Converter product series
Product Overview
The converter is the energy conversion unit of a wind turbine and serves as the control center of the entire electrical system. It directly affects key electrical parameters and functions, such as power generation efficiency and low-voltage ride-through capability, while also exchanging multiple types of real-time data with the turbine’s main controller.
Rack-mounted air conditioner
Product Overview
High-efficiency outdoor wall-mounted cooling units with cooling capacities ranging from 600 W to 4,000 W. Rated to NEMA 250 Type 3, they operate within an ambient temperature range of –40°C to 55°C, ensuring optimal protection even under harsh environmental conditions. These units are designed for external mounting and include auxiliary mounting hardware.
Micro‑Wind Series Industrial and Commercial Liquid‑Cooled Energy Storage Products
Product Overview
The 125 kW/261 kWh liquid‑cooled energy storage cabinet is a highly integrated, turnkey energy storage solution designed specifically for industrial and commercial applications. The system incorporates lithium‑iron‑phosphate batteries, a bidirectional power conversion system (PCS), a battery management system (BMS), an energy management system (EMS), a full‑liquid‑cooling thermal management system, and multi‑level fire‑protection features. It eliminates the need for separate component assembly, featuring a prefabricated, all‑in‑one design that supports rapid grid connection and plug‑and‑play operation, significantly shortening construction timelines and reducing site‑related costs.
IT Modular Unit
Product Overview
It integrates a complete suite of MEP systems, including IT cabinets, air curtains, row‑end cabinets, cooling pipelines, power and low‑voltage ladder racks, fiber optic raceways, lighting, sensors, and security monitoring. On site, only water, electricity, and network connections are required for modular commissioning. The entire process is factory‑prefabricated and pre‑tested, with full‑cabin integration and system‑level testing completed before shipment, enabling week‑long deployment. Featuring a modular architecture, it supports elastic scaling and facilitates phased capacity expansion for data centers.
