We Are Manufacturer & Supplier of Constant Voltage Transformer.

Features :

• In Hi-Rel  CVT, the AC mains powers the input winding which is widely separated physically from the isolated output winding. The input winding normally runs at very moderate Flux linkage levels. The output winding exhibits an intrinsic energy characteristic and this energy storage operates in conjunction with mains capacitor to produce self-generated AC flux field which is indirectly excited from the input winding.
• The result is instantaneous voltage regulation. No transient and spikes. Sinewave output. A perfect answer and remedy for every electronic equipment.

 
Salient Features :  

• No semiconductors or moving parts used, hence very high reliability
• No feedback control used
• Intrinsic current limiting and short circuit protection
• Output voltage correction within ½ Cycle ( 10 ms) from no load to full load for specified load and line variation
• Short term over load capability
• Energy storage for line loss up to 3 ms at typical loads
• Higher input voltage control range, for loads less than rated load
• Very high line transient/spike rejection capability and excellent input to output isolation characteristics
• Output floating (optional)     

Range : Hi-Rel CVT is available in a wide range. from 100VA to 5000 VA with load test conducted at unity power factor for all ratings.

Fields of Application : Computers, Data Processing equipment, Colour Photography Labs., Bio-medical equipment, PA equipment, Telecommunication, TV, VCD/DVD recorders & players, Teleprinters, Fax machines and all other sensitive electronic devices.

Recommendations :

• Keep magnetic storage and display devices like Diskettes, Spools, Monitors etc. away from the CVT.
• Switch on the CVT before switching ON the attached peripherals and while switching off, switch OFF attached peripherals first and then the CVT.
• Avoid using the CVT for high inductive loads.
• Check frequency before using the CVT with a generator. Recommended frequency: 50± 1Hz
• Switch OFF the CVT when not in use.   

Hi-Rel is a Brand engaged in manufacturing & supplying high quality Isolation Transformers that are exported to our global clients.Isolation Transformer offers complete line Isolation, with enhanced common mode of surge suppression and continuous filtering to eliminate harmonic distortion.Isolation Transformer manufactured by us eliminates all type of electrical noises(Common Mode Noise) as well as ground potential.Isolation Transformer isolates sensitives equipments from noisy power lines.It Provides electrostatic shielding.

Description :

• Technically any transformer has primary and secondary separated from each other but they are different w.r.t contruction, specification and performance.In Shielded Transformer, for low impedance paths exists for  noise to pass to secondary and vice-versa.
• Isolation Transformer are specially designed for sensitive equipments such as CNC Machines, Telecom Equipments, computers etc. & helps in Isolating such equipment getting disturbed from noise present on power lines created by other electrical machines connected to the system.
• Multiple Shielding Techniques employed increases DC Isolation to over 1000 MOhm and reduces inter-winding capacitance to very low level thus helps in isolating sensitive machines from power line noises.

HighLights

• Isolates the equipment from noisy power line.
• Reduces power line noise, surges, spikes & transients.
• High Insulation resistance.
• Provides the complete electromagnetic & electro-static shielding.

K-Rated Isolation Transformer : K-Rated Isolation Transformers eliminates all type of electrical noise including common mode noises.These K-Rated Transformers are available in different levels of noise attenuation capabilities.

Ultra Isolation Transformer : Our wide range of ultra Isolation Transformer offer wide range  that  have excellent protecting techniques.Our transformer are technically sound in every dimensions.

Features :

• Designed with split winding constructions and bifilar connections to reduce overall capacitance of the winding.
• The use of high Insulating material and special shielding techniques results in attenuating common mode and minimizing transverse mode noise.
• The Core and its magnetic Properties are properly selected to exhibit sufficient leakage inductance to provide greatest possible attenuation of normal mode power line noise, consistent with the transfer of fundamental power frequency.But all higher frequencies are blocked.
• The Use of Faraday’s Unique Box shielding and special techniques totally block the transfer of electric noise even by static charge, by way of proximity or R.F. Noise.
• Due to the better regulation, it  does not generate common mode impedance coupling effect.

Application Area :

• If ground potential of systems units are different from each other and are exposed to the effects of instability at high frequencies.
• If ground of the equipment cannot be earthed.
• Where no slighted current leakage is permitted.

Benefits :

• Protect against strong lightening, impulse noise, bus short-Circuit, accidental discharge of capacitors etc.
• Protect the Micro Processor based machines and equipments from damage due to electric noise, spikes etc.

Ultra Isolation Transformer : Our wide range of ultra Isolation Transformer offer wide range  that  have excellent protecting techniques.Our transformer are technically sound in every dimensions.

Features :

• Split winding constructions and bi-filar connections is made in such way that it reduce overall capacitance of the winding.

• High Insulating material and special shielding techniques are reason for its common mode and minimizing transverse mode noise.

• The core and its magnetic properties are chosen in such a way which display enough leakage inductance which offer normal mode power line noise, which is in sync with the transfer of fundamental power frequency.And all the higher requencies all blocked.

• Transfer of electric noise is blocked by Faraday’s Unique Box shielding and apt techniques.
