Optimum performance of sophisticated electronic equipment is highly dependent on the stability of the mains voltage. The continuously fluctuating mains supply,
transients, spikes & surges produce harmful effects.
‘bluebird’ constant voltage transformer gives an effective solutions to all these problems.
Constant voltage transformers are based on Ferro-Resonance Principle & it consists of two basic components i.e. Ferro-Resonant transformer and capacitor.
‘bluebird’ constant voltage transformers are ideally suitable for computers & like systems. Data processing equipment, Bio – Medical equipment, Telecommuniation equipment. Telex, EPABX, Electronic Typewriter, Fax Machines and any other sophisticated electronic equipment which requires a precise mains supply.
KEY FEATURES
Salient Features :
High reliability as no semi conductors/moving parts used.
Provide relatively sine wave output irrespective of quality of input wave shape.
Instantaneous voltage regulation.
Output highly isolated from mains for suppression of transients & spikes.
Short-term over lOAD capacity.
Intrinsic current limiting & short circuit protection.
Higher input voltage control range for lOADS less than rated load.
