Application

Three-phase isolating perturbation attenuation transformers with high transient suppression and low noise level. SST & ISO isolates and protect sensitive installations from noisy electrical system grounds, power line spikes and disruptions. Designed and tested according to norm IEC60726. Electrostatic shielding. The output is totally separated from earth and connected to the transformers neutral point. Designed to protect sensitive electronic equipment against noisy electrical systems, transients, voltage spikes and earth faults. E.g.: Automation, process control, industrial electronics, instrumentation etc.
