Variable Auto Transformer / Variac / Dimmerstat Dealers in Mumbai

• Single phase: Input: 240V, 50/60Hz AC 1 ph. Output: 0-270V, 50/60Hz AC 1 ph.
• Three phase: Input: 415V, 50/60Hz AC 3 ph. Output: 0-470V, 50/60Hz AC 3 ph
• Excellent Regulation: The drop in voltage from “no load to full load” is minimal in Reguvolt Auto-transformers.
• High Efficiency: Careful design and proper selection of copper and core assures the user of low watt loss, as compared to other type of controllers.
• No Wave From Distortion: Reguvolt provides an output voltage wave-form, which is a faithful and distortion less replica of the input voltage wave form.
• Silver Plated Communator: A special silver plating technique is used on the commutator, enabling it to with stand high overloads & maintain constant contact drop. It is also ensures smooth operation, long life & increased resistance to corrosion.
• Smooth & Linear Output: As voltage between turns is small and as the brush-arm is in constant contact with more then one turn, harmful sparking is avoided and output voltage can be set very easily to fraction of a volt from zero onwards by rotation of the knob.
• Low Magnetizing Current: By using an adequate section of high quality grain oriented silicon steel, the iron losses in Reguvolt, are controlled to the minimum. The no-load current in all Reguvolt transformers, is invariably less than 3% of the rated current.

Radiotone 0.5 A, 0.75 A, 1.2 A Single Layer Variable Autotransformers (colloquially known as Variac) are very small in size (82 mm Dia) Variable Autotransformers.  In same size we can also make from 0 to 25V at 5A or 0 – 50V @ 3A and for 400 Hz applications. Radiotone 0.5 A, 0.75 A, 1.2 A Single Layer Variable Autotransformers (colloquially known as Variac) are used in Instrumentation, HV Testers & Aviation (400 Hz).  All the models are coated for physical protection as shown in the picture.  We use Roller brushes for very smooth long lasting & arc free contact. 

leading Manufacturer Exporter of Variable Auto Transformer. Variable Transformer is known by different names in different countries such as continuously variable voltage auto transformer, variac auto transformer, variable transformer, variac transformer, voltage regulator, dimmer etc. Product ranges 2Ampere To 100Ampere. Products are available in single or 1 phase, three or 3 phase. Open Flush Panel Mounting type or floor mounting. Close Project Enclosed Types. Motorised variacs are also available.

We specialize in the manufacture of high current rated coils. The commutator surface of our coils is machine processed and hence very uniform and smooth. This is very important for proper collection of current by the carbon brushes thus reducing the heat generated. Our standard coils are 100 Amp, 150 Amp, 200 Amp. Using these coils we manufacture oil-cooled variautos from 100 Amp 3 Ph to 1200 Amp 3 Ph capacity (415 V input and 0-470 V variable output). In high current rated models we use multiple coils with properly rated balancing coils to achieve the rated current. Based on the calculations of cooling area appropriate no. of radiators &fins  are used. These variautos are generally motorized with geared mechanism. We also cater to tailor-made requirements.

We cater to a number of Manufacturing firms, Educational Institutes, Govt. bodies, as well as Resellers & Industrial Suppliers, providing equipment & solutions for their Test & Measurement needs. Features Rugged Construction. Excellent Regulation. High Efficiency. No Wave Form Distortion. Silver Plated Commutator. Low Operating Torque. Smooth Voltage Variations. Low Magnetizing Current. Negligible Maintenance and Trouble-Free Long Life.
