Automatic Voltage Stabilizer 15000w Single AC Voltage Regulator Wall-Mounted or Lay Flat 220V for Small Household Appliances

Product Information

This type of stabilizers is most popularly used for low rating appliances in residential, commercial and industrial applications as they are of low weight and low cost. Advantages of Relay type Voltage Stabilizers The Relay type Voltage Stabilizers normally stabilize the input fluctuations of ±15% with an output accuracy between ±5% to ±10%. Uses/ Advantages of Relay type Voltage Stabilizers Due to its Close loop property, Servo based Voltage Stabilizers used for appliances/ equipment which are very sensitive and need accurate input power supply (±01%) for performing intended functions. So the voltage stability and accuracy decide the correct operation of the equipment. Voltage stabilizers therefore ensure that the voltage fluctuations at the incoming power supply does not affect the load or electrical appliance. How Voltage Stabilizer Works? Basic Principle of Operation of Voltage Stabilizer

Output voltage varies about 1.2% for every 1% change in supply frequency. For example, a 2Hz change in generator frequency, which is very large, results in an output voltage change of only 4%, which has little effect for most loads. The overload protection feature allows the stabilizer to turn off the output completely in case of a short circuit or over the limit load. The concept of stabilization involves in adding or subtracting the voltage to and from the mains supply. Electronic voltage regulators are found in devices such as computer power supplies where they stabilize the DC voltages used by the processor and other elements. In automobile alternators and central power station generator plants, voltage regulators control the output of the plant. In an electric power distribution system, voltage regulators may be installed at a substation or along distribution lines so that all customers receive steady voltage independent of how much power is drawn from the line. Voltas is a leading brand in air conditioning and cooling solutions and offers a range of high-quality and affordable best stabilizer for AC . Some of the reasons to choose Voltas AC stabilizers are:Well.. both sound same. They both carry out the same function of stabilizing the voltage too. However, the way they do it brings the difference. The main functional difference between voltage stabilizer and voltage regulator is: Fig. 12 – Inner View of Three Phase Unbalanced type Servo Based Voltage Stabilizers Uses/ Advantages of Servo Based Voltage Stabilizer

Inverting terminalof the lower comparator is connected tothe referencevoltage and thepotentiometercorresponding to it is set to a voltage that is below the reference voltage(3.9 V) atthe non-inverting terminal. The electronic circuit board carries out the comparison of the Output Voltage with the reference voltage source. As soon as it detects any rise or fall in the input supply beyond the reference value, it starts operating the motor which further moves the arm on the auto-transformer. Generally, each and every electrical appliance is designed for a wide range of input voltage. Depending on the sensitivity, the working range of the equipment is limited to a specific value, for instance, some equipment can tolerate ± 10 percent of the rated voltage while others ± 5 percent or less. b. Add a safety margin of 20-25% to find the stabilizer rating. The more devices you wish to add, the greater is the safety margin. An expert can tell you the optimum number of devices to couple with the stabilizer.Since the stabilizers are rated in kVA, it is also possible to calculate the wattage by simply multiplying voltage of the appliance by maximum rated current. The output voltage can only be held constant within specified limits. The regulation is specified by two measurements: A digital display which can be LED/LCD shows input and output voltage, the temperature inside the stabilizer, current, status & the fault (if any) making the function of a stabilizer more reliable.
