When measuring output ripple & noise, it is recommended that external capaci- tors (10 µF & 1 µF) be connected in parallel 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. The voltage at the Remote On/Off pin (Pin 6) is referenced to the -VIN input (Pin 2). If the on/off pin is left open, the unit operates. If it is grounded, the unit will shut off. 4. Operation at no-load will not damage these units. However, they may not meet all specifi cations. The recommended minimum load is given in the model selection table above. 5. 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. Derating Curve, >5 VOUT For the heatsink option, add suffi x “H” to the model number (i.e. MI2024S-12ERU-H) For the chassis mount adapter board option, add suffi x “A2S” to the model number (i.e. MI2024S-12ERU-A2S) For the DIN rail mount adapter board option, add suffi x “A4S” to the model number (i.e. MI2024S-12ERU-A4S) External Trim Parameter Output Voltage (VDC) 3.3 5.0 12 15 R1 (k/H9024) 4.841 15.000 10.000 15.000 R2 (k/H9024) 2.870 15.000 2.609 3.000 R3 (k/H9024) 12.400 15.000 15.000 20.000 VREF (V) 1.24 2.50 2.50 2.50 External Trim Notes: An external resistor can be used to adjust the converter output up/down by about 10%. 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. If not used, the Trim pin (pin 4) should be left open. Trim Up = R TRIM = A x R2 -R3 Where: A = VREF x R1 R2 - A VTRIM - VREF Trim Down = R TRIM = A x R1 -R3 Where: A = VTRIM - VREF x R2 R1 - A VREF

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. Typical Connection Typical Board Layout: With Filtering Components Simple Connection The diagram at left illustrates a typical connection of the MI20xxS-xxERU series. Capacitors C 1 and C2 are fi ltering components. They are required to meet the EN 55022 requirements for Class A. The recommended component values are given in the table below. VOUT C1 (µF) C 3 (µF) 3.3/5 VDC 100 470 12/15 VDC 100 220 The diagram above illustrates a typical connection of the MI20xxSERU series. for an application that requires compliance to with input surge and EMC standards EN 55022 and EN 61000 (as specifi ed above). 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. 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. Voltage derating of capacitors should be 80% or above. 4. Suggested component values are: Component VIN: 24V V IN: 48V MOV S14K35 S14K60 C1 330µF/50V 330µF/100V C2 1 µF/50V 1 µF/100V C3 Refer to the values for the “Simple Connection” LDM1 4.7 µH 4.7 µH CY1, CY2 1 nF/2 kV 1 nF/2 kV 5. In many applications, simply adding input/output capacitors will en- hance the input surge protection & and reduce output ripple suf- fi ciently. In this case, capacitors C 1 and C3 could be connected as shown above, without the other fi lter components. Recommended capacitor values are given in the table above. The diagram at left shows a typical PC board layout for the MI20xxSERU with the input surge and fi lter components shown above. The minimum distance between the bonding pads for capacitors C Y1 and C Y2 must be > 2mm,
