Core Industry Pain Points
(1) Critical Demand for Zero-Interruption Power Supply Key equipment such as train dispatching systemling systems, emergency lighting, and platform screen doors in high-speed rail, metro, and light rail systems require 24/7 uninterrupted power supply. Power outages from the ity grid can easily lead to train stoppages, passenger congestion, and significant social impact.

(2) Extreme Electromagnetic Interference Rail transit scenarios are subject to strong electromagnetic interce from high-voltage traction and high-frequency communication. Traditional industrial frequency UPS systems have weak interference resistance, making them prone to unstable output and shutdowns, which compromise operational y.

(3) Poor Environmental Adaptability Metro platforms and equipment rooms are confined spaces with issues such as vibration, dust, and humidity. Traditional industrial frequency UPS systems are bulky and have weak vibrationance, making installation difficult and resulting in high failure rates.

(4) Stringent O&M Requirements Rail transit operations are non-stop, requiring immediate response and rapid resolution for U Traditional O&M models suffer from delayed response times, failing to meet operational timeliness requirements and leading to the escalation of faults.

Corresponding Solutions
(1) High-Reliability Zero-Interruption Solution Adopts an N 1 redundant d with a Mean Time Between Failures (MTBF) ≥ 250,000 hours, paired with long-delay battery packs. It achieves a 0ms switch upon utility power nterruption, ensuring continuous operation of dispatch and signaling systems and eliminating the risk of train service disruption.

(2) Strong Electromagnetic Interference Resistance Solution Adopts a CC protection design to enhance electromagnetic interference resistance. It can withstand strong interferences from high-voltage traction and high-frequency communication in rail transit, with output voltage fluctuation ≤ ±uring stable equipment operation and safeguarding traffic safety.

(3) Compact Space Adaptation Solution Optimizes structural design to introduce miniaturized, rack-mounted models. The volums reduced by 35% and weight by 45%, making it suitable for installation in subway platforms and small server rooms. With a high IP protection rating, it can withstanration, dust, and humidity during operation.

(4) Emergency Maintenance Solution Establishes a 7×24-hour emergency maintenance team and deploys spare parts warehouses at key ss. The fault response time is ≤ 30 minutes, enabling rapid fault diagnosis and power restoration to minimize impact.

Scope of Application
It covers various rail transit operating organizations, including subways, light rail, intercity railways, and trams. It is adapted to core scenarios such as subway platform equipment rooms, traffic control centers, signaling equipment rooms, platform screen door control rooms, emergency lighting rooms, and rail transit monitoring centers, meeting the uninterrupted power supply requirements of various rail transit loads, including traffic control systems, signaling systems, platform screen door control systems, elevators, emergency lighting, and security monitoring equipment.
