Company profile

Tianjin Tiandi Dian Technology Co., Ltd. ("Dian Technology") is a power electronics innovator specializing in integrated AC/DC power systems and substation automation solutions. Our product portfolio encompasses intelligent power systems, emergency power supplies (EPS/UPS), DC panel monitoring systems, and maintenance-free batteries, complemented by comprehensive maintenance services. With proven expertise demonstrated in major projects for State Grid (220KV/110KV substations), industrial clients like Bohua Chemical, and international ventures including Indonesia's Central JAVA power plant, we combine technical excellence with a service-oriented approach. Guided by our "Three Supports" philosophy - resolving operational challenges, developing talent, and driving social impact - we implement rigorous quality control through scientific management. Upholding our core belief that "precision defines quality and service captures markets," Dian Technology is shaping China's power equipment landscape through reliable solutions across energy, industrial, and infrastructure sectors.

Main Product

In recent years, with the rapid development of electronics and communication technologies, substations and distribution stations have increasingly adopted microcomputer-based integrated automation control, placing higher demands on DC operational and emergency power supplies. Currently, domestically produced DC power cabinets can no longer fully meet market requirements, as many applications now call for enhanced automation and communication capabilities. Our company has developed a comprehensive series of power supply products to address these evolving needs. Leveraging patented "Resonant Voltage-Type Dual-Loop Control" technology—an innovative multi-resonant circuit design—we have achieved breakthrough full-range soft switching. Whether under no-load, light-load, or full-load conditions, both switching and rectifier transistors operate in soft-switching mode, significantly improving overall reliability. This technology fundamentally overcomes the limitations of traditional hard-switching and phase-shifted resonant soft-switching power supplies, fully harnessing the advantages of resonant circuit topologies.
