2.Easy to operate
3.Guarenteed for one year against manufacturing defects
4.Efficient after sales service

Brief technical details

'RE' Variac Continuously Variable Auto Transformers usually form part of system in which other components such as transformers, Rectifier, Power supplies etc. are used as power components, 'RE' Variac Engineers are well experienced in such applications and are always available for consultation to prospective users,

The proportion between iron section and copper turns is such that at the maximum AC applied voltage maximum NO LOAD current is within 5%.

The insulation of the wire over one face is removed the output is taken between one end and the brush arm. The moving Brush contacts the next turn before it breaks away from the previous turn, thus there is no interruption in output voltage.

'RE' Variac is designed to Boost the Output, Voltage from 12% to 43% than the input voltage.

Three Single phase units are connected in star for 3 phase four wire system. The brush arms are moved by a common shaft and the Star point is connected to the neutral of the system. A Three phase voltage variable from zero to 470V. Custom made capacities can be manufactured and as yet the manufacturing range covers upto 2000 Amperes in three phase.

OPTIONAL:'RE' Variacs are available with motor drive. The type of motor used for driving is specially made for these application. It is 240V AC motor operating with speed of 60 RPM synchronous at 50Hz. It is instantly reversible and can be stopped without overun. It speed depends on frequency i,e.60 RPM at 50 Hz supply. The desired speed is obtained by suitable by gearing. It starts stops & reversed instantly. It is ideal for automatic voltage control through electronic system.

It can be stalled indefinitely without over heating.
