➀ Please refer to the part number structure for additional ordering information and options.
➁ All specifi cations are typical at nominal line voltage and full load, +25°C unless otherwise noted. See
detailed specifi cations. Output capacitors are 1 µF || 10 µF with a 22µF input capacitor. These caps are
necessary for our test equipment and may not be needed for your application.

PART NUMBER STRUCTURE
UWQ Pin 9 Baseplate Connection
The UWQ module has an additional pin 9 on special order that connects to the baseplate but is
electrically isolated from the rest of the converter. Please refer to the mechanical drawings.
Pin 9 offers a positive method of controlling the electrical potential of the baseplate, indepen-
dent of the converter.
The baseplate may be ordered by adding a “B” to the model number tree and pin 9 will be pre-
installed by adding a “9.” The two options are separate. Please refer to the Ordering Guide. Do
not order pin 9 without the baseplate. Note that “pin 9” converters may be on limited forecast,
requiring minimum order quantities and scheduled deliveries.
