2 KDC Series II DC Power Supplies
1.2 KDC Controllers Series I versus Series II
The original controller version used in the KDC Series has been updated and is now referred to as
KDC II or Series II. The difference is in the way parallel operation of two or more units is
accomplished. KDC units with KDC II controllers have a top-level assembly revision of E as
indicated on the model serial tag. Revisions D and older have an original KDC controller.
Series II KDC models use either controller assembly 5005-721-1 or 5005-724-1. The 5005-724-1
replaced the 5005-721-1 controller as of August 2006 product shipments and is back ward
compatible with the 5005-721-1 controller.
Note: It is not possible to parallel a KDC Series I with a KDC Series II. Thus only
KDC units having the same generation controller can used in master /
auxiliary configuration.
This user manual is intended for use with KDC Units having a revision letter of E or higher. If the
unit you are using has a revision letter of D or lower, use user manual P/N 5005-960 instead. Both
user manuals are distributed on the same CD-ROM or are available for download from the
Argantix web site (
www.argantix.com ).
1.3 Bench Top use
The KDC Series DC Supply may be used as a bench top unit provided adequate provisions are
made to protect the end-user from touching the output terminals on higher voltage models. To this
end, output covers are provided on all KDC units. These covers must be installed during use and
may only be removed when the unit is not in use and disconnected from AC mains.
Adequate air flow must be maintained at all times so care should be taken not to block the top and
side air intakes or the rear air exhaust. Leave at least 4" of clearance at the back of the unit to
allow proper airflow.
1.4 Equipment Rack use
The KDC Series uses a 19" cabinet with rack ears and can be installed in a standard equipment
rack. Due to the weight of the unit however, it must be properly supported by either a shelf or L
brackets on both sides. The rack ears are not designed to support the full weight of the KDC unit
when installed in a cabinet but only to prevent it from sliding out.
Contact AMETEK Programmable Power customer support ( sales@programmablepower.com ) for
information on rack mount kits for specific cabinets depths. See also paragraph 2.11 for available
rack mount brackets.
Proper airflow must be maintained in the instrument cabinet and the rear of the cabinet should not
be closed off by a door but rather a perforated screen allowing adequate airflow. It is also
important to leave enough clearance above each unit as some of the air intake is on the top
cover.
Note: It is recommended to leave a 1.75" (1 U) space above each KDC unit.
A louvered cover plate to allow some air intake from the front of the cabinet may be used to cover
this space. When planning total cabinet space, allow for 4U per DC supply.
If space is at a premium, units may be mounted with no space. Maximum operating temperature
may have to be derated to 35° under these conditions.
