IEC EN 62040-5-3 Uninterruptible Power Systems - Test for DC Output UPS

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62040-5-3 testing. This standard specifies the performance and testing requirements of a complete DC UPS, not stand-alone DC UPS functional units.

The individual DC UPS functional units are covered in the IEC publications referenced in the hitherto valid bibliography without conflicting with this document.

DC UPSs have been developed in a wide power range from less than a hundred watts to megawatts to meet availability and power quality requirements for various loads.

This document also contains DC UPS performance and test requirements for breakers, isolating switches, and disconnect switches, if any, integrated into the DC UPS. These components interact with other functional units of the DC UPS to maintain load power continuity.

This document does not cover:

• Conventional AC input distribution boards and their associated switches,
• Conventional DC distribution boards and their associated switches,
• Conventional AC UPSs under IEC 62040-3,
• Low-voltage DC power supply devices within the scope of a particular product standard, such as IEC 61204 and those covered by a particular product standard, such as ITU communication standards and
• Systems where the output voltage is derived from a rotating machine.
