1.WLK-B is an economic excitation device with constant angle operation (manual increase or decrease of excitation), simple operation and maintenance, and contains basic alarm or trip protection such as lost step, underexcitation, phase loss, KQ misconductor.
2. WLK-T is an enhanced single system excitation device. Color touch screen display control, constant angle, constant excitation voltage, constant excitation current, constant power factor (automatically increase or decrease excitation, realize fully automatic unattended operation), independent selection of operation, PID adjustment of control settings, independent setting of excitation parameters, complete alarm or trip protection of excitation system such as lost step, underexcitation (upper and lower limit values can be set), overexcitation (upper and lower limit values can be set), phase loss, KQ misconductor, etc., operation Real-time historical display and query of operation parameters, real-time historical display and query of operation parameters curve, real-time historical alarm display and query, password login of parameter authority, 485 remote monitoring of backstage, and optional intelligent GPRS wireless control terminal for cell phone remote monitoring of site data according to user needs.
3. WLK-S is an enhanced dual system excitation device. The main circuit is an independent, complete, mutually isolated and standby double circuit; the control system is composed of two complete sets of control regulators, 10-inch color touch screen display control, constant angle, constant excitation voltage, constant excitation current, constant power factor (automatic excitation increase and decrease, to achieve fully automatic unattended operation) independent selection of operation, control settings PID adjustment, excitation parameters set independently, excitation system alarm or trip protection is complete. The system is fully protected by alarm or trip protection, such as out-of-step, under-excitation (upper and lower limits can be set), over-excitation (upper and lower limits can be set), phase failure, KQ misconductor, etc. 485 remote monitoring, and according to user needs, optional intelligent GPRS wireless control terminal, to achieve cell phone remote monitoring of site data."

Chengdu Hengda Industrial Control Co., Ltd, formerly known as Chengdu Hengda Chemical Self-Control Institute, was established in 1996, mainly engaged in the research and development of industrial automation products and production applications. We have independently developed microcomputer excitation control devices for synchronous motors, microcomputer excitation control devices for synchronous generators, microcomputer hydraulic control devices (applied to coal coke and natural gas production), voltage regulation devices (AC and DC voltage regulation), and microcomputer electrostatic dust removal control devices with independent knowledge production only. We have undertaken the design and transformation of industrial production process control and large assembly line process control, etc. For more than ten years, the company in line with the concept of quality as the basis of survival, integrity is the source of development, adhere to the high standards, refinement, zero defects in the road of intensive management, and constantly optimize product performance and improve the quality of after-sales service. With advanced management concept, strong financial strength, perfect technical support and after-sales service, the company has won the recognition and trust of our customers. The products are now spread all over mainland China, and exported to India, Chile, Russia and other countries, playing a vital role in safe production, energy saving and high efficiency for the cooperative enterprises. Chengdu Hengda is looking forward to working with you to create brilliance.
