Cross regulation is measured with output V1 and one auxiliary output at 100% load. The second auxiliary output is varied from 25% to 100% load. 2. When measuring output ripple, it is recommended that an external ceramic capacitor (approx 4.7 - 10 µF) be placed from each output to common. 3. Transient recovery is measured to within a 1% error band for a load step change of 25%. 4. Short circuit protection is provided by a “hiccup mode” circuit. 5. If the on/off pin is left open, the unit operates. If it is grounded, the unit will shut off. THe control circuit is referenced to the minus (-) input. 6. These units should not be operated with a load under 10% of full load. Operation at no-load will not damage the unit, but they may not meet all specifications. 7. These units should not be operated over +85°C. Exceeding +85°C may damage the unit. 8. It is recommended that a fuse be used on the input of a power supply for protection. It is recommended that a slow blow fuse rated at 6,000 mA be used with the 24V input models and a 3,000 ma fuse be used with 48V input models.

The units do not require external components to operate as specified. Some notes on this diagram (starting with the input circuit) are: 1. It is recommended that an external fuse be used. The recommended fuse is shown in the table at right. 2. An external MOV is recommended on the input to protect the unit in the event of a surge. A recommended value is given in the table at right. 3. The output filtering capacitors (C4, C5, C6) are high frequency, low resistance electrolytic capacitors. Care must be taken in choosing these capacitors not to exceed the capacitive load specification for the unit. Voltage derating of capacitors should be 80% or above.

All units are rated for EN 55022 (CE/RE) class A without external components. They will meet class B with the addition of a discrete filter circuit like that illustrated below. Contact the factory for more information. 2. To meet the requirements of EN 61000-4-4 (±2 kV), external components are needed, as shown on the typical connection diagram below. 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, as shown in the typical connection diagram below. Contact the factory for more information. 6. 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 C4, C5 and C6 shown in the typical connection/board layout drawings below show their connection. In this case, recommended capacitor values are: CIN: 10 µF COUT: 10 µF for 3.3V/5 V Outputs 4.7 µF for 12V/15V Outputs Typical Connection Typical Board Layout: With External Filter/Surge Components 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 Function 1 +VIN 2 -VIN 4 Remote On/Off 5 +VOUT2 6 +VOUT1 7 Common 8 -VOUT2 Mechanical Dimensions: With Optional Heatsink For the heatsink option, add suffix “H” to the model number (i.e. MF3048T-0512ERU-H) MicroPower Direct Notes: • All dimensions are typical in inches (mm) • Tolerance x.xx = ±0.02 (±0.50) 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]
