The specifi ed maximum capacitive load is for each output. 2. Start up time is measured at nominal input and with a constant resistive load. 3. For ± 5 and ±9 V OUT models, the output accuracy is specifi ed as ±5%. 4. Cross regulation is measured with the main output set at 50% load. The second output is varied from 10% to 100% load. 5. When measuring output ripple, it is recommended that an external ceramic capacitor (approx 10 µF) be placed from the +VOUT to the -VOUT pins. 6. Transient recovery is measured to within a 1% error band for a load step change of 25%. 7. Short circuit protection is provided by a “hiccup mode” circuit. 8. The control input (pin 6) is referenced to the -V IN (pin 2) input. If it is grounded, the unit will shut off. 9. Operation at no-load will not damage the unit, but they may not meet all specifi cations. 10. These units should not be operated over +85°C. Exceeding +85°C may damage the unit. 11. 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. The output fi ltering capacitor (C 3) 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. The board layout illustration below shows a connection for dual output units. 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 line to line), external components are needed. This can be done discretely, or with the addition of the MDCFM-xxW. Contact the factory for more information. 4. Recommended values for components are: Component 24 VIN 48 VIN MOV S20K30 S14K60 C1 330 µF/50V 330 µ F/100V C2 1.0 µF/50V 1.0 µ F/100V L1 4.7 µH 4.7 µ H CY1, CY2 1,000 pF/2 kV 1,000 pF/2 kV 5. Input noise and surge suppression modules are available for a number of MPD DC/DC power supplies. For pricing or full techni- cal information on these modules please contact the factory. 6. 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 C3 shown in the typical connection diagram above illustrate their connec- tion. Recommended capacitor values are given in the table at right.
