RB-SERIES RESISTORS

Compact, Pulse-Resilient Performance for Heavy-Duty Industrial Applications

Optimised for both continuous loads and repetitive pulse duty, RB-Series resistors utilise a ceramic or steatite core with precision copper-nickel or nickel-chrome winding, providing excellent thermal conductivity and electrical stability. When correctly mounted to a heatsink, power ratings range from 12 W to 250 W, with operating voltages up to 2,300 VAC depending on the model.

RB-SERIES RESISTORS

Built for High-Pulse Applications

The RB-Series is specifically engineered to withstand repeated pulse loads and short-term overload conditions. Properly heatsinked units can safely absorb significant surge energy and sustain up to five times their nominal power for short durations, making them an ideal choice for heavy-duty control systems and power management applications.
