Notes for use of AC/DC-type synchronous rectification system Forward Type· No parallel connection is allowed. However, connecting two units using diode OR connection for the purpose of redundant operation is possible.· No series connection is allowed. However, series operation will be available if entry of current into the power supply is prevented by way of inserting diodes in

series-parallel to output terminal of the power supply.· Capacity of external connection is not limited unless otherwise specified in overcurrent protection function (OCP) specifications. Please contact us for details in

<Energy-saving and Space-saving>

New power supply system configuration achieved by chassis mount type productRecent DC/DC converters with large output capacity are more commonly provided as power-module type

units with higher component density, having compactness of brick size, half-brick size, and other smaller

sizes. However, such units are accompanied by a demerit that they require external components such as large

aluminum heatsink, cooling fan, and electrolytic capacitor.

On the other hand, 100W ET Series products do not need an additional heatsink despite their amazing

compactness, due to their high efficiency resulting in small self-loss (5.8W for 5V output product).

Furthermore, no external capacitor is needed due to a built-in output electrolytic capacitor they have.

Considering the above, as a way of configuring multi-output power supply system with large output, ETA

Electric is proposing a new method of mounting the ET Series product to a chassis, which has higher flexibility

over the method of mounting a power module on a printed circuit board for the above reasons.

Conditions: *1 : Inrush current varies depending on input/output conditions, such as output impedance of input power supply, input connection

line, power input circuit impedance. *2 : At rated input/output *3 : Measured by a bayonet probe with 100 [MHz] bandwidth oscilloscope at the end of a pair of 150 [mm] long output wires

terminated with a 100 [μF] electrolytic capacitor and a 0.1 [μF] film capacitor, giving no impact on exogenous noise *4 : Within operating temperature range *5 : For 8 hour period after 1 hour warm-up at rated input/output *6 : When output current changed between 25% and 75% of rated output current rapidly at rated input voltage *7 : The wire between the power supply and load should have an enough margin. Keep the line drop within 0.3 [V]. *8 : Inflowing current (IC) = 10 [mA] (maximum) when RC terminal voltage is applied

◎Caution *In order to protect you from possible electrification, do not attempt to touch any components inside the case while the power

supply product is operated. Since the case will also be heated, please be careful when you handle it *The power supply product should be started up after ensuring that the product has 0 [V] output voltage. It should not be restarted

while some output voltage still remains (only for 1.8, 2.5, 3.3, and 05). *In the event that reverse current may flow from the input of the product to input power supply, a blocking diode should be added to

the input line * The safety standard certification of this product is granted under the condition that DC voltage after rectifying/smoothing AC

(ripple voltage 30 [V] or less) is provided to the input side.

*Output will latch (=output shutdown) above here. For recovery, reducing the load to the rated current or below and reentering input are required.

· The power supply unit should be placed/mounted in the direction shown above.· If the power supply unit is used in the direction other than the above, forced air

cooling should be implemented (to discharge excess heat from inside of the unit).· When multiple power supply units are operated side by side, make sure that the

temperature around each unit is within the specified operating temperature range on the specifications before using the units.
