Introduction
Our company has developed the TH series intelligent high-frequency switching power supply modules, which employ active PFC power factor correction combined with digital LLC control. These modules offer advantages such as compact size, lightweight design,high efficiency, and high reliability. Each module is equipped with a standard RS-485 interface and features "four remote" capabilities,enabling real-time monitoring of the rectifier module status and load conditions, as well as remote adjustment of the output voltage.
System Performance Characteristics
- Modular design with N+1 hot standby, enabling seamless capacity expansion.
- The module features a standard RS-485 interface, facilitating integration with automation systems to enable "four remote monitoring" capabilities and unattended operation.
