Core Product Advantages
| High-Precision Temperature Measurement + Comprehensive Protection – Fortifying Equipment Safety (Addresses the "Safety & Compliance" Challenge) Utilizing high-precision Pt100 sensors , our Transformer Temperature Controller system monitors winding, core, and ambient temperatures in real-time. With Class 0.5 accuracy and 0.1°C resolution, it detects subtle temperature changes, providing early warning of potential risks. The system features a complete closed-loop logic from warning to protection: it automatically activates fans and triggers audible/visual alarms during overtemperature conditions, and can initiate trip protection in critical situations. Built-in sensor self-diagnosis effectively prevents malfunctions caused by signal faults. This creates a dual safety net for hazardous industrial environments-preventing equipment damage from overheating while ensuring the protection system itself remains consistently reliable. |

Intelligent Automated Control – Empowering Cost Reduction and Efficiency Gains (Addresses the "Operational Cost" Challenge) Through high-performance hardware and intelligent algorithms, we enable automatic start/stop and precise coordinated control (1-6 circuits) of cooling fans. The unique timed fan excitation function helps prevent bearing seizure, extending fan life while reducing energy consumption. This automated system handles the entire process from monitoring to regulation, significantly minimizing manual intervention. It is particularly suited for unmanned substations and remote renewable energy sites, substantially lowering on-site maintenance costs while boosting management efficiency and reliability. |
| Strong Anti-Interference + High Reliability – Adaptable to Complex Industrial Environments (Addresses the "Environmental Adaptation" Challenge) We understand the complexity of industrial settings. Therefore, our design incorporates dual hardware and software-level anti-interference measures, ensuring the device passes stringent IEC and national EMC certifications. This means stable, precise operation is maintained even under harsh conditions with strong electromagnetic interference, high temperature/humidity, or excessive dust. Combined with a rugged enclosure and an MTBF exceeding 20,000 hours, it offers not just broad installation adaptability but also long-term, maintenance-free peace of mind and significantly reduced total lifecycle operational costs. |

Digital Operations + Flexible Compatibility – Facilitating Smart Management Upgrade (Addresses the "Digital Transformation" Challenge) Intelligent operations begin with seamless data connectivity and reliable traceability. Our temperature controller features a standard RS485 interface and Modbus-RTU protocol for quick integration with your existing systems and centralized remote management. Its built-in "black box" function accurately logs data during critical events like power outages, providing reliable evidence for fault analysis. The product is compatible with mainstream models and allows for simple installation and wiring, enabling direct replacement of outdated equipment. All these features are designed to help you take the crucial step towards operational digitalization with minimal upgrade costs, significantly improving management efficiency and system reliability. |

Traditional temperature controllers offer only basic monitoring and post-event alarms, functioning essentially as passive "thermometers." Our Transformer Temperature Controller, however, is designed to be your on-site "Intelligent Safety Guardian." Through high-precision sensing, intelligent algorithms, and digital connectivity, we enable full-cycle proactive management-from early warning and regulation to data analysis. This approach not only more effectively prevents equipment damage from overheating but also transforms temperature data into operational insights. It helps you enhance management efficiency, reduce overall costs, and fundamentally shift from reactive response to proactive protection.
Core Technical Highlights: Four Key Capabilities Powering the Solution

Supports mainstream industrial communication protocols like Modbus-RTU, enabling seamless integration into customers' existing control systems without the need for additional communication networks, thereby lowering the barrier to digital upgrades.
Ensures stable and reliable operation throughout the device's entire lifecycle-from sensors and enclosure to hardware interference resistance and software fault diagnostics-reducing maintenance costs.
Frequently Asked Questions (FAQ)
Q: 1. Our Transformer Temperature Controller is an older model. Can this controller be a direct replacement?
A: Yes, absolutely. This product is fully compatible with mainstream legacy controller models in the industry (e.g., BWD-326EF, BWDK-3K130). It features standardized mounting dimensions (e.g., the common 310mm×220mm×70mm size) and terminal blocks for simple wiring. We provide free installation guidance. No modification to the transformer itself is needed-it's a direct replacement, significantly lowering your upgrade costs.
Q: 2. Will the temperature measurement accuracy be affected in workshop environments with strong electromagnetic interference (EMI)?
A: No. The product employs a dual-layer anti-interference design combining hardware shielding and software filtering. It has passed IEC61000-4 international EMC testing, effectively resisting strong EMI prevalent in industrial settings. In practical applications, even near high-power motors or frequency converters, measurement accuracy remains within Class 0.5, ensuring reliable temperature monitoring and protection.
Q: 3. The product supports remote monitoring. Does it require additional software?
A: No proprietary software is needed. The product supports the standard Modbus-RTU industrial protocol and can connect directly to your existing SCADA, DCS, or other control systems. If you do not have an existing system, we provide user-friendly, complimentary PC monitoring software for basic remote management needs, including real-time temperature viewing, parameter setting, and alarm log queries.
Q: 4. How does the controller handle a sensor failure? Could it cause the transformer to become uncontrolled?
A: It will not lead to a loss of control. The product features comprehensive built-in sensor fault detection. In the event of an open or short circuit, it immediately displays a fault code on the panel, triggers audible/visual alarms, and automatically disables fan control and trip outputs to prevent erroneous actions. Furthermore, we offer an 18-month warranty. Should a sensor fault occur, we provide a free replacement and troubleshooting guidance.
Q: 5. How should temperature thresholds be set for different scenarios? Can you provide customized solutions?
A: We provide standardized threshold recommendations (common settings: Fan Start at 100°C / Stop at 80°C; Overtemp Alarm at 130°C; Overtemp Trip at 150°C) based on your transformer model, capacity, and application (e.g., industrial workshop, renewable plant, data center). We also support customizing threshold parameters per your specific requirements. For large projects or complex scenarios, we offer on-site surveys to deliver tailored full-scope solutions, including sensor placement planning, communication architecture design, and operational workflow optimization.
