This resistor is designed for applications requiring high-power pulse energy absorption, such as in circuits that need to handle large transient energy spikes. It is particularly suitable for use in environments where forced air cooling is not available or where natural convection cooling is preferred. The product is ideal for scenarios such as:
- Motor Braking : Used in variable frequency drives (VFDs) and electric motors for regenerative braking.
- Pre-Charging Circuits : Employed in power supplies to absorb surge currents during pre-charging processes.
- Energy Dissipation : Utilized in systems that require rapid dissipation of stored energy, such as inductive loads.
