IGBT RECTIFIER DSP CONTROL The Tescom DS Power UPS uses the latest DSP technology, which can be programmed to suit a wide variety of electrical environments without compromising its performance. With DS Power, efficiency, reliability and functionality have been raised to levels not reached with old analogue technology. This technology not only significantly increases MTBF, but also, with the DSP's ability to process signals accurately at very high speed, enables all UPS subsystems to be controlled with greatly increased precision.
