Control Transformers Dealers

The output ratings for continuous duty are for the maximum output voltage. For lower voltage taps the permissible output with constant current must be correspondingly reduced. The output supply for an ambient temperature of maximum 45°C & altitudes upto 1000 meters above sea level. In case of continuous duty with short time loads, Control Circuit Transformers can be subjected to upto 300 contactor operations per hour with the short time loads in excess of the continuous ratings. The restaurant drop of the on - load output voltage will not exceed 5%.

Control Transformer are two winding transformers used for safely isolating measurement and loads from Input line. Industrial control transformer provides step down voltages, enabling control circuits to be isolated by ensuring reliable operational voltage for control and auxiliary circuits.     Control transformers are available in a variety of primary and secondary voltage combinations     from 120/240/380/400/415/440 V primary, 24/110/220 V secondary upto 10 KVA     Conductor: Electrolytic grade Copper Strips/Wires or Aluminum     Core: CRGO or CRNGO type EI or strip     Insulation Class: Class H or Class F        Input and out are terminated using bus bars or connectors on board​

We also offer a wide range of control transformer, designed to balance electric supply in medium voltage switchgear. We use quality grain-oriented core steel and copper conductor to manufacture this control transformer to offer strength and high performance. Our range of control transformer is available in both single and three phase configurations with some models capable of vertical mounting to conserve space.

FEATURES   Capacity upto 50 VA to 100 KVA In tape wound,resin cast & oil cooled With & without ensclosures

The Basic function of a transformer is to increase or decrease the alternating voltages in electric power applications. GPD transformers go beyond the basic functions to efficiently convert voltage, provide isolation, generate impedance in the circuit and provide safe power for industrial and medical applications. Our transformers are mainly customized products developed with customer application in mind. Being a customer focused approach, we have developed a wide customer base in various fields like Motor Drives and Controls, Plastic Processing Machinery, Textile processing Machinery, Mining Equipment, Wind turbine and Solar Inverters, Marine applications, Medical Applications, etc. Under our UL approved file no. E301764 and E302166, we manufacture control transformers of up to 40KVA. GPD also manufactures CE approved control and power transformers as per the IEC 61558 and IEC 60076 standards. General Specifications Max operating voltage : 1 kV Frequency : 50/60 Hz Protection index : IP 00 Protection class : 1 Insulation class : F Termination : Screw / Studs / Bus bars

We are offering Drive Isolation Transformers for Control Energyfor control energy. Drive isolation transformers are becoming more and more popular manufactured by us since they are easy to control and helps in saving energy. These transformers are used in motor drives such as adjustable speed and variable frequencies. The drive isolation transformers designed here specifically handles the mechanical stresses, harmonics, and voltage distortions. The features included in drive isolation transformer helps in protecting the transformer from the regenerating duty as well as most frequent short circuits. our main task in manufacturing drive isolation transformer is to withstand the stringent mechanical and electrical stresses that are common in the d.c as well as the a.c motor drives. These transformers are placed between the primary and the secondary windings which is known for its electrostatic shields and provides up to 1000 kva bringing to the global market at competitive prices.

These are specifically functional for converting a high voltage of main circuit to a lower voltage. This facilitates the sourcing of power to the control equipment that need more voltage regulation on starting as well as is not fit to be joined with the main circuit. These are idyllic for functioning in conjunction with industrial starter circuits. These are applied in stepping down the high voltage chiefly for the devices & equipment such as Inverters, Medical Equipment, Rectifier transformer, Control Panel, solenoids, DC braking as well as Drive systems and are specifically functional in Hospitals, Commercial places as well as Industries etc. We manufacture our Control Transformer with the best quality components and elements maintaining the standards set by the industry. We also, quality examine their safety and performance to ensure their reliability and faultlessness.

  Through nonstop research and development of the market, we are offering high performing Control Transformer at rock bottom rates. This transformer is precisely designed in complete compliance to the set industry guidelines. Offered transformers are available with us from 10 VA to 3 KVA multi tapping and various voltage and current isolated winding. Our offered transformer is quality examined on a series of quality parameters under the command of our quality inspectors..
