S Series Data Sheet 100 Watt AC-DC and DC-DC Converters Features Input voltage ranges from 8 to 385 VDC and 85 to 264 VAC, 47-440 Hz 1or 2 isolated outputs up to 48 VDC Class I equipment * RoHS lead solder exemption compliant * Extremely-wide input voltage range * Input over- and undervoltage lockout * Efficient input filter and built-in surge and transient suppression circuitry * Outputs: SELV, no-load, and short-circuit proof * No derating over entire operating temperature range * PCBs coated with protective lacquer 111 4.4" 3U 60 2.4" 12 TE * Very high reliability 168 6.6" Safety according to IEC/EN 60950 Description The S Series AC-DC and DC-DC converters represents a broad and flexible range of power supplies for use in advanced electronic systems. Features include high efficiency, high reliability, low output voltage noise and excellent dynamic response to load/line changes. LS models can be powered by DC or AC with a wide-input frequency range (without PFC). The converter inputs are protected against surges and transients. An input over- and undervoltage lockout circuitry disables the outputs if the input voltage is outside of the specified range. Certain types include an inrush current limiter preventing circuit breakers and fuses from tripping 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 pin 18 (i). If the inhibit function is not used, pin 18 must be connected with pin 14 to enable the outputs. LED indicators display the status of the converter and allow for visual monitoring of the system at any time. 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 converters may either be plugged into a 19" rack system according to IEC 60297-3, or be chassis mounted. They are ideally suited for Railway applications. Important: For applications requiring compliance with IEC/EN 61000-3-2 (harmonic distortion), please use our LS4000 and LS5000 Series with incorporated power factor correction (PFC). Full input-to-output, input-to-case, output-to-case and output-tooutput isolation is provided. The converters are designed and built according to the international safety standards IEC/EN 60950 and EN50155. They have been approved by the safety agencies TUV and UL (for USA and Canada).

APR 26, 2006 revised to SEP 25, 2006 Page 3 of 33 www.power-one.com S Series Data Sheet 100 Watt AC-DC and DC-DC Converters Functional Description The input voltage is fed via an input fuse, an input filter, a bridge rectifier (LS), and an inrush current limiter to the input capacitor. 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 ripple smoothed by a power choke and output filter. The control logic senses the main output voltage Vo1 and generates, with respect to the maximum admissible output currents, the control signal for the primary switching transistor. The second output of double-output models 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.

This is the nominal value at 25 C and applies to cold models at initial switch-on cycle. Subsequent switch-on/off cycles increase the inrush current peak value. 3 For 1 s max. 4 AC operating frequency range is 47 to 440 Hz (440 Hz for 115 V mains). For frequencies 63 Hz refer to Safety and Installation Instructions. Input Transient Protection tolerance of -30% to 25%. A suppressor diode and/or a VDR (depending on input voltage range) together with the input fuse and a symmetrical input filter form an effective protection against high input transient voltages which typically occur in most installations, but especially in battery-driven mobile applications. In certain applications, surges according to RIA 12 are specified in addition to those defined in IEC 60571-1. The power supply must not switch off during these surges and since their energy can practically not be absorbed an extremely wide input range is required. The ES input range for 110 V batteries has been designed and tested to meet this requirement. Nominal battery voltages in use are: 12, 24, 36, 48, 60, 72, 110, and 220 V. In most cases each nominal value is specified in a APR 26, 2006 revised to SEP 25, 2006 Page 5 of 33 www.power-one.com S Series Data Sheet 100 Watt AC-DC and DC-DC Converters Input Fuse A fuse mounted inside the converter protects the module against severe defects. This fuse may not fully protect the module when the input voltage exceeds 200 VDC! In applications where the converters operate at source voltages above 200 VDC an external fuse or a circuit breaker at system level should be installed! The inrush current peak value (initial switch-on cycle) can be determined by following calculation: Vi source Iinr p = ---------------- (Rs ext + Ri + RNTC) 05109_060805 Table 3: Fuse Specification Model 1 AS BS 1 CS 2 DS 2 ES 2 FS 2 LS 2 1 Rs ext Fuse type Reference Rating fast-blow fast-blow slow-blow slow-blow slow-blow slow-blow slow-blow Little fuse 314 Little fuse 314 SPT SPT SPT SPT SPT 30.0 25.0 12.5 8 4 16 4 2 Fuse size 6.3 x 32 mm A, A, A, A, A, A, A, + 125 V 125 V 250 V 250 V 250 V 250 V 250 V Iinr p RNTC Ri Ci int Vi source Fig. 4 Equivalent circuit for input impedance Fuse size 5 x 20 mm Static Input Current Characteristic Inrush Current The CS, DS, ES, and LS models (not -9, not option E) incorporate an NTC resistor in the input circuitry, which at initial turn-on reduces the peak inrush current value by a factor of 5 to 10. Subsequent switch-on cycles within short periods increase the inrush current due to the hotter NTC resistor.

