The EBs are unable to keep pace with the power supply for the constantly growing demand by the industrial sector and housing sectors. Added to this, periodic variation in demand like peaking and sags gives rise to erratic voltage variations over the day. The neighbourhood of the industrial belt is subjected to violent Voltage fluctuations like Sags (Brown outs) when a big machine is switched ON, or a Surge when a big motor is switched OFF, which a servo stabilizer cannot correct. The causality of these highly fluctuating and noise ridden power supply are the expensive machines leading to huge loss of productivity added to the cost of repairs.

Protect your expensive machinery and equipment from these aberrations by installing Technohertz Static Precision Voltage Regulator (SPVR).

The salient features of the SPVR technology are

  • Its ability to correct sags and surges
  • It does not introduce any noise
  • Using high efficiency device like IGBT reduces loss and pays back faster
  • The need for periodic service is eliminated and its rugged design ensures very low down time
  • SPVR technology does not expose the sensitive load to the raw mains

Why Technohertz Static Precision Voltage Regulator?

Technohertz Static Precision Voltage Regulator is the state of the art product making use of the advantage of the latest high frequency device: Insulated Gate Bi-polar Transistor (IGBT). SPVR’s unique and high speed sensing circuit senses the voltage every 10 millisecond and corrects in the next 10 millisecond. Effectively the SPVR corrects the voltage within a cycle. This ensures almost a rock steady output voltage.

Added features:

Technohertz SPVR works much cooler and with greater efficiency. Ergonomically placed digital meter on the front of the regulator displays the input & output parameters with great accuracy.

The difference between other stabilizer technology and Technohertz Static Precision Voltage Regulator (SPVR) is shown below.
