At no load, output voltage accuracy is ±1.5% typical and ±5.0% max. 2. The load on dual output units should not be unbalanced more than ±5 %. Units operated with unbalanced loads greater than ±5% may not meet all specifications. 3. When measuring output ripple & noise, it is recommended that an external capacitor (100 µF typ.) be placed from the +VOUT to the -VOUT pins for single output units and from each output to common for dual output models. 4. Transient recovery is measured to within a 1% error band for a load step change of 25%. 5. With the addition of the DCFM-0x (or a similar discrete filter), all models will meet EN 55022 class B. A suggested input circuit is shown in the connection diagram on page 3. Contact the factory for more information. 6. To meet the requirements of EN 61000-4-4 (±2 kV), external components are needed. The connection diagram on page 3 shows an external input filter that would typically achieve this. With the addition of the DCFM-0x, EN 61000-4-4 (±4 kV) can be achieved. Contact the factory for more information. 7. To meet the requirements of EN 61000-4-5 (±2 kV), external components are needed. This can be done discretely (as shown in the connection diagram on page 3), or with the addition of the DCFM-0x. Contact the factory for more information. 8. These units should not be operated with a load under 5% of full load. Operation at no-load will not damage the unit, but they may not meet all specifications. 9. 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.

This input is current controlled. The unit operates when this input is open. When the input is “high” (current is flowing into the pin), the converter shuts down. The input current to this pin should be kept between 5 mA to 10 mA. Exceeding 20 mA on this input or connecting it directly to ground could damage the converter. The diagram at right gives a suggested input circuit for the control pin. The diode (D1) is an RB160M-60/1A and CD is is a 47 nF/100V. The resistor R1 is determined by the formula: R = [(VC-VD-1.0)/IC]-300 Where: VC = voltage to ground from pin 3 VD = the forward conduction voltage drop of D1 IC = the control pin current (5 - 10 mA) 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: [email protected] Typical Connection www.micropowerdirect.com For applications that require meeting EMC standards, the diagram above 6.

CY 1nF/2 kV 1nF/2 kV 1nF/2 kV 1nF/2 kV 5. The output filtering capacitor (C4) is a high frequency, low resistance 10 µF - 22 µF CS electrolytic capacitor. Care must be taken in choosing this capacitor 100 µF 100 µF 100 µF 100 µF C4 not to exceed the capacitive load specification for the unit. Voltage derating of capacitors should be 80% or above. 7. The drawings below show typical board layouts for the EMC/ EMI circuit shown above (one for single output models and one for dual output units). 8. In many applications simply adding input/output capacitors will enhance the input surge protection and reduce output ripple sufficiently. The value of the input capacitor can range from 10 µF to 100 µF, depending on the needs of the application. The output capacitor would typically be 100 µF. 9. The capacitor CS provides additional output filtering. If used, a value of 10 µF to 20 µF is recommended. This capacitor is not required for specified operation.
