When the highest performance in critical applications is considered, IsabellenHutte RUG-Z series of high precision, current-detection resistors offer outstanding temperature characteristics at +85 °C and high 250W permanent power. What RUG-Z range stands out for is 500VAC withstanding voltage, available in 0.1% tolerance, with max current limit of 387A. This makes IsabellenHutte’s high precision resistors ideal use in test & measurement equipment, high current sensing application, laboratory power supply etc. 

The RUG-Z high precision shunt resistor series from Isabellenhütte offers 4-terminal connection technology of very high precision current sensing shunts with a maximum power rating of 250W on a suitable heat sink. Designed for measuring high currents with very high accuracy in power supplies such as those for superconducting magnets. The RUG-Z series from Isabellenhütte has a single pulse power load of 50J (tp <10ms) capabilities.
