💡 Frequently Asked Questions
What is the main advantage of the SBW series stabilizer?
The SBW series offers large capacity, high efficiency, no waveform distortion, and stable voltage adjustment. It is built for long-term continuous operation under various load types.
Does this unit provide protection against power surges?
Yes, the input terminal is equipped with a high-energy surge impulse suppressor, which effectively protects the equipment from lightning induction and pulse spike voltages.
How fast can the stabilizer respond to voltage fluctuations?
The system has a response time of ≤ 100ms. When the input voltage jumps by 10%, the stabilization time is typically less than 1.5 seconds.
Can the output voltage be customized?
Yes, while standard inputs like 380V and 400V are common, the unit can be customized to support 440V or 480V based on specific industrial requirements.
What environments are suitable for this equipment?
It operates effectively in ambient temperatures ranging from -15℃ to +45℃ with relative humidity ≤90% and altitudes up to 2000m.
Is manual operation available?
Yes, the SBW series features free transferring between manual control and automatic control modes for maximum operational flexibility.
