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 being an integrated part of complex power architecture. To preserve maximum flexibility, internal fusing is not included. Always use an input line fuse, to achieve maximum safety and system protection. The safety agencies require a time-delay or fast-acting fuse with a maximum rating of 30 A (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.

Test Configurations
Note: Measure the input reflected-ripple current with a simulated source inductance (LTEST) of 12 µH. Capacitor CS offsets possible battery impedance. Measure the current, as shown above.
Figure 7. Input Reflected Ripple Current Test Setup.
Note: Use a Cout (470 µF Low ESR aluminum or tantalum capacitor typical), a 0.1 µF ceramic capacitor and a 10 µF ceramic capacitor, and Scope measurement should be made using a BNC socket. Position the load between 51 mm and 76 mm (2 in. and 3 in.) from the module.
Figure 8. Output Ripple and Noise Test Setup.
Note: All measurements are taken at the module terminals. When socketing, place Kelvin connections at module terminals to avoid measurement errors due to socket contact resistance.

Design Considerations
Input Source Impedance
The power module should be connected to a low ac-impedance source. A highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 7, a 470μF Low ESR aluminum capacitor, C power module helps ensure the stability of the unit. Consult the factory for further application guidelines
, mounted close to the
IN
Output Capacitance
The FNW500R power module requires a minimum output capacitance of 470µF Low ESR aluminum capacitor, C range of load and line conditions, see Figure 8. If the ambient temperature is under -20C, it is required to use at least 3 pcs of minimum capacitors in parallel. In general, the process of determining the acceptable values of output capacitance and ESR is complex and is load-dependant.

out
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. 60950-1-03, EN60950-1 and VDE 0805:2001-12.
For end products connected to –48V dc, or –60Vdc nominal DC MAINS (i.e. central office dc battery plant), no further fault testing is required. *Note: -60V dc nominal battery plants are not available in the U.S. or Canada.
For all input voltages, other than DC MAINS, where the input voltage is less than 60V dc, if the input meets all of the requirements for SELV, then:
The output may be considered SELV. Output
voltages will remain within SELV limits even with internally-generated non-SELV voltages. Single component failure and fault tests were performed in the power converters.
One pole of the input and one pole of the output are to be grounded, or both circuits are to be kept floating, to maintain the output voltage to ground voltage within ELV or SELV limits. However, SELV will not be maintained if V grounded simultaneously.

36 – 75 Vdc Input; 28Vdc Output; 500W Output
Safety Considerations (continued)
For all input sources, other than DC MAINS, where the input voltage is between 60 and 75V dc (Classified as TNV-2 in Europe), the following must be meet, if the converter’s output is to be evaluated for SELV:
The input source is to be provided with reinforced
insulation from any hazardous voltage, including the ac mains.
One Vi pin and one Vo pin are to be reliably
earthed, or both the input and output pins are to be kept floating.
Another SELV reliability test is conducted on the
whole system, as required by the safety agencies, on the combination of supply source and the subject module to verify that under a single fault, hazardous voltages do not appear at the module’s output.
All flammable materials used in the manufacturing of these modules are rated 94V-0, or tested to the UL60950 A.2 for reduced thickness.
The input to these units is to be provided with a maximum 30 A fast-acting or time-delay fuse in the unearthed lead.
Feature Description
Remote On/Off
Remote ON/OFF control is available as standard and has positive logic remote On/Off mode only. The converter will be active as long as a current Ion/off (1 to 5mA) is flowing into the ON/OFF+ (pin 4) and from the ON/OFF- (pin 3), and inactive when no current is flowing. Remote control pins are isolated up to 1.5 kV. The voltage to drive this current can be derived from the input voltage, the output voltage, or an external supply with an appropriate current limit resistor. The maximum forward current allowable without damage is 5 mA, and the maximum reverse current is 10mA. A typical remote ON/OFF circuit is shown as Figure 10. The current limit resistor (R1) is connected from Vin (+) pin to ON/OFF + pin, an open collector or an equivalent switch can be connected between ON/OFF - and V pins to control ON/OFF operation. A 0 Ohm resistor (R2) can be used if no open collector or switch used. For 48Vin, an appropriate R1 value is recommended to be 30Kohm (0.5W).

