UPS Solutions UPS Solutions

With its wide range of Uninterruptible Power Supplies (UPS), Delta offers a competitive edge to businesses in need of first-rate power solutions. Delta UPSs are designed to ensure that companies can protect their mission critical applications by maintaining a steady flow of energy under adverse circumstances. An uninterruptible power supply is an electrical apparatus designed to furnish emergency power even when other sources of input power fail, and they are indispensable tools within a huge number of unrelated industries. These devices differ from a standby generator or an auxiliary or emergency power system in that in the event of a disruption to input power, a UPS will provide near-instantaneous protection for mission critical applications in the form of energy stored in batteries.


The high cost of electricity is not a factor that businesses can afford to ignore when considering their overhead. Every company, no matter how large or how small, must monitor its power use in order to avoid consuming too much. Delta UPSs are known for efficiency and for saving not just energy, but money that would be wasted by less advanced devices that require too much power.


The growth of a business should never be at risk of limitation or delay due to avoidable technical restrictions of existing power hardware. To help companies prepare for increasing success, Delta engineers flexible, scalable systems that are built to be easy to expand as needed, to accommodate greater demands for power protection.

Advanced power electronics equipment applications can improve our work efficiency and make life easier, but at the same time they can pollute the power grid. Rectifiers play a large part in many applications that are growing faster than power grid construction. Voltage and current harmonics, reactive power fluctuation, three phase imbalance, and other issues are caused by rectifiers with power quality issues that threaten the reliability and efficiency of the power supply system. Similarly, power voltage amplitude and frequency issues are affected by power generation.


We need to eliminate grid harmonics, reactive power fluctuations, imbalance, and other issues to adapt to new electronic equipment and power quality problems.

Telecom Power Solutions Telecom Power Solutions

Telecom power systems secure telecommunication services in case of grid power interruptions and fluctuations. Delta’s power systems are designed for wireless broadband access and fixed-line applications, as well as for Internet backbone and data centres. We provide a broad range of power systems and global services to telecom operators, network manufacturers and integrators.


The essential parts of a system are rectifiers, batteries and a power system controller. In direct current (DC) power systems, a rectifier converts alternating current (AC) to DC and provides the power necessary to charge batteries. In AC power systems, an inverter converts DC into uninterruptible AC. A power system controller monitors and controls the entire system and site power infrastructure, maximizes battery life, supports energy and cost savings, and informs the operator of maintenance needs. The power system can be expanded with renewable energy sources, which creates major energy and operating cost savings. In regions with highly unstable AC mains conditions, additional AC line conditioning elements can be integrated into the system for optimal operation.


Delta’s InD, OutD and HelpD series are designed to complement each other. InD stands for indoor power systems, while OutD solutions are designed for demanding outdoor use. HelpD is our global service concept. Our CellD and CabD series are designed to fulfil all your power requirements.

Precision Cooling Precision Cooling

In order to offer the best possible space utilization, and to accommodate the potentially rapid expansion of new IT equipment, modern data centers have implemented a high-density model, based primarily on blade server technology. This model requires a higher power supply density, and can thereby create more significant problems with heat dissipation. In order to address these issues, round-the-clock air conditioning is sometimes deployed as a cooling system solution. However, the expense of using this method for data center cooling can end up accounting for up to 45% of the total electricity expenses incurred by the data center. With this in mind, heat dissipation and electricity expenses are important indices against which operational expenditures of the data center can be measured.


As a leading global manufacturer of fans and a specialist in power management, Delta Electronics was perfectly positioned to develop Delta InfraSuite Precision Cooling solutions in order to provide practical, optimized, innovative methods for data center cooling. Delta’s precision cooling enthalpy laboratory carefully verifies cooling system performance and reliability during the engineering development and design process to ensure high product performance.


Specialized forms of air conditioning and temperature control have been developed to cater to the unique cooling system needs of contemporary data centers. Traditional precision air conditioning is not appropriate in many cases as a data center cooling system. This type of air conditioning cannot provide adequate heat removal for data centers due to the problems of uneven heat distribution, load variations experienced during peak and off-peak periods, and high power density. An optimal data center cooling system must accommodate for each of these factors. Instead of traditional precision air conditioning methods, Delta InfraSuite Precision Cooling solutions employ either chilled water or refrigerant types to remove the heat produced by the hardware within the data center.


Cooling units can be installed in a modular rack design, which enables quick configuration and is readily expandable by load. Data center cooling by water is safe for the equipment it protects due in part to built-in leakage detectors, which can display leaks and offer alerts in a timely manner. With manual dehumidification capacity, Delta’s data center cooling system offers a rapid and precise means of adjusting the level of moisture within the air, and keeping humidity levels within the ideal range required by the data center equipment.
