Features
*Input Voltage: 90~135VAC (input 115VAC), 180~260VAC
(input 230VAC)
*Input Frequency: 47~63Hz
*Input Current: 7A for 115VAC at without AC outlet; 3.5A for
230VAC
*Inrush Current: 70A max. at cold start
*Switching Frequency: 30KHz typical
*Hold Up Time: 16ms min.
*Brown Out Voltage: 95VAC max. at 60Hz
*Output Power: 250W at 45oC
*Power Up Time: < 20ms for +5V output voltage
*Power Good Signal: The power good signal will not be higher
than 100~500ms after the +5V output stabilizes at its
operating value when the unit is turned on
*Power Failure: The TTL compatible signal will go down at
least 1ms before +5V below 4.75V
*PS ON Signal: TTL compatible signal (active low)
*Efficiency: 75% min. at full load (AC input 230V)
*Altitude: 10,000 feet

Over Voltage: +3.3V from 3.8~4.3V, +5V from 5.7~7V, +12V
from 13.4~15.6V
Over Load: Total output from 130% min. to 150% max.
Short Circuit: Latch off
*Thermal System: Forced air ventilation by DC ball bearing
cooling fan; fan status monitoring is optional
*wTewmwp.DeraatatuShreeeCt4oUe.fcfoicmient: +0.05% per oC
*Temperature: 0~+50oC (operating); -10~+70oC (storage)
*Humidity: 20~90% RH (operating); 10~98% RH (storage)
*Dimensions: 15.0 x 14.0 x 8.6 cm
