Organization: UL
Publication Date: 28 June 1994
Status: inactive
Page Count: 156
scope:

These requirements cover portable, stationary, and fixed power units having an input rating of 600 volts or less, direct- and alternating- current, with at least one output not marked Class 2, and that are intended to be employed in ordinary locations in accordance with the

National Electrical Code, INNS/NFPA 70.

These requirements cover general purpose power supplies and power

supplies for uses such as to supply some household appliances, school laboratories, cathodic protection equipment; power supply-battery charger combinations; and industrial equipment, including inverters, divided into two classes - those rated 10 kilovolt-amperes or less and

those rated more than 10 kilovolt-amperes.

Power units with all outputs identified as Class 2 are covered under The

Standard for Class 2 Power Units, UL 1310.

These requirements cover battery chargers other than the type intended

to charge motor-starting batteries and those for charging industrial batteries which power material handling trucks, tractors, personnel carriers, and similar motive equipment. These battery chargers are covered under The Standard For Battery Chargers for Charging Engine-Starter Batteries, UL 1236, and the Standard for Industrial

Battery Chargers, UL 1564, respectively.

A battery charger for charging automotive-type batteries for other than

motor-starting purposes, such as powering a trolling motor, is investigated to the requirements in this standard and the applicable requirements for battery chargers under UL 1236, the Standard for Battery Chargers for Charging Engine-Starter Batteries, or UL 1564, the

Standard for Industrial Battery Chargers.

These requirements do not cover a power supply for a fire-protective or

burglary-protective signaling system, electrostatic-air cleaning equipment, recreational vehicles, electric discharge or neon tubing, test equipment for commercial or industrial laboratories; or an

appliance or system in which the power supply is used.

Revised 1.6 effective October 9, 2002

These requirements cover power supplies for centralized ac or dc power

systems, including dc power supplies, rectifiers, and the like, that form part of these systems.

A power supply that is intended for use with a specific type of product other than as referenced in 1.2 is investigated under the

standard for that end product.

These requirements do not cover the effect that a power supply may have

on an equipment or a system to which it is connected.

A product that contains features, characteristics, components,

materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
