Aiming to meet customer demand for higher power output and
greater reliability in a compact, lightweight unit designed to handle harsh
environmental conditions, Abbott Technologies
has added a
new 500-watt AC-DC model, the CM500, to its power supply product line.
The Sun Valley, Calif.-based designer and manufacturer of
power conversion products says the CM500 is fully sealed to meet IP65/67
standards, and can handle humidity to 100 percent, making them ideal for
Abbott CM500 high-reliability power supplies can be specified
with single-phase inputs ranging from 95 to 260 VAC at line frequencies from 47
to 880 Hz. All input sections include built-in power factor correction, meet
MIL-STD-1399 Section 300 requirements for spike voltage testing and provide
line regulation of plus or minus 1 percent.
Output voltage can be specified from 12 to 48 VDC, and
achieve load regulation of plus or minus 1 percent from no load to full load.
Operating temperature range is -40C to 80C base plate with no power derating,
while ripple and noise are less than 2 percent peak-to-peak over a 20MHz
bandwidth. Efficiency is better than 85 percent, Abbot Technologies says.
Other CM500 features include short circuit protection with
current limiting, in-rush current limiting, remote error sensing, and built-in
test. Electromagnetic compatibility meets the CE101 and CE102 requirements of
MIL-STD-461D. All versions meet MIL-S-901 shock specifications and MIL-STD-167
vibration specs. Nominal size is 3.5 x 6.6 x 1.25 inches and weight is less
than 5 pounds.
