1. Original Full-Model Compatibility & Lossless Replacement
Built-in exclusive Kaishan factory program is 100% compatible with all fixed-frequency and VFD screw compressors. The standard interface and wiring definition require no program rewriting, parameter calibration or circuit modification, supporting direct disassembly and replacement without startup failure, error reporting and program mismatch of ordinary universal mainboards.
2. PID Precise Intelligent Regulation & Energy Saving
Equipped with high-precision PID operation module, it dynamically collects pressure, temperature, current and voltage data, automatically adjusting unit loading, unloading and idle sleep according to air load. It accurately locks working pressure to eliminate pressure fluctuation and insufficient pressure, reducing invalid energy consumption and improving overall operation efficiency for continuous industrial air supply.
3. Bilingual Visual Operation & Global Versatility
Supporting one-key Chinese and English switching, the high-definition visual interface displays full operation data including pressure, temperature, running time, load status and fault codes. The user-friendly design with sensitive keys enables quick parameter setting, mode switching and fault query, suitable for both domestic factory operation and foreign trade export scenarios.
4. RS485 Remote Network & Unattended Intelligent Operation
Built-in standard RS485 industrial communication interface supports remote network monitoring, multi-unit centralized control and cloud data upload for unattended automatic operation. Managers can remotely check equipment status, fault information and working hours, reducing on-site inspection labor costs and meeting centralized management needs of multiple compressors in large factories.
5. Multiple Self-Locking Safety Protection & Equipment Safety Guarantee
Built-in full industrial-grade safety protection logic real-timely monitors equipment status, covering high temperature, pressure overload, phase loss, motor overload, abnormal oil circuit and delay shutdown. It automatically alarms and shuts down with self-locking and accurate fault code display when abnormalities occur, avoiding major faults such as head jamming and motor burnout caused by faulty operation.
6. Strong Anti-Interference & Stable VFD Operation
Optimized for high-frequency electromagnetic interference of VFD compressors with shielded circuit and anti-interference chip, it thoroughly solves common problems of ordinary controllers such as data garbling, parameter jumping, false start-stop and random alarm. Compatible with both fixed and VFD units, it delivers far higher stability than ordinary universal mainboards.
7. Industrial Durability & Harsh Condition Adaptation
Adopting flame-retardant dustproof shell and oil-proof moistureproof PCB circuit board, it resists dust, moisture, oil and aging, adapting to wide temperature range of -20℃ to 70℃. It operates stably 24/7 without stuttering, failure or program disorder in high-temperature, dusty and oily workshops with long service life and ultra-low failure rate.
