According to different application fields, UPS can be divided into industrial UPS and commercial UPS.
Common UPS systems can be divided into two types, one is commercial UPS and the other is industrial UPS. Usually, commercial UPS will be used in information technology (IT) applications, such as computer rooms and data center environments, while industrial UPS systems are designed for critical process control, such as nuclear power plants or oil drilling platforms.
The difference between industrial UPS and commercial UPS:
1. Industrial UPS generally refers to the uninterruptible power supply used in key equipment in industries such as power, petrochemicals, and metallurgy. It usually uses phase-controlled rectification and high-frequency inversion technology.
2. Commercial UPS is used in data centers or computer terminals in insurance, finance and other industries. Most of them use high-frequency rectification and high-frequency inversion technology, and the mains, bypass, DC, and output are not isolated.
UPS power supply works in the environment:
Due to the poor use environment of general industrial UPS power supply, there may be special conditions such as dust, high and low temperature, high altitude, humidity, salt spray, acid mist, poor power grid, poor load, and poor electromagnetic interference, and the price is generally higher than commercial UPS power supply.
1. Industrial UPS power supply has a closed heat dissipation duct, which is isolated from electrical components to prevent dust from falling into electrical components.
2. Commercial UPS power supply generally does not have a special design for dust prevention, and parts generally do not have "three-proof" treatment.
Important industrial loads are usually powered by dual power grids, so industrial UPS power supply is designed with two AC power inputs (main AC power supply and backup AC power supply, also known as mains and bypass), and the two power supplies can be isolated from each other. The mains and bypass of commercial UPS power supply cannot be isolated and can only come from the same power grid.
Industrial UPS power supply systems are installed in harsh environments, but you can also see them in light industrial applications, such as pharmaceutical manufacturers or the food and beverage industry. In these environments, the loss of AC power may not cause dangerous situations, but the loss of product and production time can be very expensive.
Comparison between industrial UPS and commercial UPS:
1. Industrial UPS power system:
No critical load is dropped. Static switch cannot bypass power supply;
Design life: 20+ years Design life;
Ambient temperature range: 59 – 131°F (15 – 55°C);
Air humidity: 10 – 95% RH;
Air pollutants: usually very dusty and corrosive pollutants;
Manual bypass scheme: drum switch - zero point disconnection, independent of static switch;
Battery life: VRLA and flooding – 20 years;
Battery support time range: 60 – 480 minutes.
2. Commercial UPS power supply system:
Performance testing is usually not required;
Design life: 5-7 years;
Ambient temperature range: 73-95°F (23-35°C);
Air humidity: 10-55% RH;
Air pollutants: Pollutant content is usually very low;
Manual bypass solution: Circuit breaker only, static switch required for zero-crossing conversion;
Battery life: VRLA-5 years;
Battery support time range: 15-30 minutes.
Industrial UPS power supply and commercial UPS power supply production:
Industrial UPS power supply adopts order-based project production, 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 supply is generally mass-produced, and the cabinet color, cabinet size, communication protocol, contact signal, transmission volume, etc. cannot be customized according to the different needs of users.
