Notes

1. FMCE-0328 can provide up to 84 watts throughput current at 28 volts in and will bring the converter into

compliance with MIL-STD-461C CE03 and CS01 and/or MIL-STD-461D, E and F CE102 and CS101 levels of

conducted emissions.

2. The case ground connection should be as low an impedance as possible to minimize EMI. Direct contact of

baseplate to chassis ground provides the lowest impedance.

3. Case ground for single and dual models is pins 6, 7, and 8. For triple models it is pins 6 and 7.

notes

If calculated result is a negative value, the desired output voltage

is outside the allowed trim range.

When trimming up, do not exceed the maximum output power.

When trimming down, do not exceed the maximum output current.
