Description
The KNW (Sixteenth-brick) series power modules are isolated dc-dc converters that operate over a wide input
voltage range of 36 to 75Vdc and provide a single precisely regulated output. The output is fully isolated from the
input, allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency,
typical efficiency of 91% for 3.3V/20A. These open frame modules are available either in surface-mount (-SR) or in
through-hole (TH) form.

Design Considerations
Input Filtering
The power module should be connected to a low
ac-impedance source. Highly inductive source
impedance can affect the stability of the power
module. For the test configuration in Figure 13, a
33μF electrolytic capacitor (ESR<0.7at 100kHz),
mounted close to the power module helps ensure the
stability of the unit. Consult the factory for further
application guidelines.
Safety Considerations
For safety-agency approval of the system in which the
power module is used, the power module must be
installed in compliance with the spacing and
separation requirements of the end-use safety agency
standard, i.e UL60950-1, CSA C22.2 No.60950-1,
and VDE0805-1(IEC60950-1).
If the input source is non-SELV (ELV or a hazardous
voltage greater than 60 Vdc and less than or equal to
75Vdc), for the module’s output to be considered as
meeting the requirements for safety extra-low voltage
(SELV), all of the following must be true:
The input source is to be provided with reinforced
insulation from any other hazardous voltages,
including the ac mains.
One VIN pin and one VOUT pin are to be
grounded, or both the input and output pins are
to be kept floating.
The input pins of the module are not operator
accessible.
Another SELV reliability test is conducted on the
whole system (combination of supply source and
subject module), as required by the safety
agencies, to verify that under a single fault,
hazardous voltages do not appear at the
module’s output.
Note: Do not ground either of the input pins of the
module without grounding one of the output
pins. This may allow a non-SELV voltage to
appear between the output pins and ground.
The power module has extra-low voltage (ELV)
outputs when all inputs are ELV.
All flammable materials used in the manufacturing of
these modules are rated 94V-0, or tested to the
UL60950 A.2 for reduced thickness.
For input voltages exceeding –60 Vdc but less than or
equal to –75 Vdc, these converters have been
evaluated to the applicable requirements of BASIC
INSULATION between secondary DC MAINS
DISTRIBUTION input (classified as TNV-2 in Europe)
and unearthed SELV outputs.
The input to these units is to be provided with a
maximum 5 A time-delay fuse in the ungrounded lead.
