DSM is a high frequency, on-line double-conversion uninterruptible power supply. 0.9 output PF makes better available for load. In the same time, 6 system parallel is available, which meets the requirements of users’ demand. DSM design and high control technology provides better protection and higher reliability on load. The UPS has been designed to protect critical information and telecommunications systems, networks, services and processes whose operation could be disrupted by poor power quality and/or breaks in their mains power supply.
1.Zero Impact Source
Low input current distortion - less than 3%, high input power factor 0.99;
Delayed start-up protects its power supply sources (mains or generator) from any harmonics and reactive power generated by the loads it is powering.
2.Battery Care System
Two voltage level recharge meeting the IU characteristic;
Temperature compensation: to avoid excessive voltage being applied to the batteries in a high ambient
Extensive back-up time options using battery extension cabinets
Battery test: to detect performance degradation and predict battery failure.
