The exceptional reliability and performance of the Elevator Intelligent Controller JT-3000C are not accidental. They are the result of a meticulous, multi-stage manufacturing and quality assurance process that adheres to the highest international standards, including ISO 9001 for quality management.
Component Sourcing & Incoming Quality Control (IQC)
Materials: We source only industrial-grade components from globally recognized suppliers (e.g., ARM processors, Infineon IGBTs, Panasonic capacitors). Process: Every batch of components undergoes rigorous IQC, including electrical testing and visual inspection, to weed out any potential defects before they enter the production line.
Multi-Layer PCB Fabrication & SMT Assembly
Materials: High-density, multi-layer FR-4 grade Printed Circuit Boards (PCBs) are used to ensure signal integrity and minimize electromagnetic interference (EMI). Process: Automated SMT (Surface-Mount Technology) lines place thousands of components per hour with robotic precision. This is followed by AOI (Automated Optical Inspection) to verify component placement.
Reflow & THT Soldering
Process: PCBs pass through a multi-zone reflow oven with a precisely controlled temperature profile to create perfect solder joints. Larger, high-stress components like connectors and transformers are then added via THT (Through-Hole Technology) soldering for maximum mechanical strength and durability.
Firmware Flashing & In-Circuit Testing (ICT)
Process: The core RTOS (Real-Time Operating System) and control firmware are securely flashed onto the processor. Each board then undergoes ICT, where a "bed of nails" tester checks thousands of points on the PCB to confirm every circuit is electrically sound and every component is functioning as intended.
Environmental Stress Screening (ESS) & Aging
Process: To guarantee a long service life (designed for >15 years, MTBF >100,000 hours), every controller is subjected to ESS. This involves a 48-hour "burn-in" test inside environmental chambers that cycle between extreme temperatures (-20°C to +60°C) and humidity levels, simulating years of harsh operating conditions to expose any latent weaknesses.
Final Assembly & Full Functional Test (FFT)
Process: The tested board is installed into its protective IP21 steel enclosure. A technician then performs a full functional test, simulating a complete elevator system. The controller must correctly respond to calls, manage door operations, activate safety circuits, and communicate flawlessly to pass this final gate.
Final Quality Assurance (FQA) & Packaging
Standard: A final QA inspector verifies all test reports, checks for any cosmetic blemishes, and ensures all accessories and documentation are included. The unit is then serialized for traceability and professionally packaged in anti-static, shock-absorbent materials for safe transit to our clients worldwide.

Frequently Asked Questions (FAQ)
Open-loop (VVVF) systems estimate the motor's speed and send a predetermined voltage/frequency profile. They have no feedback, so they can't correct for load changes, leading to jerky rides and poor leveling. Closed-loop vector control, used in the Elevator Intelligent Controller JT-3000C, uses an encoder for precise, real-time feedback on the motor's actual speed and position. The controller constantly compares the actual speed to the target speed and makes micro-adjustments, resulting in a perfectly smooth ride, precise speed regulation, and pinpoint landing accuracy regardless of the load in the car.
The JT-3000C is designed for maximum compatibility. It features:
• Dual CAN bus: For robust internal communication between the controller, car top, and landing operating panels.
• RS485: Supporting the Modbus RTU protocol, which is a common standard for industrial device communication.
• Ethernet (TCP/IP): For high-speed group control and seamless integration with modern Building Management Systems (BMS). It also supports Modbus TCP for easy data exchange.
• Optional 4G/Wi-Fi Module: For direct-to-cloud IoT connectivity, independent of the building's local network.
The JT-3000C achieves energy savings through a multi-pronged approach:
1. Regenerative Drive Compatibility: It seamlessly controls regenerative drives, which convert the elevator's braking energy (from a full car going down or an empty car going up) into clean electricity and feed it back into the building's grid.
2. Optimized Travel Profiles: The vector control algorithm calculates the most efficient acceleration/deceleration curve for every trip, minimizing peak energy draw.
3. Intelligent Standby: During idle periods, the controller enters a deep sleep mode, powering down non-essential components like cabinet fans and displays, significantly reducing standby power consumption.
4. Efficient Group Control: The dispatching algorithm minimizes the number of runs and empty trips, further reducing overall energy usage in a multi-car system.
Safety Integrity Level (SIL) is a measure of safety system performance, as defined by the IEC 61508 standard. It quantifies the risk reduction provided by a safety function. SIL 3 represents a very high level of safety performance, requiring extremely low probability of dangerous failure. For an Elevator Intelligent Controller JT-3000C, a SIL 3 rating means that critical safety functions (like preventing the car from moving with doors open, or stopping an overspeeding car) are implemented with an exceptionally high degree of reliability and redundancy, verified by a third-party certification body. It provides the highest level of assurance that the controller will perform its safety functions correctly when needed.
