Size your Sunwin Rack Mounted Load Bank for data center rack density and airflow. Learn how voltage, load steps, and cooling capacity affect selection for reliable commissioning.

An aerospace power system generates, stores, converts, regulates and distributes electrical energy, and is typically divided into primary power and secondary power. Secondary power converts primary power into another form or specification to meet the requirements of different onboard electrical equipment. As an essential support system, the aerospace power system provides safe and reliable energy for every subsystem of aircraft and spacecraft, and its development level plays a decisive role in improving aircraft performance and extending service life.

From 28Vdc, 270Vdc to 400Hz AC supplies, power quality directly affects the safe operation of onboard equipment. International aerospace power quality standards such as MIL-STD-704 and RTCA DO-160 impose strict requirements on voltage, frequency and transient characteristics. Therefore, comprehensive testing and evaluation of the power system under defined operating conditions is of great significance.

With leading liquid-cooling technology, a complete product portfolio, precise real-working-condition simulation, one-stop solutions, international quality certification and a customer-first service philosophy, Sunwin will continue to safeguard the safety and reliability of power systems and AI computing infrastructure worldwide.

Qingdao Sunwin Technologies Co., Ltd. (Sunwin) is a professional enterprise dedicated to the R&D, manufacturing and service of intelligent power testing equipment. Built on load banks, Sunwin provides testing systems and intelligent test equipment for the generation, transmission, transformation, control and utilization of electrical energy.

A load bank is a power testing device that simulates real operating conditions (a dummy load). It reproduces the load characteristics of power equipment through resistive, inductive and other elements, enabling testing, adjustment, calibration and verification of generator sets, UPS, batteries and other power sources without connecting them to real loads. With advanced load testing technology, Sunwin helps customers scientifically verify the performance and reliability of power equipment, improve quality control and reduce safety accidents and economic losses caused by power failures.
