The ZK1000 series single-phase SCR AC regulator adopts a dual closed-loop control, the current loop is the inner loop, and the voltage loop (or power loop) is the outer loop. The stability of output voltage, current or power is high; the option of constant voltage (constant output voltage), constant current (constant output current), and constant power (constant output power) can be selected by the rotary switch; it has overcurrent, overheating and other protection functions; the input adopts linear optical coupling devices for isolation; the given parts, the regulating parts, and the thyristor circuits are electrically isolated, have strong anti-interference ability, and have high safety performance; voltage, current, and power are output (DC0～10V, three choices); it is suitable for resistive loads and inductive loads; the control board adopts advanced SMT technology, and the reliability is high.
This manual introduces the ZK1000 series single‑phase thyristor AC voltage regulator, highlighting its compact design, dual‑loop control, selectable constant‑voltage/current/power modes, and built‑in over‑current and over‑heat protection. It also lists the environmental and certification details for reliable industrial use.
The document is organized into sections covering safety precautions, product information (model definitions, nameplate, technical parameters, dimensions), installation and wiring procedures, operation instructions, control principles and functions, fault handling and maintenance, and appendices with warranty forms and feedback sheets. This manual is written in Chinese.
