Malaysian UPS Markets
Frost & Sullivan, July 2007, Pages: 154
The Frost & Sullivan research titled Malaysian UPS Market provides identification and analysis key market drivers and restraints that are shaping the market currently, as well as discussion and analysis of key market changes and challenges that are impacting UPS sales prospects. In this research, Frost & Sullivan's expert analysts thoroughly examine the following UPS segments: Below 1 kVA, 1 to 5 kVA, 5.1 to 20 kVA, 20.1 to 50 kVA, 50.1 to 200 kVA, 200.1 to 500 kVA, and 500.1 kVA and above.
Market Sectors
Expert Frost & Sullivan analysts thoroughly examine the following market sectors in this research:
By Power Range:
- Below 1 kVA
- 1-5 kVA
- 5.1-20 kVA
- 20.1-50 kVA
- 50.1-200 kVA
- Above 200 kVA
Technologies
The following technologies are covered in this research:
- Standby (Offline) UPS: Here, electrical power flows from the power grid into the application, at the same time charging the battery. When not in use, the battery remains idle and does not interfere with the running of the application. When utility power fails, UPS system is kick started and power flows from the battery into the application, keeping it running even though it does not receive power from the power grid. Applications include personal desktops, small offices, and home offices. The topology of the standby (offline) UPS system is available in the below 5 kVa range.
- Line Interactive UPS: Here, electrical power flows from the power grid through a transfer switch and into an inverter, which is connected to the output of the UPS system. When the power grid fails, the transfer switch is opened and power flows from battery to the application. Line interactive UPS system also provides additional filtering and yield protection. This topology of UPS systems makes it the dominant type of UPS in the 0.5 to 5 kVa range, although it is available in the below 20 kVa range.
- Online UPS: On-line UPS systems are generally more expensive compared to the other two and are mainly sold in the 3 kVa and above power range. In on-line UPS system, the primary power path is to the inverter instead of from the power grid. The battery, along with a rectifier plays the major role in powering the application, even under normal situations. Power from the grid is double converted from AC to DC and then to AC again, thus effectively reducing all noises and harmonics that might be generated due to an unstable power supply. This provides a nearly ideal electrical performance.
