ABB uninterruptible power supplies: Light industrial UPS versus commercial UPS

ABB offers UPSs with different architectures, different features and a wide range of power capabilities. However, up until now, these UPSs have had one thing in common: They were designed for relatively friendly environments where the heating, cooling, ventilation and humidity are permanently controlled, and where there is no risk of biological attacks and very low levels of chemical contamination. Examples of such settings are control rooms or data centers in banks, hospitals, educational establishments, telecommunications hubs, server rooms, etc.

Of course, a large number of industrial settings are not so obliging when it comes to providing a friendly environment. Dust, moisture, vibration, excessive heat, corrosive air contamination, lack of space and manhandling are just some of the challenges that a UPS would have to face in industrial process plants, factories, electrical substations, oil and gas installations, and the like.

For this reason, ABB introduced, in 2016, a new modular UPS for use in these light industrial applications: The ABB PowerLine DPA UPS.

PowerLine DPA’s IP31-rated protection can easily cope with dust, water condensation, humidity (up to 95 percent), excessive heat, corrosive or biological air contamination and rough manhandling. The PowerLine DPA can provide power in the range of 20 kVA to 120 kVA and is designed to operate in a temperature range of -5 to +45 C without power derating.

When environmental conditions are not clean, risk can increase, so top priority has been given to the safety aspects and the UPS features a high degree of protection for users and maintenance staff. The ABB PowerLine DPA UPS has a robust mechanical design suitable for rough environments (water protection up to IP42, anti-corrosion treatment, anti-condensation heater, dust filter, etc) as well as an electrical design that protects against short circuit and overload; provides galvanic isolation up and downstream; employs halogen-free cables so no toxic gases are emitted in case of fire; and has a cold start capability in case of power blackout.

Lack of space is a problem frequently encountered in industrial environments, so the PowerLine DPA UPS has not only a small footprint but, unlike other ABB UPSs, also cable entry at the front (top and bottom), which eliminates the necessity for rear access and the associated extra space this entails. Ventilation flows from the front to the top, which means the UPS can be placed right up against a wall and lifting eyes support easy transportation and installation.

To ensure compatibility with the networking and distributed intelligence that is becoming prevalent in light industrial installations, the PowerLine UPS - like other ABB UPSs - can be supplied with relay boards and a network management card to allow environmental monitoring, extensive alarm handling and dispatching, redundant UPS monitoring, integration into multivendor and multiplatform environments and the supply of UPS data to Web applications.

The PowerLine UPS is similar to some other ABB UPSs in another way too: it is built on ABB’s unique and proven decentralized parallel architecture (DPA). The modular nature of DPA delivers not only the best availability but also the best serviceability and flexibility: Modules can be replaced without switching to bypass the whole system or powering off, so routine maintenance is simple.
