Digital Intelligent Control

Compared with analog control systems, DSP-based intelligent induction heating power supplies offer higher stability under different environments. They can control IGBTs to operate in the optimal soft-switching state, optimizing parameters such as switching losses, voltage and current surges, and local temperature rise. This not only avoids the reduction in inverter efficiency caused by deviations from the optimal inverter state but also solves problems such as accelerated IGBT aging (e.g., unexpected damage after one year of use) and high later maintenance costs.

Ultra-High Precision Control

Adopting the second-generation high-performance precise algorithm-based power and frequency control technology, all control processes, data processing, parameter calculations, etc., are computed at high speed in the intelligent chip. The frequency tracking is free from loss of lock and drift, with a control precision reaching the nanosecond level. Combined with proprietary load matching testing technology, it can track and display the load matching status in real-time, ensuring the equipment always operates within the optimal power factor range.

Intelligent Protection

It is equipped with a rich set of fault judgment and protection circuits. In cases such as unstable cooling water pressure, excessive temperature, three-phase power phase loss, and cold workpieces touching the inductor (grounding protection), it can ensure that the power inverter stops outputting power. If the power supply suddenly encounters harsh working conditions during normal heating operation, it can judge various protection signals separately and issue fault alarms, such as overvoltage, overcurrent, frequency overrun, IGBT fault, etc., which can help users find and eliminate the fault source.

Sealing Protection

The use of sealing rubber strips combined with groove-type cabinet edges can achieve a high IP54 protection level. Dust, water vapor, oil fume, etc., cannot enter the interior of the cabinet. Even in harsh environments, it can be used for a long time, and the interior remains clean, ensuring that all electronic components always perform at their best.
