The special version of the V204-F was developed for special applications requiring extremely limited electromagnetic compatibility interference (EMI). At full power at the output (22A and 120V) only 50mVpp could be measured. |
|
This interference suppression was achieved by using an extra filter in addition to the LC output filter (which was already integrated). We also made use of filtered power supplies. All signal inputs and outputs are also fitted with lead-through filters developed specially for this purpose. |
|
This device demonstrates that, with the corresponding experience, highly efficient PWM switching controllers can also be built completely free of interference.
