2 / 4 page  Model Selection Guide www.micropowerdirect.com Notes: 1. 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) |
