UL approval for braking resistors
The ULH/ULV series of metal-clad wire-wound high-power resistors is designed specifically for motor braking applications where the user must have UL approval.
The ULH/ULV series of metal-clad wire-wound high-power resistors is designed specifically for motor braking applications where the user must have UL approval The series has a power range from 60 to 1200W with a peak power for a 1s pulse of 25 times the full power rating

High-accuracy networks save on resistors
Dual resistor devices have a combined resistance range from 100R to 330K and are available in both 0805 and 1206 sizes.
The devices come marked with the UL logo and have a high dielectric strength.
These power braking resistors are available with tab terminals and flying lead connections; the flying leads are UL approved to conform to UL safety requirements.
They are built into aluminium housings that are both rugged and strong for protection, and available with noninductive windings, if required.
Customisation of the resistors in the range is possible with thermostatic protection and flying lead length.
Customer part numbers and safety warnings can also be printed on the resistors.
Operating over the temperature range of -55 to +200C, these braking resistors have an insulation resistance in excess of 20Mohm and are tested for short-time overload, moisture resistance, thermal shock, vibration, moisture and load life. Request a free brochure from Rhopoint Components ...