Figure 10. Circuit configuration for using Remote On/Off Implementation.
Overcurrent Protection
To provide protection in a fault output overload condition, the module is equipped with internal current­limiting circuitry and can endure current limit for few milli-seconds. A latching shutdown option is standard. If overcurrent persists for few milli-seconds, the module will shut down and remain off until the module is reset by either cycling the input power or by toggling the on/off pin for one second.
An auto-restart option (4) is also available in a case where an auto recovery is required. If overcurrent persists for few milli-seconds, the module will shut down and auto restart until the fault condition is corrected. If the output overload condition still exists when the module restarts, it will shut down again. This operation will continue indefinitely, until the overcurrent condition is corrected.
Over Voltage Protection
The output overvoltage protection consists of circuitry that monitors the voltage on the output terminals. If the voltage on the output terminals exceeds the over voltage protection threshold, then the module will shutdown and latch off. The overvoltage latch is reset by either cycling the input power for one second or by toggling the on/off signal for one second. The protection mechanism is such that the unit can continue in this condition until the fault is cleared.
An auto-restart option (4) is also available in a case where an auto recovery is required.
Output Voltage Programming
Trimming allows the user to increase or decrease the output voltage set point of a module. Trimming down is accomplished by connecting an external resistor between the TRIM pin and the SENSE(-) pin. Trimming up is accomplished by connecting external resistor between the SENSE(+) pin and Vo(+) pin. The trim resistor should be positioned close to the module.
Be sure to use a zero resistor or short SENSE(+) and Vo(+) pins when the trim up function is not used.
If not using the trim down feature, leave the TRIM pin open.

The voltage between the Vo(+) and Vo(-) terminals must not exceed the minimum output overvoltage shut­down value indicated in the Feature Specifications table. This limit includes any increase in voltage due to remote- sense compensation and output voltage set­point adjustment (trim). See Figure 13.
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 the same output current would increase the power output of the module.

Remote sense
Remote sense minimizes the effects of distribution losses by regulating the voltage at the remote-sense connections (see Figure 13). For No Trim or Trim down application, the voltage between the remote-sense pins and the output terminals must not exceed the output voltage sense range given in the Feature Specifications table i.e.:
[Vo(+) – Vo(-)] – [SENSE(+) – SENSE(-)] 2% of V
.

The voltage between the Vo(+) and Vo(-) terminals must not exceed the minimum output overvoltage shut­down value indicated in the Feature Specifications table. This limit includes any increase in voltage due to remote-sense compensation and output voltage set­point adjustment (trim). See Figure 13. If not using the remote-sense feature to regulate the output at the point of load, then connect SENSE(+) to Vo(+) and SENSE(­) to Vo(-) at the module.
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.
approximately 20 ºC the converter will automatically restart.
The module can be restarted by cycling the dc input power for at least one second or by toggling the remote on/off signal for at least one second.
Auxiliary Power Output
The module has an auxiliary power output, available on pin 16, referenced to the Sense- pin. The output is derived from the internal secondary bias supply and is capable of delivering up to 15 mA, with a voltage range that varies between 9V typically used to drive LEDs. To prevent internal module damage, do not connect or short this pin to any other pin on the module.

The FNW500R module provides with non-latching over temperature protection. A temperature sensor monitors the operating temperature of the converter.

Thermal Considerations
The power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat-dissipating components inside the unit are thermally coupled to the case. Heat is removed by conduction, convection, and radiation to the surrounding environment. Proper cooling can be verified by measuring the case temperature. Peak temperature (T
) occurs at the position indicated in
C
Figure 14.
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.
For reliable operation this temperature should not exceed 100ºC.

The output power of the module should not exceed the rated power for the module as listed in the ordering Information table.
Although the maximum T modules is 100°C, you can limit this temperature to a lower value for extremely high reliability.
Thermal Derating
The curve in Figure 15 depicts the temperature/output power derating curve for conduction cooling type applications. These applications typically will provide a low thermal impedance cooling interface that is attached to the top surface of the module and is maintained at or below the T air surrounding the module is still and is held below 72°C.

Layout Considerations
The FNW500R power module series are aluminum base board packaged style, as such; component clearance between the bottom of the power module and the mounting (Host) board is limited. Avoid placing copper areas on the outer layer directly underneath the power module.
Post Solder Cleaning and Drying Considerations
Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly. For guidance on appropriate soldering, cleaning and drying procedures,
