HoW to use tHe Functions
inPut Voltage
Steady state voltage range is 16 to 40 VDC. Transient range
is 40 to 50 V for a maximum of 120 msec. All models include
a soft-start function to prevent large current draw and minimize
overshoot.
emi inPut FilterS
Internal 500 volt capacitors are connected between the case and
input common and between the case and output common.
Use Interpoint’s FMCE-1528 EMI filter to meet the requirements
of MIL-STD-461C CE03 and CS01 and/or MIL-STD-461D, E and
F CE102 and CS101 levels of conducted emissions. When using
an external input filter it is important that the case of the filter
and the case of the converter be connected through as low as
an impedance as possible. Direct connection of the baseplates
to chassis ground is the best connection. If connected by a
single trace, the trace should be as wide as it is long. See Figure
1.
trim
Both single and dual output models include a trim function.
Output voltage can be trimmed from 60% up to 110% of nominal
V out . When trimming up, do not exceed the maximum output
power. When trimming down, do not exceed the maximum
output current. See Figure 2.
On dual models the positive output is regulated and the negative
output is transformer coupled (cross-regulated) to the positive
output. When trimming the duals, both output voltages will be
adjusted equally. See Figure 3.
