According to different application fields, Uninterruptible power supply UPS can be divided into two categories: industrial grade ups and commercial ups.

There are two types of UPS systems, a commercial UPS system and an industrial grade UPS system. Generally, a commercial UPS will be found in Information Technology (IT) applications, such as computer rooms and data center environments, while Industrial UPS systems are designed for critical process control, like a nuclear power plant or an oil rig.

Industrial grade UPS

Industrial grade UPS power supply generally refers to the uninterruptible power supply used in key equipment in the power, petrochemical, metallurgical and other industries. It generally uses phase-controlled rectification and high-frequency inverter technology.

Commercial UPS

Commercial UPS is used in data centers or computer terminals in insurance, financial and other industries. Most of them use high-frequency rectification and high-frequency inverter technology, and the mains, bypass, DC, and output are not isolated.

The UPS working in environment

Due to the poor use environment of general industrial-grade UPS power supplies, there may be special conditions such as dust, high and low temperature, high altitude, humidity, salt spray, acid mist, bad power grid, bad load, bad electromagnetic interference, etc., and the price is generally higher than that of commercial UPS.

The industrial grade UPS power supply has enclosed heat dissipation ducts and is isolated from electrical components to prevent dust from falling into the electrical components.

Commercial-grade UPS power supplies generally do not have special designs for dust prevention, and parts and components generally do not have “three-proof” treatment.

Important industrial loads are usually powered by dual power grids, so industrial-grade UPS is designed with two AC power inputs (main AC power and backup AC power, also called mains and bypass), and the two power sources can be isolated from each other. The mains and the bypass of the commercial UPS cannot be isolated, and can only come from the same power grid.

Industrial UPS systems are installed in rugged environments, but you may also see them in light industrial applications, like pharmaceutical manufacturers or in the food and beverage industry. The loss of AC power may not present a dangerous situation in these environments, but the loss of product and production time can be very costly.

Compare Industrial UPS with Commercial UPS

 Industrial UPS SystemCommercial UPS System

Industrial-grade UPS power supplies are produced using an order project system, and the cabinet color, cabinet size, communication protocol, contact signal, transmission volume, etc. are customized according to the different needs of each user.

Commercial UPS power supplies are generally mass-produced on a large scale, and the cabinet color, cabinet size, communication protocol, contact signal, transmission volume, etc. cannot be customized according to the different needs of users.
