Advantages

High-Quality Manufacturing and Strict Quality Control

The company ensures high-quality relay production through strict quality control, regarding quality as the lifeline of the enterprise. It continuously improves the quality management system and introduces international advanced production and testing equipment, ensuring each relay meets rigorous standards. The relays have passed ISO-9001 quality system certification and International Electrotechnical Commission IECO certification, demonstrating reliable quality and international recognition.

Diverse Types and Wide Application Scenarios

The company provides a diverse portfolio of relays, encompassing time relays, solid-state relays, intermediate relays, RXM relays, RM control relays, liquid level relays, and phase sequence relays. This variety enables their application in various electrical control systems, including industrial automation, power control, and liquid level control systems. Whether for signal amplification, circuit protection, or state detection, appropriate relay types are available to fulfill different customer requirements.

Precise Control and Signal Conversion Capability

Intermediate relays play a key role in control circuits by amplifying signals, increasing the number of contacts, and realizing signal conversion, enabling precise control of other electrical equipment. Phase sequence relays can accurately detect the phase sequence of three-phase power supplies and promptly issue signals or cut off circuits when phase sequence errors or phase loss occur, effectively protecting equipment safety. These functions make relays critical components for ensuring the accuracy and stability of electrical systems.
