air, at a minimum distance of 100mm from the substrate. The power values apply to standard products with a normal tolerance of +/- 10% at an ambient temperature of 20°C.

All data and configurations can be found in our product datasheet.
