Many companies are unprepared for business disruptions caused by power blackouts and are often unaware of the actual costs and impact that they can have on their operations. While the majority of power failures from national grids last only a few hours, some blackouts can last days or even weeks. This completely shuts down production […]

Uninterruptible Power Supplies (UPS) or UPS Systems as they are also known provide two important power solutions roles. UPS systems provide a source of standby back-up power when the mains power supply fails, and they also provide conditioning to remove mains borne power problems – sags, surges, brownouts, spikes and electrical noise. Power problems can lead to IT system […]

All three basic uninterruptible power supply (UPS) technologies have their place in protecting today’s distributed IT infrastructure especially on the network edge. Each technology has its advantages and each may be necessary for configuring cost effective power protection, especially in complex systems. Selecting a UPS for your particular application requires an examination of a number […]

There are four main components in any online double conversion uninterruptible power supply (UPS) system: Rectifier; UPS Batteries; Inverter; and Static Bypass Switch.   Rectifier   The rectifier carries out several key functions. The first is to convert the input power from AC (Alternating Current) to DC (Direct Current). Its second main role is to recharge the batteries, while the DC power routes to the […]

Uninterruptible Power Supplies (UPS) provide short-term emergency backup power in the event of any disturbances or disruptions to the mains electricity supply.   A UPS system protects computers, IT equipment, telecommunications networks, and other vital electrical equipment, infrastructure, and machinery against unexpected problems with the input power source.   Clean, continuous power is an essential requirement of 21st-century day-to-day life, with sectors as diverse as banking, utilities, manufacturing, transportation, […]

A three-phase (3-phase) UPS can deliver more electrical power than a single-phase (1-phase) supply because it uses the full three phases generated from the grid. Three-phase UPS tend to be used in industrial and business settings, whereas single-phase UPS systems are used for domestic appliances or equipment with lower power requirements. Single-Phase (1-Phase) UPS Overview Single-phase UPS have a single input and […]

At first glance, specifying an uninterruptible power supply seems a complex task. But in essence, whether you’re buying a new UPS system or replacing an existing unit, the choice boils down to two main factors: required load and battery autonomy.  To establish the required power consumption, separate out the critical loads (that will need protecting by the UPS) from the […]

Transformerless UPS systems were first developed in the 1990s and offered a number of benefits over traditional transformer-based systems in terms of higher efficiency, reduced size and weight, and cost savings.  Transformerless uninterruptible power supplies are now common in data centre environments and with smaller installations. They are the typical technology for the smallest power ratings (below 10 kVA) and are available up to around 300 kVA at the […]
