When measuring output ripple & noise, it is recommended that external capacitors (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 specifications. 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 External Trim Capacitive Rating Load Efficiency Fuse Slow-Blow (µF Max) (%, Typ) (mA) For the heatsink option, add suffix “H” to the model number (i.e. MI2024S-12ERU-H) For the chassis mount adapter board option, add suffix “A2S” to the model number (i.e. MI2024S-12ERU-A2S) For the DIN rail mount adapter board option, add suffix “A4S” to the model number (i.e. MI2024S-12ERU-A4S) Derating Curve, >5 VOUT If not used, the Trim pin (pin 4) should be left open. 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: A x R2 VREF Trim Up = RTRIM = -R3 Where: A = x R1 R2 - A VTRIM - VREF Trim Down = RTRIM = Where RTRIM = VTRIM = A x R1 VTRIM - VREF -R3 Where: A = x R2 R1 - A VREF The value of the external trim resistor The amount of voltage adjustment required The value of R1, R2, R3 and VREF are given in the table below.

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. Simple Connection The diagram at left illustrates a typical connection of the MI20xxS-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. VOUT C1 (µF) C3 (µF) 3.3/5 VDC 100 470 12/15 VDC 100 220 Typical Connection 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 specified 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 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. 4. Suggested component values are: Component MOV C1 C2 C3 LDM1 CY1, CY2 VIN: 48V VIN: 24V S14K35 S14K60 330µF/50V 330µF/100V 1 µF/50V 1 µF/100V Refer to the values for the “Simple Connection” 4.7 µH 4.7 µH 1 nF/2 kV 1 nF/2 kV 5. In many applications, simply adding input/output capacitors will enhance the input surge protection & and reduce output ripple sufficiently. In this case, capacitors C1 and C3 could be connected as shown above, without the other filter components. Recommended capacitor values are given in the table above. Typical Board Layout: With Filtering Components The diagram at left shows a typical PC board layout for the MI20xxSERU with the input surge and filter components shown above. The minimum distance between the bonding pads for capacitors CY1 and CY2 must be > 2mm, MicroPower Direct • 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: [email protected] Mechanical Dimensions www.micropowerdirect.com Pin Connections Pin 1 2 3 4 5 6 Single Output -VIN +VIN +VOUT Trim -VOUT Remote On/Off Weight: 0.53 Oz (15g) Mechanical Dimensions: With Optional Heatsink For the heatsink option, add suffix “H” to the model number (i.e. MI2024S-12ERU-H) Pin Connections Pin 1 2 3 4 5 6 Single Output -VIN +VIN +VOUT Trim -VOUT Remote On/Off Weight: 0.707 Oz (20g) Notes: • All dimensions are typical in inches (mm) • Tolerance x.xx = ±0.02 (±0.50) MicroPower Direct • 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: [email protected] Mechanical Dimensions: With A2S Adapter Board www.micropowerdirect.com For the A2S adapter board option, add suffix “A2S” to the model number (i.e. MI2024S-12ERU-A2S) Pin Connections Pin Function 1 Control 2 GND 3 +VIN 4 -VOUT 5 Trim 6 +VOUT Weight: 1.237 Oz (35g) Mechanical Dimensions: With A4S Adapter Board For the A4S adapter board option, add suffix “A4S” to the model number (i.e. MI2024S-12ERU-A4S) Pin Connections Pin Function 1 Control 2 GND 3 +VIN 4 -VOUT 5 Trim 6 +VOUT Weight: 1.903 Oz (54g) Notes: • All dimensions are typical in inches (mm) • Wire Range: 24 - 12 AWG • Tolerance x.xx = ±0.02 (±0.50) MicroPower Direct • 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: [email protected] Mechanical Dimensions: With Heatsink & A2S Adapter Board www.micropowerdirect.com For the A2S adapter board option, add suffix “A2S” to the model number (i.e. MI2024S-12ERU-HA2S) Pin Connections Pin 1 2 3 4 5 6 Function Control GND +VIN -VOUT Trim +VOUT Weight: 1.414 Oz (40g) Mechanical Dimensions: With Heatsink & A4S Adapter Board For the A4S adapter board option, add suffix “A4S” to the model number (i.e. MI2024S-12ERU-HA4S) Pin Connections Pin 1 2 3 4 5 6 Function Control GND +VIN -VOUT Trim +VOUT Weight: 2.086 Oz (59g) Notes: MicroPower Direct • All dimensions are typical in inches (mm) • Wire Range: 24 - 12 AWG • Tolerance x.xx = ±0.02 (±0.50) We Power Your Success - For Less! 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: [email protected]
