Owing to inductive loads, SMPS Load, Capacitive loads, electronic ballasts and with PWM switching system, the presents AC power lines are superimposed with dangerous spikes, surges, transients, sages RFI noise and harmonics. As a result, failure rates of electronics equipments are on the rise without adequate protection, all electronic equipments are a great risk.
Usually the failure are not seen right way. Repeated stresses from normal electrical transients weaken components and lead to shortening of components life. Lines noises like spikes, surges, transients and so on definitely cause stress on semi conductor components and machine system experience catastrophic failures and software failures, extensive damage to PLC's and storage media, leading to heavy losses of production, data and man hours.
With installing the Welvolt Ultra Isolation Transformer all types of common electrical noises, particularly common mode noise, spikes surges and transients can be eliminated to a greater extent.
