page 5 of 17 input transient and reverse polarity protection a dr resistor and a symmetrical input flter form an eective protection against input transients, which typically occur in many installations, but especially in battery-driven mobile applications. if the input voltage has the wrong polarity, the incorporated reverse diode will cause the external input circuit breaker or fuse to trip. with option m or f (incorporated fuse), an active reverse-polarity protection circuit prevents from any damage. input under- / overvoltage lockout if the input voltage is out of range, an internally generated signal dis ables the converter to avoid any damage. efciency see fg 60 70 80 90 0.4 0.8 p o / p o no m 0 jm216 100 [%] 0.6 0.2 11 0rcm500-24dmq v i = 137 v v i = 77 v 60 70 80 90 0.4 0.8 p o / p o nom 0 jm215 100 [%] 0.6 0.2 11 0rcm1000-24dmq v i = 110 v v i = 137 v v i = 77 v fig. 2a efciency versus v i and p o (110rcm500-24dmq) fig. 2b efciency versus v i and p o (110rcm1000-24dmq) tech.support@psbel.com belfuse.com/power-solutions bcd.00803 rev ac, 10-may-2018 rcm series 500 / 1000 w dc-dc converters ? 2018 bel power solutions & protection

page 8 of 17 thermal considerations and protection a temperature protection is incorporated in the primary and secondary control logic each. it generates an internal inhibit signal, which disables the converter in case of over tem per a ture. the converter automatically recovers, when the temper a ture drops below the limit; see fg. 6. the relationship be tween t a and t c depends heavily upon the conditions of operation and the integration into a system. caution: the installer must ensure that under all operating con ditions t c remains within the limits stated in table 7. 0 200 400 600 800 50 60 70 80 90 100 p o [w] t a [c] 1000 rcm1000 jm252 t c max convection cooling rcm500 40 with heatsink (dotted lines) fig. 6 7sfdorssrzhghdqhvvhpshdh hfdoprqqsrvrqihhfrqhfrqfrroq led indicator each converter exhibits a green led out ok, signaling that the output voltage is inside the specifed range. tech.support@psbel.com belfuse.com/power-solutions bcd.00803 rev ac, 10-may-2018 rcm series 500 / 1000 w dc-dc converters ? 2018 bel power solutions & protection
