We have the expertise of designing and manufacturing a wide range of isolation transformers that is available in various specifications. These are meant for reducing the effects of power line problems such as noise, spikes, surges, transients and neutral. Owing to the inductive & capacitive loads, electronic ballasts and with pwm switching systems the present ac power lines are superimposed with dangerous spikes, surges, transients, sags and rfi noise & harmonics. The line noises such as spikes, surges, transients and cause stress on semi conductor components.
the machine systems experience catastrophic program and software failures, extensive damage to plcs and storage media, leading to heavy losses of production, data and man-hours. Isolation transformers are capable of eliminating electrical noises, specially noises, spikes, surges, and transients.
