The DB20VA isolation transformer is a 1:1 powerfrequency transformer with a 20 VA rating, designed for 220V input and 220V output. It provides galvanic isolation between input and output and offers antiinterference performance to help protect connected equipment and improve signal integrity. Key benefits Galvanic isolation between source and load to improve safety and protect sensitive devices from mains disturbances. Antiinterference capability to reduce electrical noise and prevent interference from the power line affecting connected equipment. 1:1 voltage ratio maintains the same nominal output voltage as the input, simplifying integration with 220V systems. Simple, maintenance operation as a passive device with no active controls. Compact and robust design suitable for integration in laboratory, workshop, or equipment enclosures. Key attributes Model: DB20VA Type: Isolation transformer Primary voltage: 220V Secondary voltage: 220V Turns ratio: 1:1 Power rating: 20 VA Frequency: Power frequency (50/60 Hz) Features: Isolation, antiinterference Application: Provides isolated 220V supply for compatible devices to improve safety and reduce mainsrelated noise and disturbances Compatibility and use Suitable for equipment that requires an isolated 220V supply to protect against ground loops, noise, and transient disturbances. Works with sensitive measurement or test equipment where clean, isolated power improves performance. Useful in audio/AV setups or small electronic projects where galvanic isolation helps minimize hum and interference. Use cases Laboratory measurements and test benches: isolate oscilloscopes, multimeters, and other sensitive instruments from mains noise to improve accuracy and safety. Audio and AV gear: connect audio interfaces, amplifiers, or video equipment to reduce groundloop hum and electromagnetic interference. Small equipment protection: power control electronics or prototype hardware in educational or development environments that benefit from galvanic isolation and reduced powerline interference.
