cassette style dc-dc converters m series edition 01/01.2001 4/25 functional description the input voltage is fed via an input fuse, an input filter, a rectifier 3 and an inrush current limiter 4 to the input capaci- tor. this capacitor sources a single transistor forward con- verter. each output is powered by a separate secondary winding of the main transformer. the resultant voltages are rectified and their ripples smoothed by a power choke and an output filter. the control logic senses the main output voltage u o1 and generates, with respect to the maximum admissible output currents, the control signal for the pri- mary switching transistor. this signal is fed back via a cou- pling transformer. the auxiliary outputs u o2 and u o3 are individually regulated by means of secondary switching transistors. each aux- iliary output's current is sensed using a current transformer. if one of the outputs is driven into current limit, the other out- puts will reduce their output voltages as well because all output currents are controlled by the same main control cir- cuit. fig. 1b block diagram, class ii equipment (double insulation) 1 transient suppressor diode in am, bm, cm, fm and cmz types. 2 bridge rectifier in lm and lmz, series diode in em types. 3 inrush current limiter (ntc) in cm, dm, em, lm and cmz, dmz, lmz types (option e: refer to the description of option e). 4 single output modules am...lm 1000 and cmz...lmz 1000 with feature r. for output configuration please refer to table: pin allocation . fig. 1a block diagram, class i equipment input filter output 1 filter output 3 filter output 2 filter control circuit main control circuit control circuit 1 fuse p 29 11 8 23 5 26 32 17 14 20 2 14 17 3 2 forward converter approx. 70 khz 4 4 c y c y c mkt c mkt vi+ vi C i d/v r g 03009 input filter output 1 filter output 3 filter output 2 filter control circuit main control circuit control circuit 1 fuse p 29 11 8 23 5 32 17 14 20 2 14 17 3 2 forward converter approx. 70 khz 4 4 c mkt c mkt vi+ vi C i d/v r g c y c y 03010

cassette style dc-dc converters m series edition 01/01.2001 6/25 input fuse a fuse holder containing a slow-blow type fuse (dimension: 5 20 mm) is mounted in the converter's back plate. the fuse protects the module against severe defects. it may not fully protect the module at input voltages exceeding 200 v dc. in applications where the converters operate at dc source voltages above 200 v dc, an external fuse or a circuit breaker at system level should be installed. for applications where the fuse should be inaccessible: see option f . input under-/overvoltage lock-out if the input voltage remains below 0.8 u i min or exceeds 1.1 u i max (approx. values), an internally generated inhibit signal disables the output(s). when checking this function the absolute maximum input voltage rating u i abs must be carefully considered (see table: input data ). between u i min and the undervoltage lock-out level the output voltage may be below the value defined in table: output data (see: tech- nical information: measuring and testing ). u i dc ________ u i min dc 23456 1 0.10 1.00 10.00 am i i [a] lm/lmz bm fm cm/cmz dm/dmz em 04014 350 300 50; 250 40; 200 30; 150 20; 100 10; 50 0 400 0 0.8 2.0 1.0 2.5 1.2 3.0 1.4 3.5 1.6 4.0 0.6 1.5 0.4 1.0 0.2 0.5 am bm cm/cmz fm em a em lm i i [a] lm/lmz dm/dmz t [ms] lm a em 04015 fig. 3 typical inrush current at initial switch-on cycle and at u i max [dc] versus time fig. 2 typical input current versus relative input voltage at nominal output load reverse polarity reverse polarity at the input of am, bm, cm, dm, fm and cmz, dmz types will cause the fuse to blow. in em, lm and lmz types a series diode will protect the module. a series diode is not incorporated in am, bm, cm, dm, fm and cmz, dmz types to avoid unwanted power loss. inrush current the cm, dm, em, lm and cmz, dmz, lmz (excluding fm) modules incorporate an ntc resistor in the input circuitry which (during the initial switch-on cycle) limits the peak in- rush current to avoid damage to connectors and switching devices. subsequent switch-on cycles within a short inter- val will cause an increase of the peak inrush current due to the warming up of the ntc resistor. refer also to: option e description. table 3: fuse types (slow-blow) series schurter type part number am 1000...3000 spt 10 a 250 v 0001.2514 bm 1000...3000 spt 8 a 250 v 0001.2513 fm 1000...3000 spt 5 a 250 v 0001.2511 cm/cmz 1000...3000 spt 3.15 a 250 v 0001.2509 dm/dmz 1000...3000 spt 2.5 a 250 v 0001.2508 em 1000...3000 lm/lmz 1000...3000

cassette style dc-dc converters m series edition 01/01.2001 8/25 thermal protection a temperature sensor generates an internal inhibit signal which disables the outputs if the case temperature exceeds t c max . the outputs are automatically re-enabled if the tem- perature drops below this limit. output protection each output is protected against overvoltages which could occur due to a failure of the internal control circuit. voltage suppressor diodes (which under worst case condition may become a short circuit) provide the required protection. the suppressor diodes are not designed to withstand externally applied overvoltages. overload at any of the outputs will cause a shut-down of all outputs. a red led indicates the overload condition of the respective output. parallel and series connection main outputs of equal nominal voltage can be connected in parallel. it is important to assure that the main output of a multiple output module is forced to supply a minimum cur- rent of 0.1 a to enable correct operation of its own auxiliary outputs. in parallel operation, one or more of the main outputs may operate continuously in current limitation which will cause an increase in case temperature. consequently, a reduction of the max. ambient temperature by 10 k is recommended. main or auxiliary outputs can be connected in series with any other output of the same or another module. in series connection, the maximum output current is limited by the lowest current limit. output ripple and regulation values are added. connection wiring should be kept as short as possi- ble. if output terminals are connected together in order to estab- lish multi-voltage configurations, e.g. +5.1 v, 12 v etc. the common ground connecting point should be as close as possible to the connector of the converter to avoid exces- sive output ripple voltages. auxiliary outputs should never be connected in parallel! thermal considerations if a converter is located in free, quasi-stationary air (con- vection cooling) at the indicated maximum ambient tem- perature t a max (see table: temperature specifications) and is operated at its nominal input voltage and output power, the temperature measured at the: measuring point of case temperature t c (see: mechanical data ) will approach the indicated value t c max after the warm-up phase. however, the relationship between t a and t c depends heavily on the conditions of operation and integration into a system. the thermal conditions are influenced by input voltage, output current, airflow and temperature of surrounding compo- nents and surfaces. t a max is therefore, contrary to t c max , an indicative value only. caution: the installer must ensure that under all operat- ing conditions t c remains within the limits stated in the table: temperature specifications. notes: sufficient forced cooling or an additional heat sink allows t a to be higher than 71 c (e.g. 85 c) if t c max is not exceeded. for -7 or -9 units at an ambient temperature t a of 85 c with only convection cooling, the maximum permissible current for each output is approx. 50% of its nominal value as per figure. 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 50 60 70 80 90 100 i o / i o nom t a [ c] 0.9 1.0 forced cooling 05031 t a min t c max convection cooling fig. 6 output current derating versus temperature for -7 and -9 units. 1.0 0 0.5 u o1 0.5 u o1 nom i o i o nom 1.0 1.2 i o nom i o1 i o2 , i o3 i ol1 i ol2 , i ol3 .95 05022 i o / i o nom 1 u od u od t d t d d u o i d u o i t u o 0 t 10 s 10 s 05010 fig. 4 typical output voltage u o1 versus output currents i o . fig. 5 dynamic load regulation u o d versus load change.
