UPS， Full name: uninterrupted power supply. It is a constant-voltage, constant-frequency power supply device with an energy storage device (usually a battery) and an inverter as its main components. It is the "seamless switch" and "temporary generator" of power. Widely used in data centres and cloud computing, industry and manufacturing, the medical industry, and the communication and network industry.

When UPS is in operation, the rectifier, inverter, transformer (power-frequency machine), and other power components generate significant heat. The core task of the cooling fan is to remove heat from the cabinet in a timely and efficient manner through forced convection, ensuring that all electronic components operate within a safe temperature range. Ultra-high reliability and long service life, wide voltage and electrical compatibility, and environmental adaptability are the basic requirements for UPS fans. Schniro can provide standardized and customized solutions for the industry, with product sizes ranging primarily from 200mm to 400mm. Each size has different voltage configurations, designs and motor options.
