PRODUCT COVERED:
*USR, CNR Recognized Component - Power Supply, Model No. 4FD6383-0LA021A, 4FD6383-0LA03-1A
GENERAL CHARACTER AND USE:
This product is a switching mode power supply mounted in a waterproof
enclosure which was not evaluated for “waterproof” capability. The unit is
provided with input and output terminals for connection to the end-use
equipment. The power supply has been investigated to UL 1012, Standard for
Power Supplies, Sixth Edition. Models 4FD63-0LA02-1A and 4FD6383-0LA03 are
identical except that model 4FD6363-0LA02-1A is provided with an external
waterproof attachment plug receptacle. All models provided with an access
window for field terminal wiring in the end-use product.
*CNR - The basic standard used to investigate products in this category is
CAN/CSA-C22.2 No. 107.1
*Note:
USR = United States Standards, Recognized
CNR = Canadian National Standards, Recognized

ENGINEERING CONSIDERATIONS (NOT FOR UL REPRESENTATIVE USE):
The power supplies are intended for use in letter sorter machines. The
number of contactors activated at the same time varies continuously. The
indicated secondary load is considered as worst case (all contactors powered).
For use only in or with equipment where the acceptability of the
combination is determined by Underwriters Laboratories Inc.

Conditions of Acceptability - When installed in the end-use equipment,
the following are among the considerations to be made:
1.
The power supply shall be installed in compliance with the
marking, enclosure, mounting, spacing, casualty and segregation requirements
of the ultimate application.
2.
Consideration should be given to measuring the temperatures on
power electronic components and transformer/choke windings when the power
supply is installed in the end-use equipment. The transformers/ chokes comply
with Class 130°C limits.
3.
This power supply has been judged on the basis of the required
spacings in the Fourth Edition of the Standard for Power Supplies, Par. 26 and
Tables 26.2.
4.
All Normal and Abnormal Tests were conducted using a 230 V, 1
phase, 50 Hz supply source and a Listed or R/C (JDYX2) 4A time delay fuse,
provided with the unit.
5.
The need for and suitability of the strain relief mechanisms shall
be determined. The R/C (QCRV2) bushings, Type ST11, made by Lapp UI GmbH were
not evaluated for strain relief.
6.
These power supplies are intended for use only in a controlled
environment. The enclosures provided shall be evaluated for such use in the
end application, if necessary.
7.
The units nameplate ratings should be evaluated for accuracy (if
relevant) in the end use application, based on secondary loading.
