Constant Voltage Transformer

The Constant Voltage Transformers is designed to protect your Computer, EPABX, FAX and every other kind of sophisticated equipment from electrical hazards.


The Constant Voltage Transformers provides clean, isolated power free from spikes, surges and line disturbances; so necessary for microprocessor based systems. Instant correction of voltage is provided and any rapid change in input line voltage is taken care of. It obviates the need for an additional isolation transformer.


The machine provides overload, overvoltage and short circuit protection. High isolation between output and input helps in suppressing spikes and transients and ensures zero potential between ground and neutral of output. Minimum harmonic distortion is obtained at the output even if square or distorted wave form is fed at the input.
