A Voltage Stabilizer is a Voltage motor controlled stabilization system that performs optimum voltage supplier using a Buck\Boost transformer booster that captures voltage fluctuations from input and regulates current to the correct output. Costa power Industries Pvt. Ltd. is top seller for 3-phase Voltage stabilizer in Mumbai and voltage stabilizer in thane from 500VA to 750KVA successfully. Due motor adjust voltage clockwise and anticlockwise direction with components like control card, dimmer, comparator, transistor and mocs etc.

Costa Power suppliers Three Phase Stabilizers upto 600 KVA. We suppliers Air Cooled Voltage Stabilizer upto 300 KVA and Oil Cooled Stabilizers upto 1000 KVA. They are equipped with state of the art feedback control system to continuously monitor and correct the input voltage to provide constant output voltage. Our feature rich range of Servo Stabilizers are our most popular and cost-efficient offerings. Suitable for 95% of all applications, These Stabilizers guards against voltage fluctuations, protects against common harmful high-energy surges, transients and voltage spikes. We also have Models available in a wide Voltage range Correction. With independent phase control as standard on all three phase ranges, the voltage on each phase will always remain stable irrespective of load unbalance, even in situations where a 100% load imbalance may exist. Designed and built to comply with leading IS 985 standards they are offered with unparalleled technology.
