When measuring output ripple & noise, it is recommended that an external capacitor (1 µF to 10 µF) be placed from the +VOUT to the -VOUT pins for single output units and from each output to common for dual output models.. 2. Transient recovery is measured to within a 1% error band for a load step change of 25%. 3. 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. 4. It is recommended that a fuse be used on the input of a power supply for protection.

All units are rated for EN 55022 (CE/RE) class A without external components. They will meet class B with the addition of the MDCFM-02A(W) (or a similar discrete filter circuit). Contact the factory for more information. 2. To meet the requirements of EN 61000-4-4 (±2 kV), external components are needed. This can be done discretely as shown in the typical connection diagram below. With the addition of the MDCFM-02A(W), the unit will meet EN 61000-4-4 (±4 kV). Contact the factory for more information. 3. To meet the requirements of EN 61000-4-5 (±2 kV), external components are needed. This can be done discretely, or with the addition of the MDCFM-02A(W). Contact the factory for more information. Typical Connection The diagram above illustrates a typical connection of the MA300xERW series 5. Recommended values for components are: for applications that require meeting EMC standards. The units do not require Component 12 VIN 24 VIN 48 VIN 5 VIN external components to operate as specified. Some notes on this diagram (starting MOV ----S14K35 S14K60 with the input circuit) are: LDM1 ----56 µH 56 µH 1. It is recommended that an external fuse be used. The recommended fuse is TVS SMCJ13A SMCJ28A SMCJ48A SMCJ90A shown in the model chart on page 2. 2. An external MOV is recommended on the input to protect the unit in the event C1 680 µF/16V 680 µF/25V 330 µF/50V 330 µF/100V of a surge. A recommended value is given in the table at right. C2 4.7 µF/50V 4.7 µF/50V 4.7 µF/50V 4.7 µF/100V 3. An external TVS is recommended on the input to protect the unit in the event LDM2 12 µH 12 µH 12 µH 12 µH of a voltage spike. A recommended value is given in the table at right. C3 4.7 µF/50V 4.7 µF/50V 4.7 µF/50V 4.7 µF/100V 4. The output filtering capacitor (C5) is a high frequency, low resistance electrolytic C4 1 nF/2 kV 1 nF/2 kV 1 nF/2 kV 1 nF/2 kV capacitor. Care must be taken in choosing this capacitor not to exceed the capacitive load specification for the unit. Voltage derating of capacitors should C5 10 µF 10 µF 10 µF 10 µF be 80% or above. C6 10 µF 10 µF 10 µF 10 µF 6. Input noise and surge suppression modules are available for a number of MPD DC/DC power supplies. For pricing or full technical information, please contact the factory. 7. In many applications simply adding input/output capacitors will enhance the input surge protection and reduce output ripple sufficiently. The input capacitor C1 and output capacitors C5 and C6 shown in the typical connection diagram above (& board layout drawing below), illustrate their connection. The recommended capacitor values are as follows: CIN COUT 5V/12V Input: 24V/48V Input All Models 100 µF 10µF - 47 µF 10µF/100mA Typical Board Layout: With External Filter/Surge Components for Single Output Unit Typical Connection: With External Filter/Surge Components for Dual Output Unit MicroPower Direct • 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: [email protected] www.micropowerdirect.com Mechanical Dimensions Pin Connections Pin 2 3 9 11 14 16 22 23 Single Output -VIN -VIN No Pin No Connection +VOUT -VOUT +VIN +VIN Pin 2 3 9 11 14 16 22 23 Dual Output -VIN -VIN Common -VOUT +VOUT Common +VIN +VIN Notes: • All dimensions are typical in inches (mm) • Tolerance x.xx = ±0.02 (±0.50) • Pin 1 is marked by a “dot” or indentation on the top of the unit Packing Tube Dimensions Notes: • • • • Tube length equals 20.866 (530), unit quantity equals 15 pcs.
