The SBW-ST series voltage regulator is a new generation of intelligent, fast, energy-saving regulated power supply tailored for users in industries such as refrigeration unit testing or large laboratories who require multi-level voltage adjustment and have specific electrical safety requirements. Based on our company's intelligent CNC compensated AC voltage regulator, it utilizes a single-chip microcomputer for intelligent control and features a multi-language LCD display, highlighting the equipment's safety, stability, energy efficiency, and user-friendly interface. Compared to traditional compensated voltage regulators, it boasts three significant advantages: intelligent control and display, rapid voltage stabilization, and quiet operation and energy saving. This dedicated voltage regulator employs a true RMS sampling circuit, accurately detecting the RMS value of various voltage waveforms, preventing electromagnetic and radio frequency interference, effectively filtering power grid pollution, and is equipped with an RS-232 interface for remote control, telemetry, and remote signaling functions. This dedicated voltage regulator for computer rooms also features comprehensive protection functions, ensuring the long-term safe operation of various computer centers and data centers under unattended conditions.

Protection |
Over-voltage | If the output line/phase voltage exceeds 10% above the set value, an alarm will be triggered, and the output will be disconnected after a 10-second delay. Note: Both the overvoltage threshold and delay time can be configured according to customer requirements. |
| Under-voltage | Undervoltage Protection: If the output line/phase voltage drops 12% below the set value, an alarm will be triggered, and the output will be disconnected after a 20-second delay. Note: Both the undervoltage threshold and delay time can be configured according to customer requirements. |
