Specifications apply at the backplane, 0-55°C.
+5VSTDBY:Up to 1A may be available if provided by the user through pins
8 and 21 of the diagnostic connector.
Input Voltage: 90VAC Min to 264VAC Max, Single continuous range
Input Frequency: 47Hz Min to 66Hz Max (across full input voltage range)
360Hz to 440Hz: (Not Recommended. Leakage currents
may exceed safety limits, 132VAC Max)
DCV Input: (Not Recommended. Input connector is not certified for
DCV input.)
Inrush Current:
E8401A: Input Voltage 110VAC:25A Typical
Input Voltage 264VAC:55A Typical
E8403A: Input Voltage 110VAC:40A Typical
Input Voltage 264VAC:60A Typical
Note: If inrush current causes mains supply voltage to temporarily drop
below the required minimum voltage (90VAC), the mainframe may not turn
on properly.
Total Input Power may be estimated by the following expression:
1.4 * (Output Power + 70W)
Notes:Total Power Input in Watts or VA, Power Factor Corrected.
Output Power in Watts = Sum of Voltage times Current for the seven
Expression is valid for full output load and 90VAC.
Efficiency increases slightly with higher input voltage.
Efficiency decreases slightly with lower output load.
Power Switch: On/Standby switch on front.
Indicators: ON indicator green when mainframe powered on
Standby indicator amber in Standby and ac power line connected.
May be switched On/Standby remotely via Diagnostic Connector.
