Cross regulation is measured with the output being tested at 100% load while the other output is varied from 25% to 100% load. 2. See the typical connection circuit on page three for typical external filtering components. For help with a specific model or layout issue, contact the factory. 3. Isolation voltage is specified for Input to output. On units with the optional metal case, the isolation voltage for Input - Case and Output - Case is 1,000 VDC. 4. Operation at no-load will not damage the unit, but they may not meet all specifications. To meet all specifications, a minimum load of 25% should be maintained. 5. It is recommended that a fuse be used on the input of a power supply for protection. See the Model Selection table above for the correct rating. For the alternate pin-out (see page 4) , add suffix “P2” to model number (i.e. MA524S-05RWI-P2) Model Number Derating Curve 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: [email protected] www.micropowerdirect.com Typical Connection The diagram above illustrates a typical connection of the MA500RWI series for applications that require meeting conducted EMC standards. The units do not require external components to operate as specified. For applications requiring very low output noise levels, the output filtering capacitors (C3 is a low ESR electrolytic & C4 is a ceramic) will often be sufficient. Care must be taken in choosing output capacitors not to exceed the capacitive load specification for the unit. For dual output units, output capacitors should be connected from each output to common. All external components should be mounted as close to the unit as possible. The recommended values for components are: Component 24 VIN 48 VIN 12 VIN C1 220 µF/50V 220 µF/100V 220 µF/100V LCM 12 µH 12 µH 12 µH --470 pF/4kV MLCC 470 pF/4kV MLCC C2 100 µF 100 µF 100 µF C3 4.7 - 10 µF 4.7 - 10 µF 4.7 - 10 µF C4 Typical Board Layout: With External Filter Components, Single Output Typical Board Layout: With External Filter Components, Dual Output Input noise and surge suppression modules are available for a number of MPD DC/DC power supplies.
