Product Description

DK SCR series is a technology leading silicon controlled power controller. The product adopts leading OLED liquid crystal display technology and friendly UI man-machine interface. Using the modular design method, site maintenance and replacement is very convenient. High reliability and patented heat dissipation technology to ensure the reliability of the product for a long time. All the components are imported power components with first-class quality.

This product can be widely used in electric heating control. It can adapt to the heating control of resistive load, silicon-carbon bar, silicon-molybdenum bar, quartz lamp tube, graphite load and inductive transformer load. It is a good actuating unit for accurate temperature control. Products are widely used in petroleum, Chinese industry, medicine, glass, metal heat treatment, smelting and other industries.

This product has intelligent on-line distribution function, which can improve the impact of power grid. It has standard MODBUS RTU interface and optional PROFIBUS DP bus interface or MODBUS TCP communication. Performance beyond the import of similar products.

Product features
Power on slow start function, slow start time can be set to 0-360 seconds. It also has the function of easing off.

It has MODBUS RTU communication function and can be supplemented with PROFIBUS DP bus components to realize DCS field bus control.

It has the functions of SCR overtemperature detection, short phase protection of power supply and current limiting protection of precision transformer. It also has emergency stop function.

Load working voltage range is 100-690v.

Linear program control, no temperature drift output. Special anti-interference CPU is used to ensure the reliability of the system.

The equipment USES the flame retardant ABS enclosure and the internal device to improve the safety factor.

Adopt 12 - bit AD converter, realize more fine adjustment.

It has digital /OLED display function, which can display voltage, three-phase current, alarm code, etc., and can set parameter values locally.

Various load connection modes, star type neutral point connect zero, star type neutral point do not connect zero, triangle type connection, etc., can be set by parameters.

With advanced online distribution function, it can realize intelligent networking distribution control function, reduce the impact on the power grid and increase power factor.

Optional variable feed output function, various types of variable feed optional.

The product modules all adopt German original ximenkang products, the service life is longer.
