Efficiency :
At 20%, 50% & 100% of rated load provide conversion efficiency of 80% min.
Over voltage protection :
+5V: 7V Max.
+3.3V: 4.3V Max.
+12V: 15V Max.
-12V: -15V Max.
+5Vsb: 7V Max.

Temperature range :
Operating : 10 ℃ ~ 50 ℃
Non-operating : -20 ℃ ~ 70 ℃

Humidity :
Operation : 20% ~ 90% RH (Non-Condensing)
Non-Operating : 5% ~ 95% RH (Non-Condensing)

Dimension (mm):
140 * 150 * 97
152 * 165 * 98 (For 750W EPA)

AC Input
Input Voltage : 90Vac ~ 264Vac
Input Frequency : 47 Hz to 63 Hz

Remote ON/OFF
The power supply DC outputs shall be enabled with an active-low, TTL compatible signal ("PS-ON")
When PS -ON is pulled to TTL low, the DC output are enabled.
When PS -ON is pulled to TTL high or open circuited, the main DC outputs are disabled.
