Input-Output Characteristic
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 Vi pin and one Vo 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 combina-
tion with the DC/DC power module to demon-
strate that the output meets the requirement 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.
Case Grounding
For proper operation of the module, the case or
baseplate of the The AV60A dual output series
module does not require a connection to a
chassis ground. If the series is not in a metallic
enclosure in a system, it may be advisable to
directly ground the case to reduce electric field
emissions. Leaving the case floating can help
to reduce magnetic field radiation from common
mode noise currents. If the case has to be
grounded for safety or other reasons, an induc-
tor can be connected to chassis at DC and AC
line frequencies, but be left floating at switching
frequencies. Under the condition, the safety require-
ments are met and the emissions are minimized.
Output Characteristics
Minimum Load Requirement
In order to maintain proper operation and spec-
ifications, there is a 1.5A minimum load require-
ment on +Vo1(3.3V output) for AV60A-048L-
033D025(N), and 0.5A minimum load require-
ment on +Vo1(5V output) for AV60A-048L-
050D033(N). Contact the factory for details.
Output Over-V
Output Over-Voltage Protection
oltage Protection
The over-voltage protection has a separate
feedback loop which activates when the output
voltage is between 120% and 150% of the
nominal output voltage. When an over-voltage
condition occurs, a “ turn off “ signal was sent
to the input of the module which will shut down
the output. The module will restart after power
on again.
Output T
Output Trimming
rimming
Users can increase or decrease the output volt-
age by adding an external resistor between the
TRIM pin and either the Vo (+ ) or Vo ( - ) pins.
The trim resistor should be positioned close to
the module. If the trim feature is not used,
leave the TRIM pin open.
Trimming up by more than 10% of the nominal
output may damage the converter. Trimming
down more than 10% can cause the converter
to regulate improperly. Trim down and trim up
circuits and equations are shown in following
Figures.
Note that at elevated output voltages the
maximum power rating of the module
remains the same, and the output current
capability will decrease correspondingly.
