LM2320-9

The M series of DC-DC (AC-DC) converters represents a broad and flexible range of power supplies for use in advanced industrial electronic systems. Features include high efficiency, reliability, low output voltage noise and excellent dynamic response to load/line changes due to individual regulation of each output.The converter inputs are protected against surges and transients occuring at the source lines. An input over- and undervoltage lock-out circuitry disables the outputs if the input voltage is outside the specified range. Certain types include an inrush current limitation preventing circuit breakers and fuses from being damaged at switch-on.All outputs are open- and short-circuit proof and are protected against overvoltages by means of built-in suppressor diodes. The outputs can be inhibited by a logic signal applied to the connector pin 2. If the inhibit function is not used pin 2 should be connected to pin 23 to enable the outputs.LED indicators display the status of the converter and allow visual monitoring of the system at any time. Full input to output, input to case, output to case, and output to output isolation is provided. The converters are designed and built according to the international safety standard IEC/EN 60950-1 and UL/CSA 60950-1, and they have been approved by the safety agencies TÜV and UL.The case design allows operation at nominal load up to 71°C in a free-air ambient temperature. If forced cooling is provided, the ambient temperature may exceed 71°C but the case temperature should remain below 95°C under all conditions.A temperature sensor generates an inhibit signal, which disables the outputs, when the case temperature TC exceeds the limit. The outputs automatically recover, when the temperature drops below the limit.
