We offer quality Servo Controlled Voltage Stabilizer in Single Phase & Three Phase. These stabilizers work effectively under voltage fluctuations and aid in obtaining steady output. It is fast acting, and any variation in the supply, frequency, load and P.F. does not have effect on the output voltage setting. The important components of the stabilizer are made under strict quality control. Further, these stabilizers are used in different schools, homes, industries and other commercial sectors depending upon their load capacity.

Voltage Stabilizers Single & Three phase:

• All components sourced from reputed manufacturers, with confirmation to International standards as minimum prerequisite.
• 100% raw material and components inspection is done as per inward inspection manual. Individual assemblies and sub-assemblies also tested separately for higher reliability.
• Final equipment is tested for accelerated life test to identify and replace any weak links at QA.
• All electronic assemblies are tested on full load at 55° C in a oven for 48 hours to minimize failures.

Salient Features:
 

• Uses solid state control circuits, no relays, no warm-up time, for high reliability.
• Every unit is 'soak tested' for 48 hours. to ensure trouble free operation.
• Quick response time 10 milli sec (half a cycle).
  
• Synchronous motor drive for high reliability.
• All transformers are copper-wound on CR Iaminations and double vacuum impregnated for high efficiency, low losses and low temperature rise and to with stand for all climatic conditions,
• Excellent regulation as high as +/- 0.5%.
• Professional grade ICs and components. are l1sedfor high reliability.
• Introduces zero wave-form distortion.
• Plug-in type fiber glass PCBs with gold-plated fingers for better contacts to ensure excellent reliability minimum down-time.
