DUT Enclosure - SimpleHB 3400 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 HB3400 is a basic tabletop test hood, featuring a wide opening range that makes it ideal for bulky DUTs. It can be externally connected to a variety of our test devices.