APR 26, 2006 revised to SEP 25, 2006 The converters (except LS) are not protected against reverse polarity at the input, but in general, only the input fuse will trip. LS models are fully protected due to the built-in bridge rectifier. Input Under-/Overvoltage Lockout If the input voltage remains below approx. 0.8 Vi min or exceeds approx. 1.1 Vi max, an internally generated inhibit signal disables the output(s). When checking this function the absolute maximum input voltage rating Vi abs should be considered! Between Vi min and the undervoltage lockout level the output voltage may be below the value defined in table: Electrical Output Data.

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. 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. Caution: The installer must ensure that under all operating conditions TC remains within the limits stated in the table Temperature specifications. Parallel or Series Connection Single or double-output models with equal nominal output voltage can be connected in parallel without any precautions using Option T (current sharing). Single output models and/or main and second outputs of doubleoutput models can be connected in series with any other (similar) output. Notes: 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 models at ambient temperature TA = 85 C with only convection cooling, and the maximum permissible current for each output is approx. 40% of its nominal value as per the figure below. - Parallel connection of double output models should include both, main and second output to maintain good regulation of both outputs. - Not more than 5 models should be connected in parallel. - Series connection of second outputs without involving their main outputs should be avoided as regulation may be poor. - Rated output voltages above 36 V need additional measures in order to comply with the safety requirements for SELV (Safe Extra Low Voltage) Io /Io nom - The maximum output current is limited by the output with the lowest current limitation if several outputs are connected in series.

If both outputs are loaded with more than 10% of Io nom, the deviation of Vo2 remains within 5% of the value of Vo1. The following 3 figures show the regulation with varying load distribution.

Option -9: Extended Temperature Range Option -9 extends the operational ambient temperature range from -25 to 71 C to -40 to 71 C. The power supplies provide full nominal output power with convection cooling. Option -9 excludes inrush current limitation by NTC. Option E: Inrush Current Limiter CS/DS/ES/FS/LS types may be supplemented by an electronic circuit (option E, replacing the standard built-in NTC) to achieve an enhanced inrush current limiting function. Option E is mandatory for -9 models. CS models fitted with option E and option D6 (input voltage monitoring) meet the standard ETS 300132-2 for 48 VDC supply voltage. Option D6 (externally adjustable via potentiometer from 36.0 to 40.5 V) is necessary to disable the converter at low input voltages, avoiding an excessive input current. Option D6 threshold level should be adjusted to 44.0 - 50.0 V for 60 V nominal supply systems (refer to the description of option D). The D output can be connected directly to the inhibit input.

To use this facility, simply interconnect the T pins of all converters and make sure that the reference pins for the T-pin (S- for the S1000 or Vo1- for S2000) are also connected together. The load lines should have equal length and cross section to ensure equal voltage drops. Not more than 5 converters should be connected in parallel.

Page 28 of 33 www.power-one.com S Series Data Sheet 100 Watt AC-DC and DC-DC Converters Option V: ACFAIL Signal (VME) Available only for models with Vo = 5.1 V. Formula for the external input capacitor: This option defines an undervoltage monitoring circuit for the input and main output voltage. It generates an ACFAIL signal (V signal) which conforms to the VME standard. 2 * Po * (th + 0.3 ms) * 100 Ci ext = ---------------------- - Ci min * (Vti 2 - Vi min2) The low state level of the ACFAIL signal is specified at a sink current of IV 48 mA to VV 0.6 V (open-collector output of an NPN transistor). The pull-up resistor feeding the open-collector output should be placed on the VME backplane. After the ACFAIL signal has gone low, the VME standard requires a hold-up time (th) of at least 4 ms before the 5.1 V output drops to 4.875 V when the output is fully loaded. The hold-up time is provided by the internal input capacitance. Consequently, the working input voltage and the threshold level (Vti) should be adequately above the minimum input voltage (Vi min) of the converter so that enough energy is remaining in the input capacitance. If the input voltage is below the required level, an external hold-up capacitor (Ci ext) should be added. Formula for threshold level for desired value of th: Vti = where as: Ci min = internal input capacitance [mF] Ci ext = external input capacitance [mF] Po = output power [W] th = efficiency [%] = hold-up time [ms] Vi min = minimum input voltage [V] 1 Vti = threshold level [V] 1 Min. input voltage according to Electrical Input Data.
