NOTES
1. Tested by minimum input and constant resistive load.
2. Trimming allows the user to increase or decrease the output voltage set point of the module. This is accomplished by connecting an external
resistor between the Trim pin and either +Vout pin or –Vout pn.
3. The ON/OFF control pin is referenced to –Vin. To order Negative Logic Remote ON/OFF add the suffix “R” to the model number.
4. Heatsink is optional and P/N: 7G-0047C-F. See “Model Number Setup” on page 4 for more information.
5. EN55022
1. To meet Class A the module needs no external components.
2. To meet Class B please refer to the filter suggestion on page 4.
6. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. The suggested filter capacitor is Nippon chemi-
con KY series, 220µF/100V.
CAUTION: This power module is not internally fused. An input line fuse must always be used.
*Due to advances in technology, specifications subject to change without notice.

FUSE CONSIDERATION
This power module is not internally fused. An input line fuse must always be used.
This encapsulated power module can be used in a variety of applications, ranging from simple stand-alone operation to an integrated
part of sophisticated power architecture.
To maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input
line fuse.

The table based on the information provided in this data sheet on inrush energy and maximum DC input current at low Vin.
THERMAL CONSIDERATION
This power module operates in a variety of thermal environments, however, sufficient cooling should be provided to help ensure reliable
operation of the unit. Heat is removed by conduction, convection, and radiation to the surrounding environment.
Proper cooling can be verified by measuring the point in the figure below. The temperature at this location should not exceed 105ºC.
When operating, adequate cooling must be provided to maintain the test point temperature at or below 105ºC.
Although the maximum point temperature of the power modules is 105ºC, you can limit this temperature to a lower value for extremely
high reliability.
■Thermal test condition with vertical direction by natural convection (20LFM).

OUTPUT VOLTAGE ADJUSTMENT
Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of the module. This is
accomplished by connecting an external resistor between the Trim pin and either the +Output or -Output pins.
With an external resistor between the Trim and -Output pin, the output voltage set point increases.
With an external resistor between the Trim and +Output pin, the output voltage set point decreases.
The external Trim resistor needs to be at least 1/16W of rated power.
