2.1 CNT

/g122/g3The products provide a control function allowing the user to turn the output on and off using an external circuit. /g122/g3When CNT disconnects or connects with +Vin or is in the midair, output is on. When CNT connects with –Vin directly, output is off. /g122/g3For 48Vin products, applying a voltage greater than 18V to the CNT pin will enable the output, while applying a voltage less than 4.5V will disable it. For 24Vin products, applying a voltage greater than 24V (it is unlimited when the CNT connects with +Vin directly.) will enable the output, while applying a voltage less than 4.5V will disable it. Grounding of CNT is –Vin. /g122/g3 /g122/g3During operation, the working current of CNT is related to its input voltage.

There is a 1-2V hysteresis between the under-voltage shutdown point and restart up point. /g122/g3When the input power is up than 150%~159% rated input voltage, the input over-voltage protection active, output is cut off. There is a 1-3V hysteresis between the over-voltage shutdown point and restart up point.

2.3 Output over-current protection

/g122/g3AEW series DC/DC converters feature Over-current Protection (OCP) circuits. When output current exceeds 110% to 150% of rated current, such as during a short circuit condition, the output will shutdow n immediately, and can tolerate short circuit conditions indefinitely. /g122/g3When the overcurrent condition is removed, the converter will automatically restart.

2.4 Output over-voltage shutdown (OVP)

/g122/g3The AEW series provides over-voltage prot ection on the output, which will shut the output off if the voltage exce eds 116 to 150% of the nominal output voltage, and the output is shutdown./g3 /g122/g3It must power the module on again to recover the output./g3 /g122/g3If the module is trimmed up to the voltage, which exceeds the 110% rated output voltage, the output over-voltage protection will be probably triggered off./g3 /g122/g3For dual output products: Through testing the over-voltage condition between +Vo and –V, the over-voltage protection active (operating at 116% 150% rated output voltage). /g122/g3For triple output products: Through testing the over-voltage condition between +Vo and COM, the over-voltage protection active. When V o1 exceeds 116%~150% rated output voltage, the over-voltage protection active. After the protection, please turn off the power supply, and restart after 2-3 seconds, the output will be normal.

2.5 Trim function

/g122/g3Output voltage trim range is ±10%. Trimming up by more than 10% of the nominal output may activate the OVP circuit or damage the converter. Trimming down more than 10% can cause improper regulation. /g122/g3The output voltage of the AEW series can be trimmed using the trim pin provided. Applying a voltage to the trim pin through a voltage divider or resistance from the output will cause the output to increase or decrease by up to 10%. /g122/g3When trimming a dual output converter, both outputs trim simultaneously. /g122/g3Trim down and trim up circuits and the corresponding configuration are shown in the following figures.

3.1 Input fuse

The AEW power module has no internal fuse. An external fuse must always be employed! To meet international safety requirements, a 250 Volt rated fuse should be used. If one of the input lines is connected to chassis ground, then the fuse must be placed in the other input line. Standard safety agency regulations requi re input fusing. Recommended fuse ratings for the AEH Series are shown in the following table:/g3 Input voltage Dual out put Triple output Rated 24V input 5A 5A Rated 48Vinput 2.5A 2.5A

3.2 Input filtering

/g122/g3Input filters are included in the converters to help achieve standard system emissions certifications. Some users however , may find that additional input filtering is necessary. The AEW series has an internal switching frequency of 280 kHz so a high frequency capacitor mounted close to the input terminals produces the best results. To reduce reflected noise, a capacitor can be added across the input as shown in following figure, forming a π filter. For conditions where EMI is a concern, a different input filter can be used. Following figure shows an input filter designed to reduce EMI effects. /g122/g3Recommended L & C:

3.3 Output filtering

/g122/g3To reduce output ripple current, the out put capacitor Co should be added on the output. Co=220uF/25V electrolytic capacitor C3=1000uF/16V electrolytic capacitor C2=C4=C6=0.47uF/50V , C5=C7=220uF/35V Dual output: Triple output

High-speed analog or digital loads with dynamic power demands can cause noise to cross the power inductor back onto the input lines. Noise can be reduced by decoupling the load. In most cases, connecting a 10 µF tantalum capacitor in parallel with a 0.1 µF ceramic capacitor across the load will decouple it. The capacitors should be connected as close to the load as possible. 5. Power dissipation /g122/g3Parallel Power Distribution Following figure shows a typical parallel power distribution design. Such designs, sometimes called daisy chai ns, can be used for very low output currents, but are not normally recommended. The voltage across loads far from the source can vary greatly depending on the IR drops along the leads and changes in the loads closer to the source. Dynamic load conditions increase the potential problems. /g122/g3Radial Power Distribution Radial power distribution is the preferred method of providing power to the load. Figure 19 shows how individual lo ads are connected directly to the power source. This arrangement requires additional power leads, but it avoids the voltage variation problems associated with the parallel power distribution technique.

Dynamic and high current lo ads are connected using a radial design, while static and low current loads can be connected in parallel. This combined approach minimizes the drawbacks of a parallel design when a purely radial design is not feasible. /g122/g3Redundant Operation A common requirement in high reliability systems is to provide redundant power supplies. The easiest way to do this is to place two converters in parallel, providing fault tolerance but not load sharing. Oring diodes should be used to ensure that failure of one converter would not cause failure of the second. Figure 21 shows such an arrangement. Upon application of power, one of the converters will provide a slightly higher output voltage and will support the full load demand. The second converter will see a zero load condition and will idle. If the first converter should fail, the second converter will support the full load. When designing redundant converter circuits, Shottky diodes should be used to minimize the forward voltage drop. The voltage drop across the Shottky diodes must also be considered when determining load voltage requirements. \\

Input Reverse V oltage Protection Under installation and cabling conditions wh ere reverse polarity across the input may occur, reverse polarity protection is recommended. Protection can easily be provided as shown in following. In both cases the diode used is rated for 2A/100V. Placing the diode across the inputs rather than in-line with the input offers an advantage in that the diode only conducts in a reverse polarity condition, which increases circuit efficiency and thermal performance. 7. Series operating When converters are connected in series to increase the output voltage, diodes should be added as shown in following figure. Choose low forward voltage drop diodes, such as shottky diodes. The reverse voltage of the diode should be greater than the output voltage, and the diode’ s turn-on current should be greater than the series load current. The maximum operating output current of the series connection should not be greater than the maximum output current of any single converter.

Installation /g122/g3Installation method AEW series converters can be mounted in any orientation, but care should be taken to allow for free airflow. Common placement techniques put heat sources such as power components at the end of the airflow path or provide separate airflow paths. This arrangement keeps other system equi pment cooler and increases component life spans. /g122/g3Derating Curves /g19 /g21/g19 /g23/g19 /g25/g19 /g27/g19 /g20/g19/g19 /g16 /g23 /g19 /g16 /g21 /g19/g19 /g21 /g19/g23 /g19/g25 /g19/g27 /g19 /g20 /g19 /g19 /g36/g80/g69/g76/g72/g81/g87/g3/g55/g72/g80/g83/g72/g85/g68/g68/g87/g88/g85/g72 /g47/g82/g68/g71/g3/g11/g8/g12 /g13007/g2027/g20 /g13007/g2027/g21 series 1: natural convection series 2: maximum case temperature /g28/g19 /g3 Series 1 Series 2
