Suvik Electronics Private Limited

Range: 30 KVA to 2000 KVA (Higher KVA on request)

The
conventional torridal type stabilizers have demerits on maintenance,
efficiency as well as design limitations especially in higher KVA
units.  Hence, deployment of “Linear Stabilizer” is seen as the
ultimate solution.  Unlike conventional torridal stabilizers, linear
stabilizers employ vertical linear transformer instead the torridal
Variac.  Linear stabilizer are equipped with carbon rollers on both the
sides of coil.  Unlike the fixed type flat carbon brush used in
torridal Variac technology, the roller brush assembly gives high
reliability due to less ware and tear.  Linear technology employs heavy
section of electrolytic grade rectangular copper strip instead of
copper wire in order to minimize the losses and increase the efficiency
of equipment.  The core is built from grain oriented silicon steel
laminations which keep losses to minimum.  Linear technology is
suitable for 100% continuous duty along with the overload capability
for heavy starting load.

The new line of stabilizers are SUVIK's technological and innovative answer to voltage problem, indicating the ultimate stabilizing target. Today electric facilities can be supplied with voltage stabilized to the rated value for which they have been designed even in the presence of strong harmonic distortion.

'Suvik' series of voltage stabilisers offer a reliable and tested economic solution to inconveniences caused by voltage fluctuation. To use 'Suvik' SCVR is a real investment because the elimination of the inconveniences means a reduction in costs and an increase in productivity. Very often it is only necessary to avoid a few minutes machine downtime or just one failure to repay the cost of the stabilisers.

Precision fast-PWM ac mains voltage correction:

Normally,
Automatic voltage regulators (AVR) which are used in countries with
inadequate infrastructure and resources have failed to match pace with
the requirements of the sophisticated electronics it protects.  The
high-speed AVR recently developed by TSi Power Corporation and Romarsh
Ltd. is a boon to the industry.  The most prevalent technologies in use
are of the servo and tapswitching types.  And the most economical way
to mitigate problems is using a modern AVR.  It is the end user’s
responsibility to assess whether the main’s supply is of sufficient
quality to provide power for the sensitive equipment.  Again, the end
user has to select a proper solution that meets technical requirements.
 
Why VRp Instead of Other AVRs?:

Servo-motor
based or tap-switching AVRs are not suitable for sensitive load
equipment such as power supplies, rectifiers using solid-state devices
and air-conditioners, because of their slow response time and inherent
performance limitations. VRp precision PWM voltage regulators can be
used to protect any electronic equipment, particularly in countries
with inadequate infrastructures for the generation and distribution of
AC power. VRp is superior thanks to its fast 20 ms response time and
cycle-by-cycle voltage regulation without interrupting the load current.

The SSVR is designed to operate totally maintenance free and for continuous duty.  The static devices used are SCR i.e. Thyristors.  The system is capable of withstanding the thermal and the dynamic stresses resulting from internal and external short circuits as well as switching operations.  The topology of SSVR is based on the thyristors tap switching controlled by microcontroller.  The SSVR normally uses auto transformer with taps for regulation but on a need base auto transformer can be replaced by isolation transformer with taps on secondary winding.  Standard number of taps may vary from 4 to 7 regulation steps.  For better regulated output more steps can be used the transformer taps are switched through SCRs.  The switching mechanism of SCRs is controlled from output voltage feedback and a microcontroller based system to regulate the output voltage in desired band
