The specified maximum capacitive load is for each output. 2. Start up time is specified at the nominal Voltage input and with a constant resistive load. 3. Load regulation is specified for a load change of 0% to 100%. 4. Cross regulation is specified with one output at full load while the other output is varied from 25% to 100% load. 5. Output ripple is measured with a 1 μF ceramic capacitor and a 10 μF electrolytic capacitor connected in parallel. 6. Transient recovery is measured to within a 1% error band for a load step change of 25%. Single 3.3 & 5 VDC output models have a response deviation of ±5.0% Max. 7. Isolation voltage ratings are for 60 seconds. 8. With the addition of external filter and protection components, all models will meet the requirements of EN 55032 class A. Suggested input circuits are shown in the connection diagrams on page 3. Contact the factory for more information. 9. To meet the requirements of EN 61000-4-4 (±2 kV), external components are needed. The connection diagrams on page 3 shows external components that would typically achieve this. Contact the factory for more information. 10. To meet the requirements of EN 61000-4-5 (±2 kV), external components are needed. This can be done as shown in the connection diagrams on page 3. Contact the factory for more information. 11. Operation at no-load will not damage the unit, but they may not meet all specifications. 12. 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. Remote ON/OFF Control The MD900x-RU may be started or shutdown by the control pin input (pin 3). This input is current controlled. The unit operates when this input is left open. When the input is “high” (current is flowing into the pin), the converter shuts down. The input current to this pin must be kept between 2 mA to 4 mA. The diagram at right shows a simple input circuit for the control pin. Closing the switch causes 2 - 4 mA to flow through the 1 k⍀ resister, shutting the unit off.

Some notes on this diagram (starting with the input circuit) are: www.micropowerdirect.com 3. The output filtering components C9 & C11 are high frequency, low ESR electrolytic capacitors. Capacitors C10 & C12 are ceramic. Care must be taken in choosing 1. An external fuse should be used in all power module applications. The recommended these capacitors not to exceed the capacitive load specification for the unit. Voltage fuse is shown in the model chart on page 2. derating of capacitors should be 80% or above. 2. To protect against voltage spikes, it is recommended that a TVS be used on the input. A suggested value is given in the tables below.

These units also feature high power density, a very high performance envelope and a wide range of standard models. However, since thay are 2:1 input designs, they are offered at a lower cost. • 9W Output Power • Miniature SIP Case • 2:1 Input Voltage Range • 27 Single & Dual Output Models • 1,600 VDC Isolation Check them out now, or call the factory for free samples. • Miniature SIP Case • -40°C to +85°C Operation MicroPower Direct We Power Your Success - For Less! 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: [email protected]
