UL Online Certifications Directory

The devices covered under this category are incomplete in certain constructional features or restricted in performance capabilities and are intended for use as components of complete equipment submitted for investigation rather than for direct separate installation in the field. THE FINAL ACCEPTANCE OF THE COMPONENT IS DEPENDENT UPON ITS INSTALLATION AND USE IN COMPLETE EQUIPMENT SUBMITTED TO UNDERWRITERS LABORATORIES INC.

USE

This category covers component power supplies intended for use in/with information technology and including electrical business equipment. End-use products that employ these types of power supplies are covered under Information Technology Equipment Including Electrical Business Equipment Certified for Canada (NWGQ7).

CONDITIONS OF ACCEPTABILITY

Consideration is to be given to the Conditions of Acceptability specified in the individual Recognitions and/or Reports when these components are employed in the end-use equipment.

REBUILT PRODUCTS

This category also covers Recognized Component power supplies that are rebuilt by the original manufacturer or another party having the necessary facilities, technical knowledge and manufacturing skills. Rebuilt power supplies are rebuilt to the extent necessary by disassembly and reassembly using new or reconditioned parts. Rebuilt power supplies are subject to the same requirements as new power supplies.

CODES

The following summarizes and defines codes shown in the individual Recognitions in addition to those indicated under Power Supplies Certified for Canada (QQAQ8).

Supply Category (SC) — Code identifies the type of supply to which the component is intended to be connected.

Maximum Voltage (Max V) — The maximum output voltage under any resistive loading condition is indicated in volts peak.

Maximum Amperes (Max A) — The maximum output current under any resistive loading condition is indicated in amperes rms.

Maximum Volt (Max VA) — The maximum output volt-amperes under any resistive loading condition is indicated in volt-amperes rms.

Output Category (OC) — Each output is identified to indicate the type of output.

Spacings (SP) — The standard used in judging spacings (or creepage and clearance distances) is indicated by the standard number.

External Protection (EP) — Tests on the component were conducted with the primary protected by external overcurrent protection.

Field Connections (FC) — Code indicates whether supply and output connections have been investigated for field connections.

Grounding Connection (GC) — Units with functional grounding connections (no safety grounding connection) are intended to have dead metal parts bonded to the end-product grounding means.

REQUIREMENTS

The basic standard currently used to investigate products in this category is CAN/CSA-C22.2 No. 60950-1, "Information Technology Equipment - Safety - Part 1: General Requirements," or CAN/CSA-C22.2 No. 60950-21, "Information Technology Equipment - Safety - Part 21: Remote Power Feeding."

UL MARKING

Components Recognized under UL's Component Recognition Program are identified by markings consisting of the Recognized company's identification and catalog, model, or other product designation. In addition, components produced under the UL Component Recognition Program will also bear the Recognized Component Mark for Canada .

For rebuilt products the word "Rebuilt,""Remanufactured" or "Reconditioned" precedes the product name.

The Listing or Classification Mark of Underwriters Laboratories Inc. is not authorized for use on, or in connection with, Recognized Components. Only those components that actually bear the "Marking" should be considered as being covered under the Component Recognition Program.
