AP series SCR power regulators have the characteristics of wide application range, multiple input signals, diversified control methods, comprehensive fault detection and alarm, current limiting protection, overcurrent protection, intelligent soft start/soft stop function, power regulation linearity, convenient power supply and two DC regulated power output.
The AP series SCR power adjuster offers a wide range of input signal options (0‑20 mA, 0‑5 V, 4‑20 mA, 1‑5 V, 0‑10 mA, 0‑10 V) and supports PID/PLC automatic control, manual control, and combined automatic/manual operation. It includes comprehensive fault detection such as phase‑loss, SCR breakdown, load open‑circuit, and over‑temperature alarms, with relay‑driven alarm signals and automatic current shutdown for equipment protection.
The manual details the main circuit wiring diagrams for each model family (AP1XX‑AP4XX), provides a full product catalog with current, power, dimensions, weight, and cooling information, and explains configuration of the six‑position DIP switch for input selection, phase/zero control, alarm settings, and soft‑start/soft‑stop timing. Environmental requirements, selection guidelines for resistive and inductive loads, and application notes for heaters, furnaces, and transformers are also included. This manual is written in Chinese.
