Notes
1 The multiple output LX350 has a continuous output power rating of 350W. The single-output versions have a continuous output power rating of 385W. Peak power figures for individual outputs on the multiple output unit are for less than 10 seconds duration. The overall peak power for the unit is 550W for 10 seconds duration. Single output models are adjustable -8%, +16%. A 10% load on the main output is necessary to maintain regulation on the auxiliaries at full load (multi output model). The input board is fitted with an autorange circuit as standard which automatically senses the input voltage and switches to the appropriate voltage range. This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. Consideration should be given to measuring the temperature on the main transformer (T1) when the power supply is installed in end-use equipment. The measured temperature on T1 must not exceed 90C.

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: Foldback Value Output +5V 30A continuous +12V 8A continuous +24V 4A continuous -5V/-12V Protected by 4A Multi FuseTM The outputs will not foldback until the total output power exceeds the maximum 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 protected and it is recommended that the maximum continuous load does not exceed the value given in the output specifications. The -5V and -12V outputs are individually protected by a 4A Multi FuseTM and the maximum continuous 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 80%-85% 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, 10%. 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.
