Relay Operated Voltage Stabilizer is meant to correct Low or High Mains Voltage and maintain the Load Voltage at ± 9 % of 230 or 240 Volts. Voltage adjustment is actuated by a combination of Relay operation and Transformer tappings thereby achieving an acceptable output voltage band.
Output is cut off automatically if the Input mains goes beyond the limits of its range. On start up, it has a time-delay function to protect the Compressor Motor against high in-rush current on restart immediately following a Cut-off or Mains failure. The Compressor Motor starts only after a time -delay of 2 to 3 minutes of Mains restoration. This function is especially useful where Power supply is erratic and switching on and off frequently.
These Stabilizers are suitable for small loads of 0.3 to 10 KVA. Relay operated Automatic Voltage Regulators (AVR's) or Stabilizers are mostly used in Residential / Small Istallations on Refrigeration and Air-conditioning equipment such as Window or Split AC's, Fridges, Water Coolers, Bottle Coolers, Ice-Cream Machines, Room Coolers, Dessert Coolers, Domestic Water pumps etc. The output voltage is maintained within a band of 205 - 245 Volts to protect the Compressor or Pump Motor. These AVR's are sometimes used on Small connection domestic Mains Supply also where cost is a prime consideration. However, it is recommended to use Servo Voltage Stabiliser on Mains supply.
ieco® is manufacturing full range of Automatic Voltage Stabilizers (AVR's) both Floor as well as Wall mounted type. High energy efficiency is achieved using selected high quality, Lo-loss materials. Toroidal transformers are specially designed to suppress Noise and Spike generation on switching. Full Digital Control using latest micro-controllers and software provide utmost reliability and precision.
ieco® Automatic Voltage Regulators (AVR's) or Stabilizers (also called, Automatic Line Voltage Correctors, Step type) are manufactured conforming to IS 8448: 1989 (Rev 2008). Considering high energy efficiency of ieco AVR's, user recovers its cost by way of substantial savings in Energy Bill - thus paying for its initial cost over a period of 2 to 3 years , making it virtually free later on -rather saving some net money.
