Product details
Dual Adaptive Intelligent Operation System
Frequency Conversion Adaptive Function
The equipment is built with an intelligent frequency tracking system with an adaptive frequency range of 0.35kHz. No manual intervention or cabinet opening parameter commissioning is required during production process adjustment, workpiece specification replacement and load state changes. The power supply can independently identify the load resonance state, automatically complete frequency tracking and frequency modulation calibration, and match the optimal resonance frequency of the load in real time to maintain the optimal operating condition, reduce manual commissioning costs and avoid errors caused by manual parameter adjustment.
Variable Load Adaptive Function
The equipment has a full-process load adaptive matching capability. When facing working condition changes such as production process adjustment, load weight change and workpiece temperature change, it can independently complete the dynamic matching of power supply parameters and load states. The system corrects operating parameters in real time to keep the power supply and load in the best matching state, stabilize the equipment output efficiency, ensure the consistency of batch production quality, reduce equipment failure probability and extend the stable operation cycle of the equipment.

Precise Power and Temperature Control System
The IGBT Intelligent Power Supply Cabinet adopts a linked power and temperature regulation technology with a full digital automatic regulation system. The power supports 1%-100% stepless smooth adjustment without gear switching stagnation or output fluctuation. The system collects heating temperature data in real time, dynamically matches the output power, and automatically adjusts the power output according to the process temperature requirements, so as to realize accurate locking and stable control of heating temperature. This control mode effectively avoids over-temperature, uneven temperature and heating lag, meeting the requirements of high-precision quenching and tempering heat treatment processes.
High Power Factor Energy-Saving Performance
The equipment is adaptable to all working loads. The power factor remains higher than 0.95 under conventional working conditions with power output ≥50%. No independent power compensation device is required, which directly reduces users' equipment procurement and installation costs. The high power factor operation mode effectively improves the overall power supply capacity of the factory power supply system, suppresses high-order harmonics generated during equipment operation, optimizes power quality, reduces reactive power loss and enterprise electricity costs, and realizes long-term energy-saving operation.
High-Reliability Start and Operation Performance
The start performance of the equipment is not affected by load states and workpiece temperature states. It can realize 0.2-second ultra-fast start under all working conditions including no-load, full load, cold workpiece and hot workpiece. Adopting standardized program control, the equipment achieves a 100% start success rate and 0.1% operating parameter repeat accuracy. It can maintain a stable output state for a long time, adapt to 24-hour uninterrupted industrial production line operation, and avoid production delays caused by start failures and parameter drift.
Multi-Mode Closed-Loop Control Function
The equipment supports three switchable closed-loop control modes: constant power control, constant temperature control and constant current control (optional functions). The multi-mode closed-loop control can adapt to working conditions of different metal materials, heating processes and production rhythms, accurately meet the process requirements of workpiece preheating, heating, quenching and tempering, and heat preservation, and improve the universality and adaptability of the production line.
