This manual introduces the basic features, installation, use and maintenance of the TTPR series three-phase thyristor power regulator.
This manual provides comprehensive guidance for the TTPR series three‑phase thyristor power regulator, including safety precautions, product specifications, installation, wiring, and operation. It also details the various control modes such as constant voltage, constant current, constant power, and phase‑shift control, as well as optional communication modules.
The document explains the standard MODBUS RS‑485 communication interface, wiring requirements, fault handling, maintenance procedures, and warranty information. It is intended for qualified personnel responsible for installation, commissioning, and service of the regulator. This manual is written in Chinese.
| Rated Current (model TTPR‑0025) | 25 A |
|---|---|
| Control Power Supply | AC 220 V ±15% |
| Analog Input Signal Range | 0‑20 mA, 4‑20 mA, 0‑10 V, 0‑5 V |
Installation must be performed by qualified personnel, the unit must be mounted on non‑combustible metal, kept away from explosive atmospheres, properly grounded, and power must be disconnected before wiring.
Use the standard RS‑485 MODBUS RTU port, connect shielded cables, and terminate each end with a 120 Ω resistor; do not directly short the communication pins.
