The specified maximum capacitive load is for each output. 2. Cross regulation is measured with the main output set at 50% load. The second output is varied from 10% to 100% load. 3. When measuring output ripple & noise, it is recommended that external ceramic capacitors (10 µF & 1 µF) be connected in parallel from the +VOUT to the -VOUT pins for single output units and from each output to common for dual output models. 4. Transient recovery is measured to within a 1% error band for a load step change of 25%. 5. The voltage at the Remote On/Off pin (Pin 6) is referenced to the -VIN input (Pin 1). If the on/ off pin is left open, the unit operates. If it is grounded, the unit will shut off. 6. Operation at no-load will not damage these units. However, they may not meet all specifications. The recommended minimum load is given in the model selection table above. 7. 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.

All units will meet class A with the addition of the capacitors shown in the “Simple Connection” diagram. To meet the requirements of Class B, refer to the “Typical Connection” circuit. Contact the factory for more information. 2. To meet the requirements of EN 61000-4-4 (±2 kV), external components are needed, as shown in the “Typical Connection” diagram. Contact the factory for more information. 3. To meet the requirements of EN 61000-4-5 (±2 kV ), external components are needed, as shown in the “Typical Connection” diagram. Contact the factory for more information. Level Class A Class A ±4 kV Contact 10V/m ±2 kV ±2 kV 3 Vrms 0% - 70% Simple Connection The diagram at left illustrates a typical connection of the MI10xxS-xxERU series. Capacitors C1 and C2 are filtering components. They are required to meet the EN 55022 requirements for Class A. The recommended component values are given in the table below. VIN C1 (µF) C3 (µF) 24 VDC 100 10 48 VDC 10 - 47 10 Typical Connection The diagram above illustrates a typical dual output connection of the MI10xxD-xxERU series for an application that requires compliance to input surge and EMC standards EN 55022 and EN 61000 (as specified above). Some notes on these components are: 1. 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. 2. The output filtering capacitors (C3 & C4) 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. 3. Suggested component values are: Component MOV C1 C2 C3 C4 LDM1 CY1, CY2 VIN: 24V S14K35 330µF/50V 1 µF/50V 10 µF 10 µF 4.7 µH 1 nF/2 kV VIN: 48V S14K60 330µF/100V 1 µF/100V 10 µF 10 µF 4.7 µH 1 nF/2 kV 4. In many applications, simply adding input/output capacitors will enhance the input surge protection & and reduce output ripple sufficiently. In this case, capacitors C1, C3 and C4 could be connected as shown above, without the other filter components. Recommended capacitor values are given in the table at left. 5. It is recommended that an external fuse be used. The recommended fuse is shown in the model chart on page 2.
