Recommendation for ED value (Duty cycle)
Only for one time shutdown 5%
Multiple stops per hour 10%-20%
Stop and go operation 20%-50%
Long braking operation e.g.(elevator 10th floor) 100%

REO Productfinder


The REOhm braking, damping and charging resistors are characterised by a high degree of functional safety and a long life.
REO braking resistor wires are wound on a frame and enscapsulated. This provides a very high degree of mechanical protection and no susceptibility to vibrations and oscillations.This construction enables the resistor to absorb higher pulse loads and store them temporarily. 
Our resistors are available with protection ratings up to IP65.

Damping- and charging resistors are used to damp over-voltages or to dissipate excess energy which occurs, for example, on braking or starting up. Applications can be found in railway engineering, electric vehicles or commercial vehicles.

Liquid-cooled resistors - compared to air-cooled resistors - can minimize the size up to 80%.


• Compact dimensions

• Low weight

• Very high power density

• Use of power loss for heat management
