Power Testing Equipment

Power testing equipment refers to a specialized cluster of instruments used to verify, evaluate, and ensure the performance and safety of power equipment and systems. It mainly includes: Power Quality Analyzers (monitoring harmonics, flicker, transients, etc.), Relay Protection Test Power Supplies, Equipment Maintenance and Battery Testing Equipment, and Intelligent Discharge Testers, among others.

Power Supply Monitoring System

The PM6 Series Monitoring System is designed and developed in accordance with the requirements of the *State Grid Corporation of China’s 18 Major Anti-Accident Measures for Power Grids* and the industry standard *DL/T 1392-2014 Technical Specifications for Insulation Monitoring Devices in DC Power Supply Systems*. It provides a comprehensive set of solutions for the detection and control of AC power supplies, DC power supplies, communication power supplies, UPS power supplies, and various distribution circuits.

Power Module

The main function of a power module is to convert AC power into DC power and stabilize the output voltage. Since DC power can drive various electronic devices and electrical equipment, power modules play a crucial role in power transmission. Additionally, power modules also provide circuit protection functions, preventing issues such as over-voltage and over-current from occurring.

UPS Power Supply

UPS is an uninterruptible power supply that incorporates an energy storage device and uses an inverter as its main component to deliver constant voltage and constant frequency output. Its core function is to provide clean and stable AC power without interruption through batteries (or flywheels, supercapacitors, etc.) in the event of mains power interruption or abnormality.

DC EPS Power System

The DC EPS Power System is a centralized emergency power supply device primarily providing DC output. Under normal mains power conditions, it supplies power to loads through a rectifier while float-charging the battery bank. When the mains power fails, the system seamlessly switches via a static transfer switch (STS) to the battery bank for inverter output (or direct discharge), delivering emergency power that complies with national fire protection standards (such as GB 17945) to primary fire protection loads including fire emergency lighting, evacuation indicating signs, and emergency fans. It features fast transfer time, high safety, and centralized management.

Smart Lighting Power Supply System

The Smart Lighting Power Supply System is a digital power supply and control system based on power electronics, the Internet of Things (IoT), and intelligent sensing technologies. It not only delivers fundamental functions such as LED driving and stepless dimming (0-10V/DALI/PWM) but also enables Human Centric Lighting (HCL), energy consumption analysis, fault prediction, and coordinated group control through integration with Building Automation (BA) systems or cloud platforms. It serves as a critical component for achieving refined energy management in smart cities, green buildings, and smart factories.

Parallel Power Supply System

The Parallel Power Supply System achieves N+X redundant backup, power expansion, and load current sharing by connecting multiple power modules or complete units of the same or compatible models in parallel. Its core technologies include high-precision automatic current sharing algorithms, hot-swap design, and fault isolation mechanisms. This system significantly enhances system availability and maintainability, making it a standard configuration for high-availability scenarios such as substations, power plants, and industrial manufacturing.

Integrated Power Supply System

The Integrated Power Supply System achieves centralized monitoring, intelligent distribution, and unified operation and maintenance of power supplies through platform-level integration and deep convergence of DC operation power supplies, uninterruptible power supplies (UPS), inverter power supplies, communication power supplies, and battery management. It eliminates information silos found in traditional discrete systems, optimizes spatial layout, and enhances overall power supply efficiency and reliability, serving as the core power architecture for smart substations, power plants, data centers, and industrial critical facilities.

AC/DC Power Supply System

Platform Door Power Supply System

The Platform Door Power Supply System is a comprehensive power solution specifically designed to provide highly reliable power supply and control for platform safety doors/screen doors in rail transit. The system typically features dual mains power inputs with automatic switching and is equipped with a large-capacity battery bank as backup. In the event of a complete mains power failure, it ensures seamless switching to emergency mode, delivering continuous power to door drive units, control systems, and emergency operating devices—guaranteeing passenger safety and orderly station operations during train stops.
