UPS Technology

Why have a Strategy for Uninterrupted Power?

A clean, continuous power supply is essential for today’s business environment. Power failure can mean downtime, reduced productivity, irrecoverable data and lost revenue.

Unfiltered electricity can mean disturbances in system operation and processes and even damage to sensitive electronic equipment.

With a back-up power strategy in place you will always have emergency power in the event of mains supply failure and a filtered regulated power supply limiting the detrimental effects of electrical disturbances.

Why use UPS?

Based upon three main UPS topologies, NSSE offers a wide range of UPS solutions to provide an appropriate level of power protection against different power problems and failures.


Passive Standby (offline) solutions

Passive Standby (offline) solutions supply power to the application directly from the mains, filtered but without active conversion. The battery is charged from the mains. In the event of a power cut or fluctuation, the UPS delivers stable power from the battery. The advantages of this topology are low cost and adequacy for office environments. Passive standby solutions are not suitable if the power supply is of low quality (industrial sites) or subject to frequent disruptions.


Line interactive topology

Line interactive topology is used for protecting networks and IT applications against power failure, power sag, power surge, undervoltage and overvoltage. In normal mode, the device is controlled by a microprocessor that monitors the quality of the supply and reacts to fluctuations. A voltage compensation circuit is enabled to boost or reduce the supply voltage to compensate for the fluctuations. The main advantage of this technology is that it enables compensation of under and overvoltage without using the batteries.


Double Conversion topology (on-line)

Double Conversion topology (on-line) is a basis for UPS systems designed for continuous power protection of critical equipment against all nine power problems: power failure, power sag, power surge, undervoltage, overvoltage, switching transient, line noise, frequency variation and harmonic distortion. It ensures a consistent quality of power supply regardless of disturbances in the incoming mains. The output voltage is entirely regenerated by a sequence of AC to DC conversion followed by DC to AC conversion in order to create power supply without any electrical interference. Double Conversion UPSs can be used with any type of equipment as there are no transients when changing over to battery power.
