The HPRS Series from IET Labs combines precise resistance setting with power handling capabilities up to 250 W. It is an ideal solution for power supply testing, power electronics development, load simulation, and demanding laboratory applications where conventional resistance decades reach their limits.

HPRS by IET Labs: High-Power Resistance Decade for Precision Testing and Load Simulation

Accurate resistance setting is a fundamental requirement in many laboratory and development environments. However, when higher currents and power levels are involved, conventional resistance decades often become a limiting factor.

The HPRS (High Power Resistance Decade) Series from IET Labs was developed specifically to address these demanding applications.The HPRS combines precisely defined resistance values, excellent stability, and power handling capabilities of up to 250 W. This makes it suitable not only as a precision resistance substituter, but also as a flexible tool for load simulation during power device testing.Its design incorporates high-quality power resistors with low temperature coefficients, ensuring stable performance even under elevated loads.

Resistance values can be quickly adjusted using decade switches, eliminating the need to replace resistors or reconfigure the test setup.Typical applications include testing and development of power supplies, DC/DC converters, battery systems, power electronics, and measurement equipment.

Precisely defined resistance values help create repeatable test conditions and simplify performance verification of the device under test.By combining accuracy, stability, and high power capability, the HPRS Series provides an efficient solution for laboratories and test facilities that require more than a standard resistance decade.
