Isolation Transformers
Osborne’s Isolation Transformers are used to step-up, step-down and isolate voltages in single phase circuits. Isolation may be used to provide output circuit immunity from voltage spikes and noise (both common-mode and transverse-mode) present on the input system. The isolation can allow separate grounds on both the input and output sides of the transformer. Osborne also designs with a range of electrostatic shielding to provide several levels of noise immunity.
