|
Efficiency:
|
25-60%.
|
Line Regulation:
|
Single output within 0.1%, dual output within 0.2%
or 10 mV (whichever is greater) for change from low line to high
line with load constant.
|
Load Regulation:
|
Single output within 0.1%, dual output within 0.2%
or 20 mV (whichever is greater) for change from no load to full
load with line constant.
|
Auxiliary Output Tracking:
|
WW Models. The negative output will track the positive
output within 1% or 100 mV (whichever is greater) for all rated
conditions.
|
Pard (Noise and Ripple):
|
0.02% or 5 mV rms (whichever is greater), 25 mV
P-P at 25 MHz bandwidth.
|
Isolation Voltage:
|
750 Vdc, input to output; 750 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 of output may be grounded.
|
Temperature Range:
|
Operating: -55°C to +100°C maximum, at center of
the baseplate. Storage: -65°C to +125°C, ambient.
|
Temperature Coefficient:
|
0.03% / °C maximum.
|
Input Transient Protection:
|
Unit will withstand 180 Vac for 0.1 second, in accordance
with MIL-STD-704A.
|
Load Transient Recovery:
|
Single output: output voltage returns to regulation
limits within 100 microsecond for auxiliary outputs after 50% change
in load current for units supplying 10 A or less and 200 microseconds
for units supplying more than 10 A. Dual output: output voltage
returns to regulation limits within 200 microseconds after 50%
change in load current
|
Turn-on/Turn-off Overshoot:
|
Single output 0.2% or 20 mV (whichever is greater),
dual output 0.2% or 30 mV (whichever is greater) from nominal voltage
set point.
|
Short Circuit Protection:
|
Completely protected against a short circuit of
any duration. Output automatically restores to normal when overload
is removed.
|
Overvoltage Protection:
|
External modules are available for use with all
models and internal OVP circuit is available for selected models.
Please see -1 option.
|
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 for W5D10 at ground benign environment is
214,600 hours.
|
Environment:
|
Encapsulated and hermetically sealed to meet the
environmental requirements of MIL-STD-810C.
|
Connectors:
|
Standard unit is provided with an input solder pin
header and an output "hermetic seal" stud-type connector.

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 with "A".
|
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.
|
L Option:
|
Remote Turn On/Off. Provides isolated terminals
to turn output on/off with TTL logic signal. To order, add "L" after "D" in
the model number.
|
R Option:
|
An adjustment potentiometer can be remotely located
to adjust the output voltage. To order, add "R" after
the "D" in the model number.
|
Y Option:
|
Remote Error Sensing. Regulator monitors the output
voltage directly at the load using extra "sensing" leads
and compensates for a dc voltage drop of up to .3 volts in the
load lead. This option is inluded at no extra charge when Option
A is ordered. To order, add "Y" after "D" in
the model number.
|
-ER Option:
|
Provides increased reliability by using higher levels
of military grade components. To order, add "-ER" after
the model number.
|
-1 Option:
|
Internal Overvoltage Protection. Provides a crowbar
internal OVP. Input must be recycled to restore output. May inccrease
case size. To order, add "-1" to the end of the model
number.
