DUT Enclosure - Basic HB 2100, HB 5000 Test cages are ideally suited for test station setups requiring effective contact protection. The DUT cannot be touched while hazardous voltages are applied, thanks to the test hood. Opening the hood triggers a forced shutdown, immediately stopping the generation of hazardous voltages or currents. The HB5000 is a bigger version of the HB2100 that accommodates a 19" test device up to 5U in height, providing an ideal all-in-one desktop solution for safety testing. Subject to change and error. Please note: that in Europe, we use a comma as the separator, while in the USA, a period is used.
