Industrial Power Supply
AC-DC
MPI-925A
250W AC-DC AT Power Supply
*Input Voltage: 90~265VAC
*Input Frequency: 47~63Hz
*Inrush Current: Does not exceed 30A at 115VAC input or
60A AC input, at cold start 25
o
C
*Load Range: When all outputs are at 60% rated load
condition, the +5V output is set between 4.90~5.10V and all
other outputs are within the specified voltage accuracy range
*Ripple And Noise: Peak to peak ripple and noise for each
output is < 1% of each output voltage at rated load
115~230VAC
*Line Regulation: < +/-1% at rated load with +/-10% change
in input voltage
*Load Regulation: The output voltage load regulation is less
than the values on the table when each output loading changes
+/-40% from 60% rated load while all other outputs at 60%
rated load
*Hold Up Time: 14ms typ. from the last AC line charging pulse
to the point when +5V drops down to +4.75V
*Output Power: Total DC continuous power is within 200W at
40
o
C ambient temperature. If the input voltage is < 100VAC,
total DC continuous power should not exceed 180W
*Power Good Signal: Goes high 100~500ms after all DC
output is ready
*Power Failure: Goes low 1ms before any DC output falls
*Efficiency: > 65% at nominal line and rated load
*Altitude: 10,000 feet
*Protection: Built-in crowbar circuit automatically shuts down
outputs to avoid damaging external circuits. Trip point of
O.V.P. circuit is between 5.7~7.0V
*Temperature: 0~+70
o
C (operating); -40~+75

C (storage)
*Humidity: 5~95%; non-condensing at 40
o
C (operating)
*Connectors:
AC Input/Output: Meets IEC 320/CEE 22 standard
Tab Terminals: Female 0.250" x 0.032"
CPU Board: Alex 8500-06 or equivalent device
3.5" Disk Drive: AMP 1-480424-0/171822-4 or equivalent
device
*Dimensions: 14.0 x 15.0 x 8.62 cm with +/-0.8mm and +/-
0.4mm tolerance between mounting holes
*MTBF: 156,598 hrs.
FeaturesFeatures
*Safety: UL 1950 / CSA 22.2 No.234 / VDE EN60950
