Feature Descriptions
The voltage between the Vo(+) and Vo(–) terminals
must not exceed the minimum output overvoltage
protection value shown in the Feature Specifications
table. This limit includes any increase in voltage due
to remote-sense compensation and output voltage
set-point adjustment trim.
Although the output voltage can be increased by both
the remote sense and by the trim, the maximum
increase for the output voltage is not the sum of both.
The maximum increase is the larger of either the
remote sense or the trim. The amount of power
delivered by the module is defined as the voltage at
the output terminals multiplied by the output current.
When using remote sense and trim, the output
voltage of the module can be increased, which at the
same output current would increase the power output
of the module. Care should be taken to ensure that
the maximum output power of the module remains at
or below the maximum rated power (Maximum rated
power = Vo,set x Io,max).
Thermal Considerations
The power modules operate in a variety of thermal
environments; however, sufficient cooling should be
provided to help ensure reliable operation.
Considerations include ambient temperature, airflow,
module power dissipation, and the need for increased
reliability. A reduction in the operating temperature of
the module will result in an increase in reliability. The
thermal data presented here is based on physical
measurements taken in a wind tunnel.
The thermal reference point, T
specifications is shown in Figure 43. For reliable
operation this temperature should not exceed 120

KW010/015/020/025 Series Power Modules:
EMC Considerations
The KW series modules are designed to meet the
conducted emission limits of EN55022 class A with no
filter at the input of the module. The module shall
also meet limits of EN55022 Class B with a
recommended single stage filter. Please contact your
Lineage Power Sales Representitive for further
information.
