Input Voltage:
18V to 32V DC.
Input Power Characteristics:
MIL-STD-704E, Transients as per Fig.9,
including voltage spikes specified in
MIL-E-6051.
DEF STAN 61-5 Part 6 (A1, A2, B1, B2).
MIL-STD-1275A, excluding the single fault
condition.
Isolation:
Input to Output >10M
@ 500VDC.
Input to Chassis >10M
@ 500VDC.
Outputs to Chassis >10M
@ 500VDC.
Efficiency:
Not less than 70% at full load, nominal input
voltage and at 25C baseplate temperature.
Output Voltages:
See Output Rating Table for details.
Other V/A combinations are available.
Contact sales team for further information.
Load, Line & Temperature Regulation (CEB):
Prime Output
±2% of output voltage.
Auxiliary Outputs
±7% of output voltage.
Noise and Ripple (PARD):
Measured over bandwidth DC-20MHz
Prime Output
±2% of output voltage.
Auxiliary Outputs
±2% of output voltage.
Total Effect Band (TEB):
Total combination of CEB + PARD + drift
and warm-up.
Prime Output
±5% of output voltage.
Auxiliary Outputs
±10% of output voltage.
Cross Regulation:
Prime Output
±2% of output voltage.
Auxiliary Output
±7% of output voltage.
Dynamic Load Regulation:
Maximum transient over or undershoot of 5%
of nominal output voltage for a 50% step load
change in 20
s. Recovery within 1ms.
Dynamic Line Regulation:
Maximum transient over or undershoot of 5%
of nominal output voltage with recovery within
1ms for all line transients and surges defined
in Input Power Characteristics above.
Minimum Load Conditions:
For full specified performance
Prime Output
±10% of maximum current.
Auxiliary Outputs
±20% of maximum current.
Output Protection:
Outputs are protected against indefinite
overload and short circuit. Power limiting
circuitry operates at 110-130% of full rated
power. Output voltages recover automatically
following removal of overload.
Remote Sense:
Fitted as standard on +5V single output
converter only. This feature can however be
incorporated on other models in this range if
required. Please contact our sales office for
further information.
Output Overvoltage Protection:
All outputs are protected by means of zener
diode clamps. These limit the output voltage
to 120%, typically, of the nominal value.
Soft Start:
Under all conditions the converters start up in
an orderly fashion. Rise time of supplies is less
than 10ms.
Synchronisation:
These modules can be synchronised to an
external source or to other modules in the
Powermite range.
(Synchronisation frequency = 400kHz
± 5%).
Undervoltage Lockout:
To protect internal circuits against low input
voltages, the converters will not operate below
an input of 13V dc.
Remote Shutdown:
Connecting the shutdown terminal to a voltage
of (
±0.4V) with respect to the prime output
return terminal, will cause the unit to
shutdown. Leaving the terminal open circuit
or connecting it to a logic high signal (3V to
5.5V) will allow the unit to operate.
Hold Up:
Pins are provided for the connection of an
external hold-up capacitor.
(Not available as standard in case size 2A).
EMI:
The units are designed to meet the following
requirements of MIL-STD-461C, Part 2,
category A1b:-
CE01
CS01
RE02
Operating Temperature:
Full specified performance with the baseplate
temperature maintained within the range
-55C to +100C.
Storage Temperature:
-55C to +125C.
Cooling:
Conduction cooling via baseplate.
Humidity:
MIL-STD-810C, Method 507.3, 95% at 25C.
BS3G100, Part 2, Section 3, Sub-Section 3.2,
Para.6.2.
For further information a detailed specification is available upon request. Please contact our sales office.

Construction:
Fully enclosed construction utilising
Aluminium Alloy LM25M to BSI 490.
Paint finish Matt Black to DTD 5555A.
Mounting surface Alochromate finish.
Weight and dimensions:
The maximum weight is 575 grams.
Refer to outline drawing for unit dimensions
and fixing positions.
Vibration:
MIL-STD-810E, Method 514.4 category 5.
BS3G100, Part 2, Section 3, Sub-Section 3.1,
tests 4.3, 4.4.2 and 4.4.4.
Acceleration:
MIL-STD-810E, Method 513.4 Procedure 11.
BS3G100, Part 2, Section3, Sub-Section 3.6.
Shock:
MIL-STD-810E, Method 516.4 Procedure V.
DEF-STAN-07-55 Part 2, Section 1.1 Test A2
(100g, 6ms, 3 shocks per axis).
Salt Mist:
BS3G100, Part 2, Section 3, Sub-Section3.8.
Explosion Proofness:
BS3G100, Part 2, Section 3, Sub-Section 3.5.
Nuclear Hardening:
The circuitry of all Powermite converters is
designed to limit the effects of nuclear
radiation.
Maintainability:
Units are constructed in a non-hermetically
sealed two part housing. Internal circuitry is
protected by means of conformal coating.
All Powermite modules are repairable.
MTBF:
The MTBF for any unit in the Powermite
range, calculated in accordance with
MIL-HDBK-217, can be provided upon
request.
HI-REL versions with active components
screened to JANTX, MIL-STD-883 or similar
are available.
Shelf Life:
The shelf life of the units is ten years, they may
be left in deep store, without the need for
intermittent powering-up or any form of
servicing for the period of the shelf life.
Burn In:
All units are subjected to an environmental
stress screening programme. For standard
versions this consists of a 48 hour bake at
85C baseplate temperature. High reliability
versions are subjected to 10 minutes of random
vibration followed by 48 hours of power and
temperature cyclingbetween -55C and +85C,
with full load applied.
