Safety Consideration
For safety-agency approval of the system in
which the power module is used, the power
module must be installed in compliance with the
spacing and separation requirements of the
end-use safety agency standard, i.e., UL1950,
CSA C22.2 No. 950-95, and EN60950. The
input-to-output 1500VDC isolation is an opera-
tional insulation. The DC/DC power module
should be installed in end-use equipment, in
compliance with the requirements of the ulti-
mate application, and is intended to be supplied
by an isolated secondary circuit. When the sup-
ply to the DC/DC power module meets all the
requirements for SELV(<60Vdc), the output is
considered to remain within SELV limits (level
3). If connected to a 60Vdc power system, dou-
ble or reinforced insulation must be provided in
the power supply that isolates the input from
any hazardous voltages, including the ac
mains. One Vinput pin and one Voutput pin are
to be grounded or both the input and output
pins are to be kept floating. Single fault testing
in the power supply must be performed in com-
bination with the DC/DC power module to
demonstrate that the output meets the require-
ment for SELV. The input pins of the module are
not operator accessible.
Note: Do not ground either of the input pins of
the module, without grounding one of the output
pins. This may allow a non-SELV voltage to
appear between the output pin and ground.
Minimum Load Requirements
There no minimum load required for the AEE
low power high efficiency series.

Output T
Users can increase or decrease the output volt-
age set point of a module by connecting an
external resistor between the TRIM pin. The
trim resistor should be positioned close to the
module. If not using the trim feature, leave
the TRIM pin open.
Trimming up by more than 10% of the nominal
output may damage the converter or trig the
OVP protection. Trimming down more than
10% can cause the converter to regulate
improperly. Trim down and trim up circuits and
the corresponding configuration are shown in
Figure 9 to Figure 10.
Note that at elevated output voltages the
maximum power rating of the module
remains the same, and the output current
capability will decrease correspondingly.
