Welcome to Servo Stabilizer Kerala. We, the Sakthi ...transformer... an ISO 9001:2008 certified company have a good reputation as manufacturers and dealers of Servo Stabilizer. SERVO AUTOMATIC STABILIZER A step-down transformer is on whose secondary voltage is less

We are offering double wound auto transformer. Specially designed double wound autotransformer have been developed for voltage stabilizer application. These varistat is also available with inbuilt 12v dc motor, which is very cost effective and time saving for servo manufacturer. These varistat will eliminate the need of buck-boost transformer & ac or dc external motor, its gears , its couplings and other mechanical requirements in stabilizers.

Engineers, Scientists, Technicians working in laboratories on sensitive equipment 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 Engineering 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 Variable Autotransformer (colloquially known as Variac), followed by a 1: 1 Isolation transformer or vice versa. This combination becomes very bulky & heavy with two separate transformers or even with a combined box. It also occupies much of test bench space. This is more so with increasing current rating or VA. It also loses mobility. Radio Electric Pvt. Ltd. has solved this problem by designing Radiotone Double Wound Isolated Variable Autotransformer (colloquially known as Variac). This elegant & compact arrangement uses only ONE transformer on a single toroidal core. The Radiotone Double Wound Isolated Variable Autotransformer provides 2.5 KV Isolation between primary & secondary, primary & body with a Variable Output Voltage from 0V to the required voltage. Various models of Radiotone Double Wound Isolated Variable Autotransformer (colloquially known as Variac) are as Illustrated in the table. 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, 8A., etc). We also manufacture table-top models of Radiotone Double Wound Isolated Variable Autotransformer with various types of input/output sockets (Shuko / Dual type / Round type, etc) as required.

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".

It is recommended that every Isolation Transformer should have its own grounded earth, complete in itself.This is ensured by an Ultra Isolation Transformer (UIT). It provides for total electrical and electro static isolation with most effective screening of spikes, surges and transients. Further, it gives a true isolated local neutral and dedicated earth which are very essential for modern machines.
