Automatic Voltage Regulation AVr SX460 technology provides automatic voltage regulation to deliver a stable output and protect electrical equipment from voltage fluctuations. Flexible SinglePhase Detection Featuring a copper function, this voltage regulator board allows you to select the detection voltage for singlephase 120/240VAC power supply, enhancing compatibility with various power sources. Loss Detection Protection A loss detection voltage protection circuit actively monitors voltage levels and triggers protective measures if power drops or is interrupted, safeguarding against power loss. Frequency Protection and Voltage BuildUp Includes frequency protection (UFRO) and voltage buildup functions to ensure stability and smooth operation by protecting against power disruptions and enabling a gradual voltage increase during startup. Use scenarios Home backup: maintains stable voltage for essential appliances and electronics during power outages. Worksite or workshop: supports portable generators powering tools and equipment with 120/240VAC, helping prevent damage from voltage swings. Small business or sensitive equipment installations: helps protect servers, CNC machines, labs, and other hardware that require reliable voltage regulation. Key benefits Improves electrical safety by regulating voltage levels and preventing fluctuations. Enhances compatibility with multiple 120/240VAC power sources through flexible singlephase detection. Provides protection against loss of power and disruptive power events, reducing equipment stress. Supports smooth startup and stable operation with dedicated voltage buildup and UFRObased protection.
