The TSD series alternating regulator is designed for regions with unstable power supply. It offers high efficiency, low voltage distortion, and continuous operation with full‑function protection, suitable for equipment such as copiers, computers, industrial electronics, medical devices, and household appliances. The regulator features over‑voltage and under‑voltage indication, protection, delay functions, and a DZ47 miniature circuit breaker for overload and short‑circuit protection.
The manual describes the regulator’s technical specifications, working principle, installation precautions, and maintenance procedures. It includes guidance on proper placement, grounding, safe handling, carbon‑brush replacement, and cleaning, as well as a parts list and warranty information. This manual is written in Chinese.

| Overload protection current (input) | 15 A / 25 A / 32 A |
| Voltage regulation accuracy | ±3 % (220 V), ±6 % (110 V) |
| Undervoltage protection threshold | > 184 V |
| Overvoltage protection threshold | < 246 V |
| Input voltage range | 150 V – 250 V |

When the input voltage or load changes, the sampling circuit measures the voltage, compares it with a reference, and the comparator drives a servo motor that moves the regulator arm and carbon brush to adjust the output, keeping it constant.
