When measuring output ripple, it is recommended that an external ceramic capacitor (approx 10 µF) be placed from the +VOUT to the -VOUT pins. 2. Transient recovery is measured to within a 1% error band for a load step change of 25%. 3. Short circuit protection is provided by a “hiccup mode” circuit. 4. 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. 5. These units should not be operated over +85°C. Exceeding +85°C may damage the unit. 6. It is recommended that a fuse be used on the input of a power supply for protection.

To meet the requirements of EN 61000-4-4 (±2 kV), external components are needed. This can be done discretely, or with the addition of the MDCFM-40U. Contact the factory for more information. 5. To meet the requirements of EN 61000-4-5 (±2 kV/±4 kV), external components are needed. This can be done discretely, or with the addition of the MDCFM-40U. Contact the factory for more information. 5. Suggested component values are: the MRxx11S product series, the MDCFM-40U DC filter modules are recommended. For pricing or Input Vout Output full technical information, please Vin (VDC) Capacitor (VDC) Capacitor contact the factory. 7. In many applications simply 5 470 µF adding input/output capaci12 220 µF 110 100 µF tors will enhance the input 15 220 µF surge protection and reduce 24 100 µF output ripple sufficiently. In this case, the capacitors C1 and C3 would be connected as shown without the other filter components. Recommended capacitor values are given in the table above.. Typical Connection The diagram above illustrates a typical connection of the MR1011S series The MDCFM-40U filter module is used to make the circuit compliant with input surge and EMC standards EN 55022, EN61000 and EN 50155. This can also be accomplished by using external filter components as shown in the board layout drawing below. Some notes on these components are: 1. It is recommended that an external fuse be used. The recommended fuse is shown in the model chart on page 2. 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. An external TVS is recommended on the input to protect the unit in the event of a voltage spike. A recommended value is given in the table at right. 4. The output filtering capacitor (C3) is a high frequency, low resistance electrolytic capacitor. Care must be taken in choosing this capacitor not to exceed the capacitive load specification for the unit. Voltage derating of capacitors should be 80% or above.
