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.

-Y RoHS-5 hazardous substance compliance with lead exception.

(Applicable only to UWR-12/1250-D48L1-Y as of this date.)

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 DATEL and assigned 5-digit "part-number suffixes. Once a

configuration has been requested by a customer and created by DATEL, 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.

RoHS-5 compliance refers to the exclusion of the six hazardous substances

in the RoHS specification with the excepion of lead. C&D Technologies'

RoHS-5 products use all the conforming RoHS materials, however our

solders are Sn63/Pb37.

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.
