Advances in power semiconductor technology, particularly the introduction of the Insulated Gate Bipolar Transistor (IGBT),transformer less topology has largely taken over from traditional transformer-based designs because of the many advantages it offers. The transformer less design of DS series delivers improved efficiency from a considerably smaller and lighter form factor, while several further benefits also apply DS series UPS systems also present a higher input power factor than their transformer-based equivalents.
The main representation of power quality is the harmonic distortion, which represents the deviation between the ideal sinusoidal waveform the network voltage or the load current should have, and what really it is. In UPS systems, lower THD implies lower peak currents, less heating, lower electromagnetic emissions, and less core loss in motors
DS Series’ advanced rectifier technology guarantees the supply of current with an exceptionally low rate of harmonic distortion: THDI < 3 %.
Energy efficiency for uninterruptible power supply (UPS) equipment is so important because they can influence UPS energy efficiency and can directly impact energy costs. The lower the efficiency of the UPS, the more heat that is generated and the more cooling that is required in the room, driving up capital costs and the ongoing operational expenses of the cooling system. To mitigate the losses, DS series energy-efficient UPS systems employ a power management system that precisely controls every pulse of the switching cycle, optimizing the inverter's switching for specific load types and load levels. The resulting switching patterns suffer the least possible losses and surpass the efficiency of older-style systems with fixed switching patterns
DS series temperature compensated charging helps to prolong battery life by dynamically adjusting the voltage depending on the ambient temperature. It ensures maximum UPS battery charge in colder conditions. While it reduces the risk of overcharging in warmer operating conditions. Special circuitry fitted to the UPS dynamically adjusts the recharge voltage depending on changes to the ambient temperature. In essence, the higher the temperature, the lower the recharge voltage. Reducing the charge voltage at higher temperatures optimizes the chemical reaction. Without this compensation, the batteries may overcharge.
With SNMP interface, facilities like remote management and monitoring and auto are present. Also, environment monitoring systems can be interfaced to receive real time alerts about power failure ,water leakage etc. Other connectivity options such as USB, RS 485, RS 232 available with Taurus
