Frequently Asked Questions
What is a Three Phase Air Cooled Servo Voltage Stabilizer?
It is an automatic 3-phase voltage regulator that uses a microprocessor digital controller, motor-driven variac, and copper buck-boost transformer cooled by natural or forced air to supply constant 415V ±1% voltage.
What are the main advantages of Air Cooled stabilizers over Oil Cooled?
Air cooled stabilizers do not use transformer oil, eliminating oil maintenance, oil level checks, and potential leakage. They offer a compact footprint and are easier to transport and install indoors.
Can an air cooled stabilizer run continuously 24x7?
Yes. Hindustan Stabilizers air cooled models are rated for 100% continuous 24x7 duty cycle when operated within specified ambient temperatures and load capacity.
