• 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.

We are offering auto transformers. E have carved a niche as one of the dominant variac variable transformers exporters from india. “variac” auto transformers 1 ph. (closed open type) are designed to give output voltage of 260-270 volts for the input voltage of 240 volts. 3 phase “variac” auto transformers are designed to give output voltage of 470 volts for input 415 volts. these are available in manual and motorized operating type. features: continuously variable voltage auto transformers (variac) to obtain variable a.c. Voltage from a fixed a.c voltage to obtain established a.c. Voltage from a varying input supply in testing of electrical equipments where a gradually varying is a must to ensure non-destructive testing to eliminate the possibility of high surges for exact control of furnace and heater temperature

  Engineers, Scientists, Technicians working in laboratories on sensitive equipments have a need for Isolated mains supply, with a variable output Voltage. This facilitates them in testing various devices demanding different voltages & currents. It is also an Electrical Engg. practice to test devices by applying steadily increasing voltage from 0 V to the device rated voltage. To achieve the above objective, it is normal practice to use a Variauto followed by a 1: 1 Isolation transformer or vice versa as shown in figure 1. This combination becomes very bulky (heavy) with two separate transformers, wiring or a combined bulky box. occupying much of test test bench space. This is more so as the current rating or VA increasing. It looses its mobility. Radio Electric has solved this problem by designing a "Double Wound Isolated Variable Transformer". This elegant & compact arrangement uses only ONE Transformer on a Single torroidal Core. This provides 2.5 kv Isolation between prim & sec, prim & body with a Variable Output Voltage from 0V to the required voltage. Various models are as Illustrated in table 1.This concept can also be used very effectively in DC power supplies with Variable output (eg. Input 230V / 110 V, Output 0 to 25 V, 5A or 0 to 15V, 8 Amp. etc.). We also manufacture in table-top models with various types of input/output sockets (Shuko / Dual type / Round type, etc.) as required.       MODELS   Radiotone  DW  Isolated  Variable Transformer I/P 125 V, 60 Hz supply voltage & output Variable from 0 to 150 V
