AGT Constant Voltage Transformers - AEL Group

1 AGT Constant Voltage TransformersAGT Constant Voltage Transformers (CVTs) areideal maintenance free solutions for loads that cansuffer erratic operation or be damaged by electricalnoise (common or series mode), local transients,mains power sags, surges and Voltage Transformer (CVT)Galvanic IsolationHigh common and normal mode noiseattenuationSag, surge and brownout protectionSine wave output (regardless of inputwaveform)Low installation and running costs(maintenance free)High Mean Time Between Failure (MTBF), over200,000 hours ( years)Easy to installOperationUsing a Constant Voltage Transformer (CVT), aninput Voltage variation of +/-15% is automaticallystabilized to within +/-3% of nominal on the faced with an extreme transient such as alocal lightning strike, the CVT will present a lowimpedance to the mains protecting both itself andany connected loads.

2 The Constant VoltageTransformer generates a perfect sine wave outputeven when fed from square or quasi-square 15000VA for large industrial loadsOptionsAny nominal Input/Output up to 660 VacMains Voltage and frequency to suit geographiclocationPlug and socket or terminal versions availableas standardParallel and Series operation for enhancedreliability and larger power ratings. Contact oursales team for further designs with multiple AC and/or DCoutputsFor sizes above 15 KVA 1000VA - all standard units come with a baseplate for ease of fixingOutstanding Spike and Electrical NoiseProtectionProviding unparalleled reliability and conditioningperformance, spikes and electrical noise areneutralised with attenuation as high as 75dB.

3 Inaddition the input and output transformer windingsare physically separated (Galvanic Isolation), thisseparation ensures that there is no connectionbetween the mains supply and the load. A CVTtherefore provides an impenetrable barrier tospikes and high frequency electrical noise. Thisbarrier also works in reverse to prevent a noisy load from polluting the mains Mode NoiseCommon mode NoiseSuperior Sag, Surge and BrownoutProtectionMains Voltage Sags and Surges of as much as50% are automatically corrected by a CVT.

4 A CVTwill ride through most brownouts or mains dipsbecause of its resonant long as at least 30% of the normal supplyvoltage is present a suitably selected CVT canprovide adequate power for your critical Electronics Limited.

A CVT is themost efficient way to drive a switched mode powersupply (SMPS). Input surges are reducedprolonging life and conduction times arelengthened. In addition the CVT providesharmonic buffering and improved reservoircapacitor hold up for the inevitable supply micro-breaks, which occur with grid protection Electronics Limited.
