The ALTEC three‑phase torque motor speed control module manual describes its voltage ranges, control inputs, wiring and dimensions.
This manual introduces the ALTEC three‑phase torque motor speed control module, which operates from 50‑380 V AC and provides a 12 V/150 mA DC power supply. It accepts control signals of 1‑5 VDC, 4‑20 mA or a 10 kΩ potentiometer and offers output voltages up to 520 VDC or 380 V AC.
The document includes electrical wiring diagrams for each control mode, details on dielectric strength (minimum 2500 V/50 Hz AC), and the module's physical dimensions. It also notes the need for heat‑sinking or fan cooling when driving larger motors. This manual is written in Chinese.
