Features include full power factor correction, high efficiency, high reliability, low output voltage noise and excellent dynamic response to load/line changes. The converter inputs are protected against surges and transients occurring at the source lines. An input over- and undervoltage lock-out circuitry disables the outputs if the input voltage is outside the specified range. Inrush current limitation is included preventing circuit breakers and fuses from being damaged at switch-on. All outputs are overload, open- and short-circuit proof and are protected against overvoltages by means of a built-in suppressor diode. The outputs can be inhibited by a logic signal applied to the connector pin 18 (i). If the inhibit function is not used pin 18 must be connected to pin 14 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 modules are designed and built according to the international safety standards IEC/EN 60950 and have been approved by the safety agencies LGA (Germany) and UL (USA). The UL Mark for Canada has been officially recognized by regulatory authorities in provinces across Canada. 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 must remain below 95 °C under all conditions. A temperature sensor generates an inhibit signal which disables the outputs if the case temperature TC exceeds the limit. The outputs are automatically re-enabled when the temperature drops below the limit. Various options are available to adapt the converters to individual applications. The modules may either be plugged into 19" rack systems according to DIN 41494, or be chassis mounted. Important: These products are intended to replace the LS 1000 and LS 2000 in order to comply with IEC/EN 61000-3-2.

This converter provides a sinusoidal input current (IEC/EN 61000-3-2, class D equipment) and sources a capacitor with a voltage of 360-370 V DC. This capacitor sources a single transistor forward converter. 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 Uo1 and generates, with respect to the maximum admissible output currents, the control signal for the primary switching transistor. The second output of double output units is controlled by the main output, but has independent current limiting. If the main output is driven into current limitation, the second output voltage will fall as well and vice versa.

Valid for -7 versions with NTC, (-9 versions exclude the NTC). Initial switch-on cycle. Subsequent switch-on/off cycles increase the inrush current peak value. AC frequency range 47...63 Hz. For DC-input please ask your local Power-One partner. Input Fuse A fuse mounted inside the converter protects the module against severe defects. (If operated from a DC-source this fuse may not fully protect the module when the input voltage exceeds 200 V DC! In applications where the converters operate at source voltages above 200 V DC an external fuse or a circuit breaker at system level should be installed!) Reverse Polarity Protection Should the input voltage to the unit be supplied from a DC source the built-in bridge rectifier provides reverse polarity protection. (For DC-input operation, please consult your local Power-One partner.) Inrush Current Limitation The modules of the versions -7, incorporate an NTC resistor in the input circuitry which – at initial turn on – reduces the peak inrush current value by a factor of 5...10 to protect connectors and switching devices from damage. Subsequent switch-on cycles within short periods will cause an increase of the peak inrush current value due to the warming-up of the NTC resistor. See also: E option. Inrush Current Peak Value The inrush current peak value (initial switch-on cycle) can be determined by following calculation: Ui rms • √2 Iinr p = –––––––––––––––– (Rs ext + Ri + RNTC) 04001 Table 3: Fuse Specification Module LS 1 1 Fuse type slow-blow Fuse rating SP T 4 A, 250 V Fuse size 5 × 20 mm Input Under-/Overvoltage Lock-out If the input voltage remains below approx. 65 V AC or exceeds approx. 280 V AC an internally generated inhibit signal disables the output(s).

Between Ui min and the undervoltage lock-out level the output voltage may be below the value defined in table: Output data (see: Technical Information: Measuring and Testing).

Edition 01/01.2001 8/27 Cassette Style Thermal Considerations 100 Watt AC-DC Converters Parallel or Series Connection of Units S Series PFC If a converter is located in free, quasi-stationary air (convection cooling) at the indicated maximum ambient temperature TA 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 TC (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 and temperature of surrounding components and surfaces. TA max is therefore, contrary to TC max, an indicative value only. Caution: The installer must ensure that under all operating conditions TC remains within the limits stated in the table: Temperature specifications. Notes: Sufficient forced cooling or an additional heat sink allows TA to be higher than 71 °C (e.g. 85 °C) if TC max is not exceeded. For -7 or -9 units at an ambient temperature TA of 85 °C with only convection cooling, the maximum permissible current for each output is approx. 40% of its nominal value as per figure. Io /Io nom Forced cooling 1.0 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 05089 Single or double output units with equal nominal output voltage can be connected in parallel without any precautions using option T. With option T (current sharing), all units share the current approximately equally. Single output units and/or main and second outputs of double output units can be connected in series with any other (similar) output. Note: – Parallel connection of double output units should always include both, main and second output to maintain good regulation of both outputs. – Not more than 5 units should be connected in parallel. – Series connection of second outputs without involving their main outputs should be avoided as regulation may be poor. – The maximum output current is limited by the output with the lowest current limitation if several outputs are connected in series.

Fig. 8 Output current derating versus temperature for -7 and -9 units. Thermal Protection A temperature sensor generates an internal inhibit signal which disables the outputs if the case temperature exceeds TC max. The outputs are automatically re-enabled if the temperature drops below this limit. It is recommended that continuous operation under simultaneous extreme worst case conditions of the following three parameters be avoided: Minimum input voltage, maximum output power and maximum temperature. Output Protection Each output is protected against overvoltage which could occur due to a failure of the control circuit by means of a voltage suppressor diode which, under worst case conditions, may become a short circuit. The suppressor diodes are not designed to withstand externally applied overvoltages. Overload at any of the two outputs will cause a shut-down of both outputs. A red LED indicates the overload condition. Uo2 is dependent upon the load distribution. If both outputs are loaded with more than 10% of Io nom, the deviation of Uo2 remains within ±5% of the value of Uo1. The following 3 figures show the regulation with varying load distribution. If Io1 = Io2 or the two outputs are connected in series, the deviation of Uo2 remains within ±1% of the value of Uo1 provided that a total load of more than 10% of Io nom is applied. Two outputs of a single S 5000 module connected in parallel will behave like the output of a S 4000 module; the paralleled output is fully regulated. No precautions are necessary in using the R-input and the test sockets.
