Riedon has expanded its line of high-performance power resistors to include power ratings up to 1,000 watts and a maximum voltage rating of 5,000 volts. The rugged PFU series offers a compact package intended for heatsink mounting or, for the best thermal control, a liquid cooled chiller. The PFU800 and PFU1000 are available in E24 resistance values (plus 2 Ω and 5 Ω) ranging from 0.5 Ω to 1 MΩ with tolerances as tight as 5%.
