Control Transformer Manufacturer in Pune


Your search for reliable and efficient transformers ends at ProstarM Transformers. 25 years of quality work in this field has established us as a reliable Control transformer manufacturer, supplier and exporter. Control transformers are ideal for electrical or electronic circuits. They are used in an electronic circuit that needs constant voltage or constant current with a low power or volt-amp rating. Our control power transformers provide power control in various Voltages i.e. 24 OR 110 OR 200 to 250 Volts from 380V to 480V and thus provide more than one secondary output. The outputs are used to operate Contactors, SMPS, Break Coils, Panel lighting etc.

Universally, these types of transformers are used in Control Panels, Machine Tools, Instruments, Lift and Crane Control units etc.,

where continuous duty applications are used for seamless performance of entire systems. Our sturdy design, highest stability and durability offer better control without any voltage Spikes and dips. Thus it protects the control systems, aiding them to work flawlessly. The non-stop production and profits is thus ensured.

Our control transformers have wide applications and they are being used all over the world with different machines, controllers, instruments, etc


Our three phase transformers are used to supply isolated power to machines including CNC Machines; where step-down voltages are required. They ensure clean output; with minimum spikes and surges. Robotic Controllers also need three phase supplies of 50 OR 60 Hz.

We manufacture and supply these types of Transformers with or without enclosures. Various taps like Pri 380–400—415–440 V, Delta & Sec 200—220 V, Star; are generally taken out from primary and secondary to provide exact voltage requirement at sites. Necessary ducts/wedges are provided for cooling of windings between windings and core & between windings also.

These transformers generally have 1:1 OR 1:0.5 ratio and are Delta/Star configured to avoid input spikes and surges entering into output circuits. Additionally we provide electrostatic shield between primary & secondary for better results.

All our products undergo a rigorous quality check as per the Standard Operating Procedures before they leave our factory. Our efficient after sale service assures you a peace of mind.

Our team of technical experts evaluate your requirements of power and machinery and suggest a right solution from our existing range of products or develop a customized solution for you. Our solution is aimed at being cost effective with optimum efficiency for enhanced productivity. The experienced Research and Development team supported by a state-of-the-art facility develop customized solutions for your requirements. The aim is always to delight our customers.


We follow a zero defect policy. To ensure the 100% implementation of the same, we implement stringent Quality Management System. This QMS works at three levels.

1. Pre assembly: All that forms a part of the final product which is delivered to you is checked for quality individually under the prescribed guidelines and parameters; even before it becomes a part of the final product.

2. Assembly: The quality checked parts then come together to take a form of the final product on the assembly line or the manufacturing area. Here, our In-process Quality Control (IPQC) department personnel ensure the monitoring of quality at every step of the manufacturing process.

3. Ready for Delivery: The final product that is ready for delivery then undergoes a final check that involves checking the product on all the prescribed parameters by our well trained and experienced staff. This is a very critical stage in implementing our ‘zero defect policy’ and ensures peace of mind for our clients.
