and developed by our company in response to the current situation of China's national power grid. They can automatically maintain a stable output voltage when external power supply network voltage fluctuations or load changes cause voltage variations. Compared with other types of voltage regulators, this series of products has the advantages of large capacity, high efficiency, no waveform distortion, and stable voltage regulation. They are suitable for a wide range of loads, can withstand instantaneous overload, can work continuously for long periods, support manual\/automatic switching, and are equipped with overvoltage protection, phase loss, phase sequence protection, and automatic mechanical fault protection. The machines are reliable in operation, compact in size, lightweight, and convenient to use and install. This series of products has passed the European Union 'CE' certification and obtained authoritative testing from the Shanghai Testing Center certification authority, and can be used interchangeably with foreign products.\r\n            <\/p>\r\n        <\/div>\r\n\r\n        <!-- Core Advantage -->\r\n        <div class=\"mns-card\">\r\n            <div class=\"mns-section-title\">Core Advantage<\/div>\r\n            <ul class=\"mns-list\">\r\n                <li>High voltage regulation accuracy: Uses an RMS true value sampling control board, with adjustable voltage regulation accuracy from 1% to 5%.<\/li>\r\n                <li>Fast adjustment speed: Machine tool slide conduction technology, response time \u2264 0.04s, stabilization time <1.2s.<\/li>\r\n                <li>Comprehensive protection features: Equipped with overvoltage, undervoltage, overcurrent, short circuit, overheat, phase loss, and other protection functions.<\/li>\r\n                <li>Wide voltage regulation range: Standard \u00b115%, customizable range \u00b120%~\u00b150%.<\/li>\r\n                <li>High overall efficiency: Regulator efficiency \u2265 98%.<\/li>\r\n                <li>Stable control technology: Advanced MCU measurement control, imported metering chip design technology, system precise and stable.<\/li>\r\n                <li>Excellent output waveform: Output voltage waveform distortion-free, no harmonics.<\/li>\r\n                <li>High-quality materials: 0.35mm high magnetic conductivity, low-loss coated silicon steel sheets, C1017 alloy brushes.<\/li>\r\n                <li>High degree of automation: System fully automatic voltage regulation, delayed start, fault recovery automatic restoration functions.<\/li>\r\n                <li>Large load capacity: Regulator capacity selectable from 1kVA to 3600kVA.<\/li>\r\n                <li>Wide load compatibility: Suitable for any load.<\/li>\r\n                <li>Comprehensive communication functions: RS485\/RS232\/GPRS optional.<\/li>\r\n            <\/ul>\r\n        <\/div>\r\n\r\n        <!-- Technical Parameters Table -->\r\n        <div class=\"mns-card\">\r\n            <table class=\"mns-table\">\r\n                <thead>\r\n                    <tr>\r\n                        <th>Capacity range<\/th>\r\n                        <td>Three-phase capacity SBW-20-3600kVA;
