DSD31 / DSD33
Features
* DSD31 / DSD33
* True galvanic isolation design ensures that such serious AC mains problems as noise, lightning
effects, leakage current do not reach your systems.
* Protection from the accidental disconnection of the neutral wire ensures the safety of the UPS
and the stability of the power supply.
* Protection from incorrect operation ensures that violating the operation procedures will not
lead to UPS or connected equipment damage.
* The use of up-to-date DSP, IGBT and switching components ensures the high reliability and
efficiency of the UPS.
* Multi-CPU design increases the system reliability.
* Plug-and-play design and easy access to boards ensures the fastest and easiest UPS
maintenance.
* Individual inverter for each phase ensures stable work under completely unbalanced load.
* Intelligent charger with temperature compensation feature ensures the longest possible battery
life. The adjustable level of charging current allows the UPS to work with large battery banks for
long backup time.
* Intelligent battery test logics eliminate the possibility of power supply interruption during battery
test in case of batteries being bad. Provides the detection of battery electrolyte leakage and
improper battery grounding.
* Intelligent fan speed control increases the fan life expectancy and reduces the audible noise.
* Advanced heat abstraction design by physical separation of the power and control circuitry
ensures the smooth operation of the UPS under most harsh conditions.
* Cold start function makes it possible to start the UPS even when AC mains are not providing the
power.
* 12-pulse rectifier ensures reduced harmonics for UPS with capacities of 80KVA and higher.
* Input harmonic filter reduces the Total Harmonic Distortion (T.H.D.) of the UPS.
* Parallel operation makes it possible to upgrade the UPS to a larger capacity.
