Frequently Asked Questions
What is a Three Phase Oil Cooled Servo Voltage Stabilizer?
A three phase oil cooled servo voltage stabilizer uses a motorized variable auto-transformer (variac), buck-boost transformer, and digital microprocessor controller immersed in insulating transformer oil to continuously adjust and balance incoming voltage to a steady 415V ±1% output.
When should I choose Oil Cooled over Air Cooled servo stabilizers?
Oil cooled servo stabilizers are recommended for capacities above 30 kVA, continuous 24x7 heavy industrial operations, outdoor or dusty factory environments, and high ambient temperature locations due to superior heat dissipation provided by transformer oil.
Is the stabilizer suitable for CNC machines and VMC equipment?
Yes. Our oil cooled servo stabilizers maintain ±1% regulation with zero waveform distortion, protecting sensitive CNC controllers, servo drives, and spindle motors against voltage sags and spikes.
What input voltage range can be customized?
Standard 3-phase input ranges are 340V–460V AC. Customized wide input ranges such as 300V–460V or 240V–460V AC can be supplied upon request based on your local utility grid conditions.
Need the Right Voltage Stabilizer for Your Application?
Provide your total load capacity (kVA or HP), incoming voltage window, and application details. Our engineering team will recommend the optimal oil-cooled configuration.
