MPE-825A
280W AC-DC ATX power supply

Datasheet

Specifications
Input Voltage:
90~130VAC or 180~260VAC, auto switchable
Input Frequency:
47~63Hz
Inrush Current:
Not exceed 40A at 115VAC input or 80A at 230VAC input, at cold start 25°C
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:
> 20ms at 115VAC input and rated load measured from the end of the last charging pulse to when the main output drops down to 95% output voltage
Power Good:
Goes high 100~500ms after all DC output are ready
Power Fail:
Goes low 0.5ms before any DC output falls
Power On:
TTL compatible signal (active low) used to switch ON the main output. When power on is disconnected from secondary common, all outputs except +5Vsb are turned off
Efficiency:
> 65% at nominal line and rated load
Altitude:
10,000 feet
Protection
Short Circuit: Hiccup mode function against short circuit or over load conditions auto restarts when fault conditions are removed
Output: 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:
Operating: 0~70°C
Storage: -40~+75°C
Humidity:
Operating: 5~95%; non-condensing at 40°C
Connectors:
AC Input/Output: Meets IEC 320/CEE 22 standard
ATX Connector: Alex 9358-20 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:
119,695 hrs.

Safety Standards
Safety:
UL 1950, CSA 22.2 No.234, VDE EN 60 950
