The single-output versions have a continuous power output rating of 570W. The LX550 cannot operate without fan cooling. 2 Peak power figures for individual outputs on the multiple output unit are for less than 10 seconds duration. Total output power should not exceed 550W. 3 Fan fitted as standard, see maximum output current specifications. 4 Single output models are adjustable -8%, +16%. 5 A 10% load on the main output is necessary to maintain regulation on the auxiliaries at full load (multiple output model). 6 The input board is fitted with an autorange circuit as standard which automatically senses the input voltage and switches to the appropriate voltage range. 7 Over temperature protection is provided by a thermal switch fitted to the main transformer. After thermal shutdown (90 °C) the unit must be powered down and the thermal switch must be allowed cool to 70 °C before power up. 8 This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. Options • DC input models for 24V and 48V operation are detailed on page 170. • A signals board is available as an option. To order, add the suffix ‘-S’, see table below. OPTIONS SUFFIX EXAMPLE None LX550-7620 Signals -S LX550-7620-S OVERLOAD/SHORT CIRCUIT PROTECTION The overload/short circuit protection mechanisms are different for the single output models and the multiple output model. The single output models will current limit when the output load reaches 105-120% of maximum load during overload or short circuit conditions. The unit will operate in a constant current mode making the single output models suitable for battery charging applications. The multiple output model uses a power limiting function. When the total output power reaches 600W the outputs will foldback to the values detailed below: Output Foldback Value +5V 30A continuous +12V 8A continuous +24V 4A continuous –5V/–12V Protected by 4A Multi Fuse™ The outputs will not foldback until the total output power exceeds the maxi- mum power limits. This allows the units to have a peak power capability but it requires that care must be taken not to permanently overload any individual output. The +5V, +12V and +24V outputs are not individually pro- tected and it is recommended that the maximum continuous load does not exceed the value given in the output specifications. The -5V and -12V out- puts are individually protected by a 4A Multi Fuse™ and the maximum con- tinuous load should not exceed the value given in the output specifications. SIGNALS (OPTIONAL) An optional signals board supplies the following VME utility bus signals: ACF (AC Fail) Logic 1 to 0 transition occurs >10ms before outputs fall below 90% of nominal in the event of input failure. DCF (DC Fail) Logic 0 occurs if output falls below <85%–95% of nominal. SRS (System Reset) Logic 1 for system OK (AC and DC good and reset times [200ms]) PM Power Monitor signal, proportional to the output power, ratio of 10mV/W. PS Power Share connections, to be joined for parallel operation of two or more units, ensuring equal power share. For power share operation unit outputs need to be set to ±5% of each other and should be connected in star configurations with the load as star centre.
