IEC 62040-5-3:2016 establishes the performance and test requirements applied to movable, stationary and fixed electronic DC uninterruptible power systems (DC UPS) that
– are supplied from an AC voltage source not exceeding 1 000 V,
– deliver a DC output voltage not exceeding 1 500 V,
– incorporate an energy storage device, and
– have a primary function to ensure continuity of DC power to loads. This document specifies performance and test requirements of a complete DC UPS and not of individual DC UPS functional units.
