Servo Voltage Stabilizers
Total control of power quality and voltage fluctuations
Voltage variations are an increasingly common and dangerous nuisance that can damage electronic components like power supplies,
drives, PLCs, controllers etc. Their effects are widely felt in CNC, Printing, Textile machines in addition to Laboratory, Data processing, Medical &
Telecommunication equipments. As an effective solution, UCPL has designed state of the art Voltage Stabilizers to protect these equipments against
voltage variations and offering improved power quality, thereby minimizing break downs of costly equipments.
Our Stabilizers are manufactured out of prime grade of magnetics & electrical conductors, housed in enclosures manufactured on CNC machines & powder
coated as per IS/BS standards. Stringent quality assurance programme at various stages of manufacturing ie. raw materials, sub assemblies,
assembly & finished goods ensures high reliability & consistent performance.
Our Servo voltage stabilizers provide controlled & desired output voltage against wide range of voltage fluctuations. Apart from protecting the equipments
from damage, they save energy during high voltage conditions.
Unique Features
Instant Response & Fast Corrections:
Variable speed servo motor and proportional control circuit provide a response time of 10msec. to correct voltage fluctuations without noise or oscillations in output.
Lower Running Cost:
Due to high operating efficiency of better than 98% as compared to 95% from other brands. Fig. B indicates savings at different KVA ratings, with our equipments.
Digital Metering System:
Data logger with LCD/LED display screen provides detailed information about various electrical parameters to help monitor power quality (optional).
Universal Fit:
Designed to work on unbalanced line and load conditions when each phase is individually controlled with separate variable speed motors and electronic controls.
D.G. Compatibility:
Special RMS sensing circuit eliminates drift in output voltage, current, frequency even with distorted waveform to avoid unnecessary tripping.
Quality Components:
Components conforming to CE/IS/BS/VDU standards are used and thoroughly tested as per relevant standards.
Fast Payback:
Reduced power loss and resultant lower running cost yield higher cost savings and help the customer recover the cost difference in few months.
