TAC60i is a high-precision three-phase power adjuster that combines three-phase voltage regulation and power adjustment. It features active triggering, phase-locked loop synchronization, automatic phase identification, power-on delay, gradual shutdown, overheating protection, current limiting, overcurrent protection, and serial operation indication. It is suitable for both resistive and inductive loads.
The TAC60i series is a high‑accuracy three‑phase power adjuster that integrates voltage and power regulation with active triggering, phase‑lock loop synchronization, and multiple protection functions. It is suitable for resistive and inductive loads in industrial heating, material processing, aerospace, metallurgy, and other applications.
The manual provides detailed information on product features, technical specifications, wiring diagrams, adjustment settings, safety precautions, and a parts list. Proper installation (wall‑mounted, vertical, well‑ventilated) and configuration of parameters such as start‑up time, current limit, and temperature protection are explained step by step. This manual is written in Chinese.
| Input voltage | 380V AC ±10% 50 Hz |
|---|---|
| Current capacity options | 50 A – 1500 A AC (multiple models) |
| Control board power supply | 220V AC, ≤0.5 A |
| Operating temperature range | 0 °C to +40 °C |
| Maximum humidity | 90 % RH |
| Start‑up time adjustment range | 0.2 s – 120 s |
| Current limit adjustment range | 20 % – 100 % |
Adjust the P3 potentiometer on the control board; the start‑up time can be set between 0.2 seconds and 120 seconds.
Turn the P4 potentiometer (or an external 10 kΩ potentiometer) to set the current limit between 20 % and 100 % of the rated current.
When an over‑current condition occurs, the three‑color status LED flashes red, indicating an over‑current alarm with no output.
