Description
The CPKW002A0C1 power module is an isolated dc-dc converter that operates over a wide input voltage range of
36 to 75 Vdc and provides a single precisely regulated output. This module is a low cost, smaller size alternative to
the existing QW030C1. The output is fully isolated from the input, allowing versatile polarity configurations and
grounding connections. The module exhibit high efficiency, typical 90% for 15V at 2A. Built-in filtering for both input
and output minimizes the need for external filtering. These open frame modules are available in through-hole (TH)
form. Standard features include Remote On/Off, output voltage adjust, overvoltage, overcurrent and
overtemperature protection.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in
excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect the device reliability.

CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power module can be used in a wide variety of applications, ranging from simple standalone operation to an
integrated part of sophisticated power architectures. To preserve maximum flexibility, internal fusing is not included,
however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies
require a fast-acting fuse with a maximum rating of 3A (see Safety Considerations section). Based on the information
provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating
can be used. Refer to the fuse manufacturer’s data sheet for further information.
