Within 0.4% for full input change 24 Vdc to
30 Vdc with load constant.
|
Load Regulation:
|
Within 1.0% for load change of 50% to full load
with line constant.
|
Wave Form:
|
Sinusoidal with a 4% maximum harmonic distortion
into a resistive load.
|
Frequency Stability:
|
±1% drift with time (within the first 8 hours
after 30 seconds warm-up).
|
Frequency Accuracy:
|
±0.5% is initial setting tolerance.
|
Load Power Factor:
|
Full rated output VA from unity to 0.7 power
factor lagging or leading.
|
Isolation Voltage:
|
750 Vdc, input to output; 200 Vdc, input to
case; 200 Vdc, output to case.
|
Insulation Resistance:
|
50 Mohms between input and output, input and
case, output and case, when measured at 50 Vdc.
|
Polarity:
|
Inputs and outputs are isolated, either positive
or negative side may be grounded.
|
Temperature Range:
|
Operating: -55°C to +100°C maximum, at center
of the baseplate. Storage: -55°C to +125°C, ambient.
|
Temperature Coefficient:
|
0.02% / °C from -20°C to +71°C baseplate
temperature, 0.06% / °C over entire range, voltage change.
|
Input Transient Protection:
|
Unit will withstand 80 Vdc for 0.1 second, in
accordance with MIL-STD-704A.
|
Short Circuit Protection:
|
Completely protected against a short circuit
of any duration. Unit must be recycled to restore output to normal
when overload is removed.
|
EMI:
|
Units were designed and built to minimize EMI/EMC
emissions, and comply with the requirements of MIL-STD-461A by
virtue of their topology, construction and enclosure.
|
Reliability:
|
MTBF is calculated per MIL-HDBK-217D at 50°C
baseplate temperature with maximum operating input voltage and
maximum rated output power. The MTBF at ground benign environment
is 340,600 hours and 31,300 hours for air inhabited transport environments.
|
Environment:
|
Encapsulated and hermetically sealed to meet
the environmental requirements of MIL-STD-810C and MIL-E-5400P.
|
Connectors:
|
Standard unit is provided with an input solder
4 pin header. (See option -A for other connectors.)

Options
|
A Option:
|
Special Connectors. A military-type
hermetically sealed connector is provided in place of our standard
input header. To order, replace the "D" in the model
number with "A".
|
B Option:
|
Alternate Head Location. The standard multiple
pin header is relocated to the bottom (baseplate) surface. To order
replace the "D" in the model number with "B".
|
E Option:
|
Severe Shock, Acceleration and Vibration. Enables
all units to withstand 60 g's shock, 50 g's acceleration and 30g's
vibration. To order, add "E" after "D" in the
model number.
|
H Option:
|
Wide Input Voltage. Recenters the input voltage
to provide alternate inputs from 18 Vdc to 32 Vdc. To order, add "H" after "D" in
the model number and specify input voltage range in parentheses
after the entire model number.
|
R Option:
|
Remote Output Adjustment. An adjustment potentiometer
can be remotely located to adjust the output voltage. To order,
add "R" after the "D" in the model number.
