It is necessary to equip the external input capacitors at the input of the module.
The capacitors should connect as close as possible to the input terminals ensuring module stability.
External C
in
is Ruby-con BXF series, 100µF/250V.
2. If remote sense is not being used, SENSE pins should connect to corresponding polarity Vout pins.
3. Referred to –Vin pin
4. Input Source Impedance: The power module will operate as specifications without external components, assuming that the source voltage has very low
impedance and reasonable input voltage regulation. Highly inductive source impedances can affect the stability of the power module. Since real-world
voltage source has finite impedance, performance can be improved by adding external filter capacitor. Recommended external capacitor is TBD.
5. A. Iron base-plate dimension is 19” x 3.5” x 0.063” (height is EI standard 2U)
B. Heat sink is optional and P/N: 7G-0021A-F, 7G-0022A-F, 7G-0023A-F, 7G-0024A-F. Please refer to heat-sink selection guide.
6. Standard modules meet EMI Class A or Class B with external components. Contact factory for more information.
7. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. Recommended external capacitor is TBD.
8. BASE-PLATE GROUNDING: When four screw bolts to shield plane, the EMI could be reduced.
9. This product is Listed to applicable standards and requirements by UL.
CAUTION:
This power module is not internally fused. An input line fuse must always be used.
*Due
to advances in technology, specifications subject to change without notice.

OUTPUT VOLTAGE ADJUSTMENT
Output voltage is adjustable for 10% trim up or -20% trim down of nominal output voltage by connecting an external resistor between
the Trim pin and either the +Sense or –Sense pins.
With an external resistor between the Trim and –Sense pin, the output voltage set point decreases.
With an external resistor between the Trim and +Sense pin, the output voltage set point increases.
Maximum output deviation is +10% inclusive of remote sense.
The external Trim resistor needs to be at least 1/8 of rated power.
