This is the second edition of CSA C813.1, Performance test method for uninterruptible power supplies. It supersedes the previous edition published in 2001.
The purpose of this Standard is to specify the requirements, definitions, and testing method for measuring the electrical characteristics of uninterruptible power supplies. It is written in SI (metric) units.
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
This Standard applies to uninterruptible power supplies (UPS). The primary function of the UPS covered by this Standard is to ensure continuity of an alternating power source. The uninterruptible power supplies can also serve to improve the quality of the power source by keeping it within specified characteristics.
This Standard is applicable to movable, stationary, fixed, and built-in UPS for distribution systems up to and including 600 V ac.
This Standard does not apply to the following products:
a) products that are internal to a computer or another end-use load (e.g., battery supplemented internal power supplies or battery backup for modems, security systems, etc.);
b) utility UPSs designed for use as part of electrical transmission and distribution systems (e.g., electrical substation or neighborhood-level UPSs);
c) cable TV (CATV) UPSs designed to power the cable signal distribution system outside plant equipment and connected directly or indirectly to the cable itself. The cable may be coaxial cable (metallic wire), fiber-optic, or wireless (e.g., Wi-Fi);
d) UPSs designed to comply with specific safety-related applications, such as emergency lighting, operations or egress, or medical diagnostic equipment;
e) UPSs designed for mobile, ship board, marine, or airborne applications; and
f) Dc-output UPSs/rectifiers.
In this Standard, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the standard.
