data sheet september 8, 2008 fnw500r power modul es; dc-dc converters 36 ? 75 vdc input; 28vdc output; 500w output lineage power 7 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 circui t 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 i (-) 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 current- limiting 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 overlo ad condition still exists when the module restarts, it will shut down again. this operation will continue indefinit ely, until the overcurrent condition is corrected. over voltage protection the output overvoltage protec tion consists of circuitry that monitors the voltage on the output terminals. if the voltage on the output terminals exceeds the over voltage protection threshol d, 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.

data sheet september 8, 2008 fnw500r power modul es; dc-dc converters 36 ? 75 vdc input; 28vdc output; 500w output lineage power 9 feature description (continued) 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 betw een 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 o,nom . the voltage between the vo(+) and vo(-) terminals must not exceed the mini mum output overvoltage shut- down value indicated in t he feature specifications table. this limit includes any increase in voltage due to remote-sense compensation and output voltage set- point adjustment (trim). see figure 13. if not using the remote-sense feature to regul ate the output at the point of load, then connect sense(+) to vo(+) and sense(- ) to vo(-) at the module. although the output volta ge can be increased by both the remote sense and by the trim, the maximum increase for the output voltag e 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. figure 13. effective circuit configuration for single- module remote-sense operation output voltage. over temperature protection the fnw500r module provides with non-latching over temperature protection. a te mperature sensor monitors the operating temperature of the converter. if the reference temperature exceeds a threshold of 106 c (typical) at the center of the baseplate, the converter will shut down and disable the output. when the baseplate temperature has decreased by 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 dc and 13 v dc . this supply is typically used to drive leds. to prevent internal module damage, do not connect or short this pin to any other pin on the module. power good signal the module contains a power good signal on pin 15, consisting of an open collector circuit that is referenced to the sense- pin on the secondary side of the module. the power good signal is active low, when the module is operating normally. the maximum current that can sunk at this pin, during normal operation active low, is 35 ma dc , and the maximum voltage allowed on the pin, during module abnormal operation active high, is 35v dc . during transient load changes or during overcurrent hiccup events, the sanity of the power good signal is not guaranteed.
