Optional Functions
The A-Series 7-15W DC/DC Converters offer numerous electrical/ mechani-
cal options. Per the Ordering Guide on page 2, the trailing "A" (A-Series) in
each part number pertains to the base part number. Part-number suffixes are
added after the "A," indicating the selection of standard options. The resulting
part number is a "standard product" and is available to any customer desiring
that particular combination of options. As described below, selecting certain
options will result in the installation of additional pins in certain locations.
Suffix Description
blank No VOUT Trim or On/Off Control functions added (no I/O pins
installed in the pin 3 and pin 5 positions). The pin length remains at
0.2 inches (5.08 mm).
T
Add a VOUT Trim function on pin 5. No pin 3 installed.
C
Add an On/Off Control function on pin 3 (with positive polarity).
No pin 5 installed.
CT
Add the On/Off Control function (with positive polarity) on pin 3
and add the VOUT trim function on pin 5.
N
Add an On/Off Control function on pin 3 with negative polarity. No
pin 5 installed.
NT
Add the On/Off Control function with negative polarity on pin 3
and add the VOUT trim function on pin 5.
L1
Trim the pin length to 0.110 ±0.010 inches (2.79 ±0.25mm). This
option requires a 100-piece minimum order quantity.
L2
Trim the pin length to 0.145 ±0.010 inches (3.68 ±0.25mm). This
option requires a 100-piece minimum order quantity.
-C
RoHS-6 hazardous substance compliance.
Adaptations
There are various additional configurations available on A-Series 7-15W
DC/DC's. Because designating each of them with a standard part-number
suffix would result in an unmanageable matrix of part numbers, such are
designated by C&D and assigned 5-digit "part-number suffixes. Once a
configuration has been requested by a customer and created by C&D, the
resulting product is available to any customer as a "standard" off-the-shelf
product. Consequently, the following products are offered for sale:
UWR-3.3/4250-D48AT-30690
Standard product, 48VIN, 3.3VOUT/4.25A with a VOUT Trim function added in
the pin 3 position, with adapted current limit set point to 6.5A min. and with
removed Input Overvoltage Shutdown function.
UWR-5/3000-D48ACT-30770
UWR-5/3000-D48ACT-30770-Y (RohS-5)
Standard product, 48VIN, 5VOUT/3A. On/Off Control function (positive polarity)
on pin 3, VOUT, Trim function added on pin 5. Adaptations: Trim equations are
Tyco/Lucent-compatible. Transformer isolation system has been enhanced to
meet the BASIC INSULATION requirements of UL60950/EN60950. I/O pins
are 25-mil-square Tyco/Lucent compatible. Shielded metal case is connected
to +VIN pin 1. Input Overvoltage Shutdown function has been removed.
UWR-3.3/4500-D48ANT
Standard UWR-3.3/4250-D48A, 48VIN, 3.3VOUT with slightly higher output
current (4.5A), negative on/off polarity control and a special competitive-com-
patible trim.
UWR-3.3/4500-D48ANT accepts trim adjustments to ±10% of nominal VOUT not
to exceed 15W of maximum output power. Users should carefully consider the
amount of trim added since excessive positive trim may exceed the overvolt-
age protection. Excessive negative trim may interfere with proper regulation.
UWR-3.3/4500-D48ANST Special trim version. See page 5.
* Note: Usage of consecutive "C" and "-C" designations is correct for some
models. Example: UWR-5/3000-D48AC-C
