Overtemperature Protection The converter is protected against possible overheating by means of an internal temperature monitoring circuit. It shuts down the converter above the internal temperature limit and attempts to automatically restart. This feature prevents excessive internal temperature building up which could occur under heavy overload conditions. Short Circuit Behavior The current limit characteristic shuts down the converter whenever a short circuit is applied to an output. It acts self- protecting and automatically recovers after removal of the overload condition (hiccup mode). Thermal Considerations If a converter, mounted on a PCB, is located in free, quasi- stationary air (convection cooling) at the indicated maximum ambient temperature TA max (see table Temperature specifi- cations) and is operated at its nominal input voltage and output power, the case temperature TC (TC Z with option Z) measured at the measuring point of case temperature (see Mechanical Data) will approach the indicated value TC max after the warm- up phase. However, the relationship between TA and TC depends heavily on the conditions of operation and integration into a system. The thermal conditions are influenced by input voltage, output current, airflow, temperature of surrounding components and the surfaces and properties of the printed circuit board. TA max is therefore only an indicative value, and under practical operating conditions, the ambient temperature TA may be higher or lower than this value. Caution: The case temperature TC (or TC Z) measured at the measuring point of case temperature (see Mechanical Data) may under no circumstances exceed the specified maximum value. The installer must ensure that under all operating conditions TC (or TC Z) remains within the limits stated in the table Temperature specifications. The converters provide the specified output power with free air convection cooling. In the upper temperature range the output power derating below should be observed. Series and Parallel Connection The outputs of one or several double-output power trains may be connected in series respecting the current limitation. Both outputs of the same power train can always be connected in parallel in will behave like a single output. Several outputs of the same converter with equal output voltage (e.g. 5 V / 5 V) can be connected in parallel and will share their output currents almost equally. If outputs of the same converter are being parallel and series- connected, it is recommended that outputs from the same power trains are parallel-connected first. This applies for instance, if 24 V shall be generated by a converter with four 12 V outputs; see fig. 7. Fig. 6 Overload switch off (hiccup mode), typical values. Note: Parallel operation of several converters may cause start- up problems. This becomes noticable in applications, where one converter is not able to deliver allone the full resistive and capacitive load current, as it is required in true redundant systems. 70 100 V o [%] t 05041b 0.3 s overload short-circuit condition switch-off 0 1.0 0.8 0.6 0.4 0 0.2 20 40 60 80 100 °C P o /Po max 11047-X35a T A 0.5 m/s = 100 LFM natural cooling PWM 4 8 1 Vi+ SD PUL 5 Trim 6 W 7 Ref 2 Vi– 16 15 17 18 13 14 12 11 Vo4– Vo1+ Vo1– Vo4+ Vo2+ Vo2– Vo3+ Vo3– JM138 3 n.c. 19 n.c. –24V +24V IMX35D12D12-9 Fig. 7 Generating 24 V with an IMX35D12D12-9 |
