HPRS Series high power resistance decade box
The IET Labs high-power decade resistance substituter (HPRS) series is a family of resistance decade boxes offering a broad choice of high-power, excellent-performance resistance sources.
The IET Labs HPRS Series resistance decade boxes employ state-of-the-art precision resistors of various types for high accuracy, high stability, and low temperature and power coefficients of- resistance. High-power resistors within the unit are made available without sacrificing other electrical properties.
The standard models offer a choice of 3 to 8 decades. The panels are clearly labeled showing the step size and maximum voltage and current limitations for each decade.
Features
- Resistance from 1mΩ to 10MΩ
- Power rating: 225W / decade, 250W max. or higher (contact IET for custom higher power units)
- Accuracy: 0.5% or 1%
- Special and custom configurations available
