If output current of input power source is limited, the fuse may not blow out. [menial fuse ratings are as follows: Input PSS/PSD PSS/PSD PSS/PSD PSS/PSD voltage 1R5 3 6 10 5V 2.3A 4,0A 5.0A lOlOA 12V 1,2A 2.5A/2.3A 2.5A 5.0A 24V 0.7A 1.2A 2.0A 25A 48V 0.7A 0.7A 145A 2.0A DENSEl-LAMBDA
PSS-PSD SERIES 2. 5 Input Surge Current Input surge current flows for a short period of time during line throw-in. When using plural number of the units together following input currents are added. Please choose input switch and external fuse with proper current rating. Over Currant Protection (OCP) When OCP activates, output voltage drops. When over current condition is released, the output voltage is aummatically recovered Being in short or overload condition for more than 30 seconds may cause damage on fine unit. Due to fold back characteristics of OCP, the output may not rise up steady with constant current load or inductive load. Over Voltage Protection Over Voltage Protection is not provided in this PSS and PSD series. Input I Output Filter 1) Input Ripple and Noise An internal filter is provided in a unit, Unit can operation even without external input capacitor but attaching capacitor at input have effect in further reducing the noise, The external capacitor shall be attached as close as possible to input terminal of PSS and PSD series. PSS/PSD1R5,3,6 PSS/PSDIO +Vin When wire fi‘om input power source to PSS/PSD series is long, the impedance of input line is large and spike noise or inductance of input wire may exert a bad influence on the unit due to high impedance of input wire. In this case, attachment of external capacitor is recommended. Recommended capacitance of the external capacitor is 10~680 it F. Choose a suitable external capacitor in accordance with operating condition. 2) Output Ripple and Noise (l)To reduce output ripple, attachments of aluminum electrolytic capacitors are recommended at output, The capacitors shall be l~200 it P. Please adjust the maximum capacity of the capacitor to 1000 L: F or less. In addition, when using 200 h F~1000 it F capacitors characteristics are especially affect/ed. Therefore please perform sufficient evaluation before using this product When load is equal or less than 20% output ripple might increase. For this case, please add external circuit below.

Take note that output ripple voltage and output spike noise may vary depending on PCB wiring design. Generally, output ripple voltage and output spike noise can be reduced by unmeasing value of external capacitor, 7.

PSS-PSD SERIES 9. Series - Parallel Operation 1) Series Operation As shown in the following figure, it is possible to connect the units in series. If the output voltage does not start up in series connection, connect a diode with low forwm'd voltage ie, schouky barrier diode. Use diode that reverses voltage is more than twice the voltage between +Vout and —Vout. Also, the maximum forward current of the diode shall be sufficiently larger than the output current. Whichever smaller nominal current of a unit in series operation shall be maintained as the maximum output current. 2) An application of PSD series PSD series can be used as shown below figure. In this case, PSD series operate as if single output (24V output) \mits, - mm mm 3) Parallel Operation 10. 11 12 It is not allowed to connect in parallel to increase the output current, however, it is possible if the load current is less than the maximum output current of the unit. Operating Ambient Temperature The operating ambient oemperature is from -40°O~35°C. However, the output load should be derated accordingly to the ambient temperature and airflow speed (refer to derating curve of specification sheet). There is no restriction on mounting direction but there should be enough consideration for airflow so that heat does not accumulate around the power supply vicinity. Determine external components configuration and mounting direction on PCB such that airflow through the power supply from force air or convection cooling is not blocked. Operating Ambient Humidity Take note that moisture could lead to power supply abnormal operation or damage. Cooling Method The operating ambient temperature is from —40°O~85°C, However, the output load should be derailed accordingly to the ambient temperature and airflow speed (refer to derating curve of specification sheet). 10 DENSEI-LAMBDA
PSS- PSD SERIES 13 14 15 16 17 18 19 Isolation and Withstand Voltage Test Avoid performing the isolation resistance test with voltage that is over specification. At the withstand voltage test, the voltage shall be gradually increased to apply and decreased to shut down the input. Especially using timer, the impulse voltage several times as the applied voltage may break out at shutting down and cause of damage on the units. Vibration Vibration of power supply is defined in case of momting on PCB.

Safety Consideration LConsideration shall be given to measuring the ambient temperature around of power supply vicinity when the converter is installed in the end use equipment It must be ensured the temperature does not exceed 85 degrees Celsius. This temperature limit governs the working ambient temperature. 2,1118 input to the units must be isolated from the mains by reinforced insulation in accordance with I'EC/EN60950 Due to the potential nonvSELV Voltages at the input, the input to those units must he considered ahazerdous secondary voltage, outputs were considered SELV, see note 1 above. 11 DENSEl-LAMBDA

Relationship between current and pattern width changes depending on material of printed circuit board, thickness of conductor and temperature rise allowance. Fig. 2-1 shows an example of 3 35pm} copper glass epoxy printed circuit board. For example, when 5A of current flows and temperature rise below 10°C are expected, pattern width shall be more than 42mm with 3Sum copper plate (generally lmm/A is standard).
