It is composed of a contact-type autotransformer voltage regulator, a servo motor, and an automatic control circuit. When the mains voltage is unstable or the load changes, the automatic sampling stabilizer control circuit sends a signal to drive the servo motor, adjusting the position of the autotransformer voltage regulator's carbon brush, so that the stabilizer output voltage is adjusted to the rated value and reaches a stable state.\r\n            <\/p>\r\n            <p class=\"mns-paragraph\">\r\n                This series of stabilizers features a lightweight structure and phase-by-phase voltage adjustment function. When combined with a step-up and step-down transformer, the product is very suitable for imported CNC numerical control machining systems, precision instruments, and other fine processing equipment with smooth current fluctuations. It is also suitable for office, lighting, and air conditioning environments in households. This series of stabilizers offers a wide variety of models, full specifications, and an attractive appearance. It features undistorted waveforms, high efficiency, reliable performance, and long-term operation. The stabilizer is equipped with short-delay, over-voltage, and other protection functions. According to user requirements, long-delay and under-voltage protection functions can also be added. It is an ideal economical voltage stabilizer, ensuring the normal operation of your electrical equipment.\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            <ol class=\"mns-list\">\r\n                <li>\r\n                    <strong>High-precision voltage stabilization, suitable for complex power grids<\/strong>\r\n                    Voltage stabilization accuracy \u2264 \u00b12% (adjustable 1%-5%), stable output for both single-phase and three-phase input, fast response speed (voltage change of 10% within \u2264 0.5s), smooth regulation without impact, suitable for scenarios with large voltage fluctuations and precision equipment.\r\n                <\/li>\r\n                <li>\r\n                    <strong>High efficiency and energy saving, stable operation<\/strong>\r\n                    Uses low-loss toroidal voltage regulator, efficiency \u2265 98% for models above 50KVA; microcontroller intelligent control, noiseless, long lifespan, supports manual\/automatic switching, convenient operation without frequent maintenance.\r\n                <\/li>\r\n                <li>\r\n                    <strong>Comprehensive protection, safe and reliable<\/strong>\r\n                    Features multiple protections such as overvoltage, undervoltage, and overcurrent; alarms with sound and light and disconnection of the circuit in case of abnormality; excellent insulation performance, strong overload capacity, can withstand instantaneous load shocks, double protection for equipment safety.\r\n                <\/li>\r\n                <li>\r\n                    <strong>Wide compatibility, convenient operation and maintenance<\/strong>\r\n                    Widely used in industrial, medical, and other fields, compatible with various devices requiring stable voltage; compact size, flexible installation, equipped with clear display interface for easy monitoring and maintenance, suitable for unattended scenarios.\r\n                <\/li>\r\n            <\/ol>\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>Input Voltage<\/th>\r\n                        <td>Single-phase160-250V<\/td>\r\n                        <td>Adjustment time<\/td>\r\n                        <td>When the 1S input voltage varies by 10%<\/td>\r\n                    <\/tr>\r\n                    <tr>\r\n                        <th>Input Voltage<\/th>\r\n                        <td>Three-phase277-430V<\/td>\r\n                        <td>Ambient temperature<\/td>\r\n                        <td>-10\u2103-+40\u2103<\/td>\r\n                    <\/tr>\r\n                    <tr>\r\n                        <th rowspan=\"3\">Output Voltage<\/th>\r\n                        <td>Single-phase220V and110V(0.5kVA-3kVA)<\/td>\r\n                        <td>Temperature rise<\/td>\r\n                        <td>&lt;60\u2103<\/td>\r\n                    <\/tr>\r\n                    <tr>\r\n                        <td>Single-phase220V(5kVA-30kVA)<\/td>\r\n                        <td>Waveform distortion<\/td>\r\n                        <td>No additional waveform distortion<\/td>\r\n                    <\/tr>\r\n                    <tr>\r\n                        <td>Three-phase380V<\/td>\r\n                        <td>Load power factor<\/td>\r\n                        <td>0.8<\/td>\r\n                    <\/tr>\r\n                    <tr>\r\n                        <th>Voltage Regulation Accuracy<\/th>\r\n                        <td>380(220)V\u00b13%<\/td>\r\n                        <td>Dielectric strength<\/td>\r\n                        <td>2000V\/1min<\/td>\r\n                    <\/tr>\r\n                    <tr>\r\n                        <th>Frequency<\/th>\r\n                        <td>50Hz\/60Hz<\/td>\r\n                        <td>Insulation resistance<\/td>\r\n                        <td>&gt;2M\u03a9<\/td>\r\n                    <\/tr>\r\n                    <tr>\r\n                        <th>Overvoltage Protection Value<\/th>\r\n                        <td>246V\u00b14V<\/td>\r\n                        <td><\/td>\r\n                        <td><\/td>\r\n                    <\/tr>\r\n                <\/thead>\r\n                <tbody><\/tbody>\r\n            <\/table>\r\n        <\/div>\r\n    <\/div>\r\n<\/body>\r\n<\/html>\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Home \u9875\u9762 S DBW H Three Phase Single Phase Voltage Stabilizer Customizable The S\/DBW-H series single-phase and three-phase high-precision fully automatic AC voltage stabilizers use a ring-type transformer disc structure for the voltage regulating system.
