1000 Watt Enclosed AC-DC Switchers for Extreme Environments
• Power Factor Correction
• Fully compliant with MIL-STD 461D, CE101, CE102
• Meets MIL-S-901 (High Impact shock)
• Meets MIL-STD-810F
• FCC 20780 class A EMI compliance
• Fully sealed to meet IP65
(Optional waterproof connectors available to meet IP67, consult factory)
95-260 VAC 47-880 Hz single phase. Power factor
corrected. Meets MIL-STD-1399, Section 300,
type I requirements (spike voltage test).
EFFICIENCY:
80% typical.
LINE REGULATION:
±1% of nominal over the full range of line
input voltage.
LOAD REGULATION:
±1% for change from no load to full load.
RIPPLE AND NOISE:
Peak-to-peak combined ripple and noise
does not exceed 2% of nominal output
measured with a 20 MHz bandwidth.
Storage, transportation and handling: – 50° to +85°C.
Ambient temperature: -40°C to +80°C baseplate with no
power derating.
ISOLATION:
Input to Output 1500 VRMS
Input to Case 1500 VRMS
Output to Case 500 VDC
SHORT CIRCUIT PROTECTION:
Each unit is completely protected against a
short circuit of any duration. The constant
current circuit is nominally set at 120% of full
load to reduce voltage. The output voltage
automatically restores to normal when the short
is removed.
INPUT PROTECTION:
Internal fuse. In-rush current limiting.
REMOTE ERROR SENSING:
Standard.
MTBF 40,000 hours calculated per MIL-HDBK-217F in
naval sheltered environment.
ELECTROMAGNETIC COMPATIBILITY:
Meets the following MIL-STD-461D requirements:
CE101, CE102.
WEIGHT:
10 to 12 lbs typical.
ENVIRONMENTAL CONDITIONS:
Shock test: Unit meets MIL-S-901 requirements (light
weight).
Vibration test: Unit meets MIL-STD-167,
type I requirements.
Humidity: Power supply operates without any evidence of
degraded performance in non-condensing relative humidity
up to 95%. (Salt-spray option available for condensing
environments).
