We are offering transformer. Double wound, step-down transformer made from high quality annameled dpc copper wire of circular & square cross selection & having crgo lamination as core. Transformer core is cylindrically designed to overcome losses and achieve maximum efficiency high packing fraction enables compact transformer design & reduces heating in high load condition ballast choke is single wound inductor made of crno lamination &anameled copper wire set to perfection to controll current & voltage drop at perticular current load. Setting only possible at factory.

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.
