Start up time is measured at nominal input and with a constant resistive load. 2. When measuring output ripple, it is recommended that an external ceramic capacitor (approx 1 µF to 10 µF) be placed from the +VOUT to the -VOUT pins. 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. 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 specifi cations. 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. See the Model Selection table above for the correct rating.

The connection is shown in the diagram at left. The required resistor value is calculated by the formulas: Where R TRIM = The value of the external trim resistor V TRIM = The amount of voltage adjustment required The value of R1, R2, R3 and VREF are given in the table below.

The units do not require external components to operate as specifi ed. 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 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 fi ltering capacitor (C 4) is a high frequency, low resistance electrolytic capacitor. Care must be taken in choosing this capacitor not to exceed the capacitive load specifi cation for the unit. Voltage derating of capacitors should be 80% or above. Notes: 1. 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-xxW (or a similar discrete fi lter 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, or with the addition of the MDCFM-xxW. 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-xxW. Contact the factory for more information. Typical Board Layout: With External Filter/Surge Components 5.

Input noise and surge suppression modules are available for a number of MPD DC/DC power supplies. A connection for one of these modules is illustrated in the typical board layout shown at Typical Connection: With External Filter ModuleUnit Vin (VDC) Input Capacitor Vout (VDC) Output Capacitor 24 100 µF 3.3 220 µF 5.0 220 µF 48 100 µF 9.0 100 µF 12 100 µF 15 100 µF 24 47 µF the bottom of this page For pricing or full technical information, please contact the factory. 7. In many applications simply adding input/output capaci- tors will enhance the input surge protection and reduce output ripple suffi ciently. The input capacitor C 1 and output capacitor C 4 shown in the typical connection diagram above (& board layout drawing below) illustrate their connection. Rec- ommended capacitor values are given in the table.

For the heatsink option, add suffi x “H” to the model number (i.e. MB3024S-05ERW-H) Adapter Plate All models of the MB3000x-xxERW series are available mounted on an adapter plate similar to the one pictured at left. The adapter plate makes it easier to mount the unit to a chassis or to a standard DIN rail. Please contact the factory for more information.
