4 State-of-art DSP technology, with operating speed 12 times quicker than traditional micro-processor.
4 Fully digital electrical circuitry (no analog circuitry) to ensure high reliability and immunity to interference.
4 Main/auxiliary compatible controlled circuitry to enhance reliability.
4 Adopt D-C suppression circuitry, minimizes fluctuation after parallel configuration to less than 0.5%.
4 Adopt smart charger that provides automatic compensation of the battery voltage in relation to temperature and floating data balance mechanism for optimal charge condition. Regular self test can help detect battery failure at early stage. The battery discharge time can also be set.

4 adopt DSP digital technology
4 large LCD display
4 user-friendly smart menu
4 internal self diagnosis software is installed

4 broader power input range
4 with lightening suppressor
4 with isolated transformer design
4 self equipped high capacity and long life charger
4 internal harmonic free and loss compensation circuit design, which  can reduce the EMI and RFI disturbance.
4 Standardized anti-reverse flow PBI device, which prevent the      equipment from short circuit and reverse flow of current into the  power network.
4 Standardized output isolation transformer (DSL series
     with bypass separation). This ensures UPS output power and no ground interference. This best fits military and industrial level applications.
